- Definition of chronic pain: Chronic pain is pain that persists or recurs for longer than 3 months, often beyond normal tissue healing time. It is distinguished from acute pain by its duration and the complex interplay of biological, psychological, and social factors that maintain it.
- Biopsychosocial model: This framework recognizes pain as a multidimensional experience influenced by biological processes (tissue damage, inflammation), psychological factors (mood, cognition, coping), and social contexts (culture, support systems, work environment).
- Prevalence and impact: Chronic pain affects approximately 20% of adults globally, making it a leading cause of disability and healthcare utilization. It contributes to reduced quality of life, lost productivity, and increased healthcare costs across health systems.
- Types of chronic pain: Common categories include nociceptive pain (from tissue injury), neuropathic pain (from nerve damage), and nociplastic pain (altered nociception without clear tissue or nerve damage). Many patients experience mixed pain types.
- Central sensitization: A key mechanism in chronic pain where the central nervous system becomes hypersensitive, amplifying pain signals. This can occur even after initial tissue healing, leading to persistent pain perception and widespread sensitivity.
- Pain as a disease: The International Association for the Study of Pain now recognizes chronic pain as a disease entity in its own right, not merely a symptom of other conditions. This shift influences treatment approaches and research funding.
- Risk factors for chronicity: Contributors include genetic predisposition, psychological distress, poor coping strategies, socioeconomic disadvantage, and inadequate acute pain management. Early identification of these factors can guide preventive strategies.
- Stigma and patient experience: Many patients with chronic pain face skepticism from providers and society, leading to underdiagnosis and undertreatment. Understanding the patient perspective is critical for compassionate, effective care.
- Multimodal treatment approach: Combining pharmacologic, physical, psychological, and interventional therapies addresses the multifaceted nature of chronic pain. This approach improves outcomes by targeting different pain mechanisms and reducing reliance on any single modality, particularly opioids.
- Nonpharmacologic interventions: Evidence supports exercise therapy, cognitive behavioral therapy, mindfulness, and acupuncture for chronic pain. These interventions help patients improve function, reduce disability, and develop self management skills without medication related risks.

- Providing psychotherapy or psychological treatment without licensure
- Making independent treatment decisions without physician oversight
Quick Revision
- Chronic pain persists beyond 3 months and is best understood through the biopsychosocial model.
- Types include nociceptive, neuropathic, and nociplastic pain; central sensitization often plays a role.
- Chronic pain is recognized as a disease entity and affects millions globally.
- Pain management coordinators support patient intake, education, and care coordination within defined scope.
