Chest Pain
Chest pain is a common and often alarming symptom characterized by discomfort or pressure felt anywhere in the chest area. It can range from mild aches to severe, crushing sensations and can arise from a wide variety of underlying conditions, some benign and others life-threatening. Due to its potential association with serious cardiac events, chest pain is a frequent reason for emergency medical visits, underscoring its significant clinical importance.
The biological basis of pain, including chest pain, involves complex interactions within the nervous system. Nociceptors, specialized sensory neurons, detect potentially harmful stimuli such as tissue damage, inflammation, or ischemia, and transmit these signals to the brain, where they are interpreted as pain. The perception and experience of pain are highly individualized, influenced by a combination of physiological, psychological, and genetic factors. Genetic variations can affect pain pathways, neurotransmitter systems, and inflammatory responses, contributing to differences in pain sensitivity, chronicity, and response to treatment. For instance, genome-wide association studies (GWAS) have identified numerous genetic loci associated with various pain phenotypes, including acute post-surgical pain[1], chronic widespread pain[2], neuropathic pain[3], and pain severity in conditions like dysmenorrhea[4]. Specific genes or chromosomal regions, such as 1p13.2 near the nerve growth factor locus [4], 5p15.2 [2], and variants in genes like protein-kinase C [5], have been linked to pain experiences. Genetic analysis has also explored pain in specific contexts, such as acute post-radiotherapy pain in breast cancer patients[6], cancer pain[7], and multisite chronic pain[8], highlighting the diverse genetic architecture underlying different pain types.
Clinically, understanding the genetic underpinnings of chest pain can aid in more precise diagnosis, risk stratification, and personalized treatment strategies. While immediate medical evaluation is crucial for acute chest pain, genetic insights may help differentiate between cardiac and non-cardiac causes, predict an individual’s susceptibility to chronic pain conditions, or inform optimal analgesic choices[7]. This personalized approach holds promise for improving patient outcomes and reducing unnecessary diagnostic procedures.
The social importance of chest pain extends beyond individual health. Chronic or recurrent chest pain can significantly impair an individual’s quality of life, leading to disability, psychological distress, and a substantial burden on healthcare systems. Genetic research contributes to a deeper understanding of pain mechanisms, potentially leading to the development of novel therapies and preventative measures. By identifying individuals at higher genetic risk for certain pain conditions, public health initiatives can be tailored to promote early intervention and support, thereby mitigating the broader societal impact of chest pain and related chronic pain syndromes.
Limitations
Section titled “Limitations”Understanding the genetic underpinnings of complex traits like chest pain faces several inherent limitations, stemming from methodological constraints, the diversity of human populations, and the intricate nature of biological systems. These factors necessitate careful interpretation of findings and highlight areas for future research.
Methodological and Statistical Constraints
Section titled “Methodological and Statistical Constraints”Current genome-wide association studies (GWAS) are constrained by the technology used for genotyping. Existing platforms typically capture only about two-thirds of known common genetic variations across the human genome, which may increase the risk of false discoveries by missing true associations or overestimating effects [1]. While some studies involve large cohorts, the “relatively small” sample size for a GWAS can still impact the robustness of findings, emphasizing the critical need for replication with larger and more diverse datasets by independent investigators to confirm novel genetic associations[1].
Furthermore, GWAS primarily identify statistical relationships between genetic markers and a phenotype, rather than directly elucidating the underlying biological mechanisms [1]. For identified candidate genetic loci that lack clear annotation or known function, extensive additional work is required in both animal models and human studies to characterize their biological roles and how they contribute to pain pathways[1]. Methodological practices, such as removing SNPs with low imputation quality or minor allele frequency, and applying stringent significance thresholds, are essential for data quality but may also inadvertently exclude genuine, rarer genetic signals.
Generalizability and Phenotypic Heterogeneity
Section titled “Generalizability and Phenotypic Heterogeneity”The generalizability of genetic findings for pain conditions is significantly impacted by population-specific genetic architectures. Many studies are predominantly conducted in populations of European ancestry, meaning their results may not be directly transferable to other ethnic groups due to notable differences in pain responses, analgesic efficacy, and genetic variations across diverse populations[1]. To mitigate this, some studies specifically remove samples based on ancestry to create a homogeneous dataset for analysis, which, while improving internal validity, inherently restricts the external generalizability of the findings [3].
The definition and measurement of complex phenotypes like chest pain also present challenges. Pain is subjective and can manifest with varying characteristics and etiologies, leading to phenotypic heterogeneity within study cohorts. While efforts are made to adjust for demographic factors such as age, sex, and body mass index (BMI), these variables are often significantly different between case and control groups, necessitating robust statistical adjustments that may not fully capture all confounding effects[3]. Such differences highlight the complex interplay of biological and lifestyle factors that can influence pain perception and complicate the identification of specific genetic associations.
Unexplained Heritability and Mechanistic Gaps
Section titled “Unexplained Heritability and Mechanistic Gaps”Despite advances in identifying genetic variants associated with various pain conditions, a substantial portion of the heritability often remains unexplained by common single nucleotide polymorphisms (SNPs). For instance, SNP-based heritability estimates for conditions like back pain might only account for a fraction of the total genetic influence, suggesting a significant “missing heritability” that could be attributed to rarer variants, structural variations, or complex epistatic interactions not fully captured by current GWAS designs[9]. This gap indicates that the full genetic architecture of chest pain is likely more intricate than current methods can comprehensively resolve.
Furthermore, even when genetic associations are statistically robust, the precise biological mechanisms by which these variants influence pain perception, processing, or susceptibility are often unknown. The complex interplay between genetic predispositions and environmental factors, including lifestyle, comorbidities, and specific exposures, contributes to the overall risk and manifestation of pain conditions. Unraveling these gene-environment interactions and characterizing the downstream molecular and cellular pathways affected by identified genetic variants represents a considerable knowledge gap that requires extensive functional genomic and experimental validation beyond initial association findings.
Variants
Section titled “Variants”Genetic variations play a crucial role in an individual’s predisposition to various health conditions, including those that manifest as chest pain. Chest pain can stem from diverse etiologies, such as cardiovascular disease, musculoskeletal issues, or neuropathic conditions, each influenced by a complex interplay of genetic and environmental factors. Several single nucleotide polymorphisms (SNPs) have been identified that contribute to the genetic architecture underlying pain perception and related traits.
The variant rs4977575 is located in the CDKN2B-AS1gene, also known as ANRIL, a long non-coding RNA (lncRNA). This gene resides within the 9p21 region, a genomic locus extensively associated with an increased risk of coronary artery disease (CAD).CDKN2B-AS1 influences the expression of nearby tumor suppressor genes, CDKN2A and CDKN2B, which are important regulators of cell growth. Alterations in CDKN2B-AS1 activity due to variants like rs4977575 can affect arterial plaque formation, a hallmark of CAD, thereby impacting an individual’s susceptibility to ischemic chest pain. Similarly,rs55730499 is associated with the LPAgene, which encodes apolipoprotein(a), a key component of lipoprotein(a) [Lp(a)]. Elevated Lp(a) levels are a significant and causal risk factor for atherosclerotic cardiovascular disease, which frequently presents with chest pain. Variants inLPAcan influence Lp(a) levels, thus modulating the risk of developing arterial plaques and subsequent angina. Genome-wide association studies (GWAS) consistently identify genetic loci influencing chronic pain and multisite chronic pain, underscoring the broad genetic involvement in pain pathways[8].
Another variant, rs140367095 , is linked to the DSTNP5 - PARD3B locus, with PARD3B (Partitioning-defective 3 homolog B) being a gene essential for establishing cell polarity and maintaining the structural integrity of tissues. PARD3B is involved in critical cellular processes such as cell migration and the formation of cell-cell junctions. Disruptions in these fundamental cellular mechanisms, potentially influenced by variants like rs140367095 , can contribute to inflammation, tissue dysfunction, or altered nerve signaling, which are underlying factors in various pain conditions. While not directly specific to cardiovascular chest pain, the gene’s role in cellular architecture suggests a potential influence on tissue health and repair processes, which can indirectly affect pain perception or susceptibility to conditions causing pain. Research into the genetic architecture of pain, including studies on chronic back pain and acute post-radiotherapy pain, continues to reveal how diverse genetic variations contribute to the individual experience of pain[9]. These studies highlight the complex genetic landscape that shapes an individual’s response to pain, encompassing a wide range of physiological and pathological processes.

Defining Pain Phenotypes and Operational Criteria
Section titled “Defining Pain Phenotypes and Operational Criteria”The identification and study of pain phenotypes rely on precise operational definitions and diagnostic criteria established for research purposes. For instance, “Back pain” (BP) is commonly defined by self-report, where individuals are identified as cases if they report experiencing back pain in response to specific survey questions about pain types within a given timeframe, such as the last month[9]. This approach establishes a clear operational definition for epidemiological and genetic studies. Furthermore, chronic pain conditions are often delineated by duration, with “chronic BP” specifically defined as pain persisting for at least three months[9]. Similar methodologies apply to other pain types, such as “neck or shoulder pain,” which is defined by a positive response to a direct inquiry about its presence[3].
Measurement approaches for pain often involve subjective scales and thresholds to categorize individuals. For example, cases of acute post-radiotherapy pain in breast cancer patients are defined by a pain score of four or greater, while those with scores below four serve as a reference group[6]. This method provides a quantitative criterion for severity gradation, enabling categorical classification within research cohorts. Other pain phenotypes investigated in genetic studies, such as dysmenorrhea pain severity, chronic postoperative pain, diabetic neuropathic pain, and acute post-surgical pain, also necessitate specific measurement and diagnostic criteria for their accurate assessment and inclusion in studies[4].
Classification Systems and Severity Gradations
Section titled “Classification Systems and Severity Gradations”Pain is classified into various systems based on anatomical location, duration, and underlying etiology, reflecting a categorical approach to understanding its diverse manifestations. Examples include classifications by body region, such as back pain[9]and neck or shoulder pain[3], or by specific conditions like dysmenorrhea [4]and diabetic neuropathic pain[3]. These nosological distinctions allow for the focused study of distinct pain experiences. Severity gradations are a critical component of pain classification, often utilizing numerical scales or thresholds.
The distinction between acute and chronic pain represents a fundamental classification system, with chronic conditions typically defined by a sustained duration. For example, back pain is classified as chronic when it persists for at least three months[9]. This temporal criterion helps differentiate transient pain from persistent conditions that may have distinct underlying mechanisms and treatment implications. Such clear, categorical classifications are essential for designing research studies, particularly in large cohorts like the UK Biobank, where consistent phenotyping is crucial for identifying genetic associations[9].
Terminology and Standardized Vocabularies
Section titled “Terminology and Standardized Vocabularies”The nomenclature used in pain research includes a range of key terms that precisely define different pain experiences and conditions. Standardized vocabularies are employed to ensure consistency across studies, encompassing terms like “dysmenorrhea,” “back pain,” “chronic postoperative pain,” “diabetic neuropathic pain,” “acute post-surgical pain,” and “acute post-radiotherapy pain”[4]. These terms facilitate clear communication and comparability of findings within the scientific community.
Research criteria for defining pain often leverage structured questionnaires and self-report mechanisms to collect data consistently. For instance, studies utilizing the UK Biobank define pain phenotypes through participant responses to direct questions, such as “Pain type(s) experienced in last month” or specific inquiries about the presence of pain in particular areas[9]. This reliance on standardized questions and predefined response options forms a critical basis for operationalizing pain definitions, enabling large-scale genetic investigations where uniformity in data collection is paramount[10].
Causes of Chest Pain
Section titled “Causes of Chest Pain”The experience of chest pain, like other forms of pain, arises from a complex interplay of genetic predispositions, environmental exposures, and the presence of various health conditions. Research indicates that the underlying mechanisms involve both inherited sensitivities and external factors that can trigger or exacerbate pain pathways.
Genetic Underpinnings of Pain Sensitivity
Section titled “Genetic Underpinnings of Pain Sensitivity”Genetic factors contribute significantly to an individual’s susceptibility to pain, including conditions that may manifest as chest pain. Studies, including genome-wide association studies (GWAS), have identified numerous inherited variants and polygenic risk scores associated with different chronic pain conditions, suggesting a complex genetic architecture where many genes with small effects collectively influence pain perception[8]. This genetic predisposition can influence the development of chronic pain by altering neural pathways involved in pain processing, inflammation, and tissue repair.
Specific genetic loci have been linked to particular types of pain, highlighting the diverse genetic influences on pain phenotypes. For instance, an association near the nerve growth factor locus on chromosome 1p13.2 has been identified with pain severity in dysmenorrhea[4]. Furthermore, research has revealed sex-specific genetic involvement, such as associations of Chr1p35.1 (ZSCAN20-TLR12P) and Chr8p23.1 (HMGB1P46) with diabetic neuropathic pain[3], and an association of GFRA2 on Chr8p21.3 also with diabetic neuropathic pain[3]. These findings underscore how inherited variants can modulate an individual’s threshold and response to painful stimuli.
Environmental and Lifestyle Contributions
Section titled “Environmental and Lifestyle Contributions”Beyond genetics, environmental factors play a crucial role in the manifestation and severity of pain. These factors encompass a broad range of influences, from lifestyle choices to specific exposures, and contribute to the overall risk for chronic pain[9]. While the precise mechanisms by which many lifestyle or dietary factors directly contribute to chest pain are still being elucidated, general environmental stressors and exposures can trigger or worsen pain experiences.
Specific external events and medical interventions are significant environmental triggers for pain. Examples include acute post-radiotherapy pain experienced by breast cancer patients, where the treatment itself induces pain[6]. Similarly, acute post-surgical pain is a direct consequence of a medical procedure, demonstrating how physical trauma and the body’s response to it are potent environmental contributors to pain[1]. These instances illustrate how direct environmental exposures can initiate or intensify pain signals.
Interplay of Genes, Environment, and Health Conditions
Section titled “Interplay of Genes, Environment, and Health Conditions”The development and persistence of pain often involve complex interactions between an individual’s genetic makeup and their environment. A genetic predisposition can interact with environmental triggers, meaning that individuals with certain inherited variants may exhibit altered pain responses or increased susceptibility when exposed to particular stressors[9]. This gene-environment interaction highlights a nuanced model where neither genes nor environment act in isolation, but rather modulate each other’s effects on pain perception and experience.
Comorbidities and other medical factors are also significant contributors to various pain conditions. For example, pre-existing health issues like diabetes are strongly associated with neuropathic pain[3]. Cancer patients can experience neuropathy or pain following radiotherapy[11]. Additionally, psychological factors such as anxiety have been linked to pain problems, indicating a complex relationship between mental health and physical pain[12]. These contributing factors demonstrate how an individual’s overall health status and medical history profoundly influence their vulnerability to and experience of pain.
Biological Background of Chest Pain
Section titled “Biological Background of Chest Pain”Chest pain, a common and often concerning symptom, arises from complex biological processes involving intricate interactions between molecular pathways, cellular functions, genetic predispositions, and systemic physiological disruptions. Understanding these underlying mechanisms is crucial for comprehending the diverse manifestations and perceptions of pain within the thoracic region. The experience of pain, whether acute or chronic, involves a sophisticated network of sensory neurons, signaling molecules, and central nervous system processing that can be influenced by a myriad of factors.
Neural Transmission and Nociceptive Signaling
Section titled “Neural Transmission and Nociceptive Signaling”The perception of pain, including that experienced as chest pain, fundamentally relies on the intricate network of the nervous system and the process of nociception. This involves specialized sensory neurons that detect noxious stimuli and transmit these signals through molecular and cellular pathways to the brain. Key biomolecules, such as nerve growth factor (NGF), play a crucial role in the development and sensitization of these pain pathways, with genetic associations near the NGF locus observed in pain conditions like dysmenorrhea[4]. Similarly, specific genetic variations, such as those involving GFRA2 on chromosome 8p21.3, have been linked to neuropathic pain, highlighting the role of particular receptors in mediating pain signals[3]. The complexity of pain biology stems from this intricate network of multiple gene polymorphisms and environmental factors, each subtly influencing various mechanisms that contribute to individual variations in pain sensitivity and responses to analgesic treatments[1].
Genetic Architecture and Regulatory Mechanisms of Pain
Section titled “Genetic Architecture and Regulatory Mechanisms of Pain”Individual differences in pain perception, including the threshold and intensity of chest pain, are significantly influenced by genetic mechanisms. Genome-wide association studies (GWAS) have begun to unravel the genetic architecture of various pain conditions, identifying numerous loci associated with traits such as dysmenorrhea, back pain, chronic postoperative pain, acute post-surgical pain, multisite chronic pain, and diabetic neuropathic pain[4]. These studies indicate that gene functions, regulatory elements, and gene expression patterns contribute to the individual variability in pain responses. For instance, pathway analyses in studies of acute post-radiotherapy pain or multisite chronic pain have pointed to the involvement of specific Gene Ontology categories related to biological processes and curated gene sets, suggesting that coordinated gene activity underlies pain phenotypes[6]. The genetic basis of these human variations is essential for elucidating the molecular underpinnings of pain sensitivity and for developing more effective, personalized pain management strategies[1].
Immune, Metabolic, and Systemic Interactions in Pain
Section titled “Immune, Metabolic, and Systemic Interactions in Pain”Beyond direct neural signaling, pain, including chronic or acute chest pain, is profoundly influenced by systemic interactions involving the immune and metabolic systems. There is significant cross-talk between the immune system and the nervous system in the processes of nociception and sensitization that can lead to chronic pain[8]. Neuroinflammation, a cellular function within the nervous system, is specifically implicated in the development of neuropathic pain[8]. Furthermore, metabolic processes and conditions like obesity are often comorbid with chronic pain, with metabolically active adipose tissue shown to affect pain perception and inflammation[8]. These tissue interactions and systemic consequences underscore how broader physiological states, such as chronic inflammation, can modulate pain pathways and contribute to the overall experience of pain throughout the body.
Pathophysiological Processes and Comorbid Conditions
Section titled “Pathophysiological Processes and Comorbid Conditions”Pain, particularly chronic pain, is frequently intertwined with a range of pathophysiological processes and comorbid conditions, influencing its presentation and severity, which can include chest pain. Chronic pain is a common component of many neurological diseases, such as Parkinson’s disease, Multiple Sclerosis, and migraines, indicating shared underlying disease mechanisms[8]. Autoimmune disorders are also known to cause or be associated with chronic pain, highlighting the role of immune dysregulation in pain etiology[8]. Moreover, disruptions in homeostatic processes, such as sleep changes and loss of circadian rhythm, are prevalent in individuals with chronic pain, influencing symptom severity and intensity[8]. The interplay between pain and mental health conditions, such as adolescent anxiety, further illustrates the complex, multi-systemic nature of pain as a trait[12].
Pathways and Mechanisms
Section titled “Pathways and Mechanisms”The perception and experience of chest pain arise from complex, interconnected biological pathways, often influenced by genetic predispositions. Research, primarily through genome-wide association studies (GWAS) and pathway analyses, has begun to unravel the genetic architecture underlying various pain conditions, providing insights into potential molecular mechanisms relevant to pain signaling and regulation[9]. These studies highlight how genetic variations can modulate the sensitivity and processing of nociceptive stimuli, contributing to individual differences in pain perception.
Genetic Modulation of Nociceptive Signaling Pathways
Section titled “Genetic Modulation of Nociceptive Signaling Pathways”Genetic variations play a crucial role in shaping the efficacy of nociceptive signaling pathways, which are fundamental to pain transmission. For instance, associations have been identified near the nerve growth factor (NGF) locus, suggesting that genetic factors influencing NGF production or signaling can impact pain severity[4]. NGF is a key neurotrophin involved in the development and sensitization of nociceptive neurons; thus, altered NGF signaling due to genetic variations could affect receptor activation and subsequent intracellular cascades that lead to pain perception. Similarly, theGFRA2gene, encoding Glial Cell Line-Derived Neurotrophic Factor Family Receptor Alpha 2, has been associated with neuropathic pain, indicating that genetic variations in receptors mediating neurotrophic support can influence pain pathways[3]. These genetic insights underscore how specific receptor-ligand interactions and downstream signaling events are fine-tuned by an individual’s genome, impacting the initiation and propagation of pain signals.
Transcriptional and Post-Translational Regulatory Mechanisms
Section titled “Transcriptional and Post-Translational Regulatory Mechanisms”The precise regulation of gene expression and protein activity is critical for controlling pain responses, and genetic factors contribute significantly to these regulatory mechanisms. Genome-wide studies identify candidate loci associated with various chronic pain conditions, implying that variations in genes involved in transcriptional regulation can alter the expression levels of pain-related proteins[7]. Furthermore, these genetic influences extend to post-translational modifications and allosteric control, where subtle changes in protein structure or function, dictated by genetic polymorphisms, can profoundly impact enzyme activity, receptor sensitivity, or ion channel function. Pathway-based analyses in pain research often highlight biological processes where gene regulation is central, suggesting that genetic variants might dysregulate the synthesis or modification of proteins essential for pain modulation[8]. Such regulatory dysfunctions can shift the balance towards increased pain sensitivity or reduced analgesic responses.
Systems-Level Integration and Network Interactions in Pain
Section titled “Systems-Level Integration and Network Interactions in Pain”Pain perception is an emergent property of complex network interactions, where multiple pathways crosstalk and integrate at various hierarchical levels. Studies on multisite chronic pain reveal shared genetic factors across different musculoskeletal pain conditions, indicating that common underlying genetic architectures contribute to a broader pain susceptibility[8]. This suggests extensive pathway crosstalk, where genetic variants in one pathway can influence the function of others, leading to a systemic impact on pain processing. The integration of genetic findings from large cohorts allows for a systems-level view, identifying how networks of genes and their products interact to produce complex pain phenotypes, rather than focusing on isolated pathways[9]. These network interactions involve hierarchical regulation, where master regulators or key nodes, influenced by genetic variations, can exert widespread effects on pain sensitivity and duration.
Disease-Relevant Pathway Dysregulation and Therapeutic Targets
Section titled “Disease-Relevant Pathway Dysregulation and Therapeutic Targets”Understanding the genetic underpinnings of pain pathways provides crucial insights into disease-relevant mechanisms and potential therapeutic targets. Genetic associations with chronic postoperative pain or acute post-radiotherapy pain identify specific pathways that are dysregulated in these conditions, offering avenues for intervention[6]. For example, compensatory mechanisms might arise in response to genetically predisposed pathway dysregulation, which could be exploited or targeted to alleviate pain. Identifying genes likeGFRA2 or loci near NGF highlights specific molecular components that, when modulated, could offer therapeutic benefits by restoring normal signaling or reducing hypersensitivity [4]. The ongoing elucidation of the genetic architecture of various pain types aims to pinpoint precise molecular targets for developing more effective and personalized pain management strategies.
Genetic Insights into Pain Susceptibility and Prognosis
Section titled “Genetic Insights into Pain Susceptibility and Prognosis”Genetic research into diverse pain conditions, such as dysmenorrhea, back pain, and chronic postoperative pain, provides crucial insights into the susceptibility and long-term trajectory of pain experiences. Studies have identified genetic loci associated with pain severity in conditions like dysmenorrhea, near the nerve growth factor locus, suggesting specific biological pathways influencing pain perception[4]. Similarly, genome-wide association studies (GWAS) on large cohorts have elucidated the genetic architecture of chronic back pain, identifying specific loci that contribute to its development and progression[13]. These findings are vital for predicting individual outcomes, understanding disease progression, and identifying patients at higher risk for developing chronic or severe pain, thereby informing prognostic assessments across various pain manifestations[14].
Applications in Risk Assessment and Treatment Strategies
Section titled “Applications in Risk Assessment and Treatment Strategies”Genetic insights offer significant clinical utility for risk assessment and guiding treatment selection in pain management. By identifying genetic variants linked to acute post-surgical pain or chronic postoperative pain, clinicians can potentially stratify individuals based on their genetic predisposition to pain severity and chronicity[1]. This personalized medicine approach can lead to tailored prevention strategies and more effective analgesic regimens, as demonstrated by research exploring genotypes related to pain and analgesia response in conditions like Irritable Bowel Syndrome[15]. Such genetic information can enhance diagnostic precision, refine risk stratification models for high-risk individuals, and inform monitoring strategies to optimize patient care and improve treatment outcomes for complex pain phenotypes.
Comorbidities and Overlapping Pain Phenotypes
Section titled “Comorbidities and Overlapping Pain Phenotypes”The genetic landscape of pain often reveals associations with other health conditions and contributes to overlapping phenotypes, highlighting the systemic nature of pain. For instance, research has explored the joint genetic investigation of adolescent anxiety and pain problems, indicating shared genetic underpinnings that can influence syndromic presentations[12]. Furthermore, studies on multisite chronic pain and the genetic architecture of back pain have identified common risk factors and related conditions, emphasizing the importance of a holistic view in patient assessment[8]. Understanding these genetic associations can help identify individuals with complex pain presentations, anticipate potential complications, and develop integrated management strategies that address both the pain and its associated comorbidities.
