Patterns of Pain lasting more than 3 months
Chronic pain is defined by its temporal duration (persisting beyond the expected healing time — typically three months) rather than by tissue damage or injury severity. The ICD-11 introduced a new chronic pain classification distinguishing chronic primary pain (where pain itself is the condition — chronic widespread pain, fibromyalgia, complex regional pain syndrome, non-specific low back pain) from chronic secondary pain (where pain persists as a sequela of a primary pathology — osteoarthritis, cancer pain, neuropathic pain from nerve injury). Chronic pain involves neuroplastic changes — central sensitisation — whereby the nervous system becomes amplified in its pain signalling, making pain persist and spread beyond the original injury site. Psychological factors (depression, anxiety, catastrophising, fear-avoidance, low self-efficacy) and social factors (isolation, occupational difficulties, socioeconomic stress) independently amplify and maintain chronic pain, necessitating a biopsychosocial model of assessment and management.

The Evidence

Overall pictureHigh evidence base
Chronic pain is well-studied — and best managed across multiple dimensions
Chronic pain is one of the most researched areas in modern medicine, with strong evidence supporting multimodal care. No single intervention is sufficient; physical, psychological, and social factors all contribute to how pain persists and how it can be addressed.
When to seek urgent assessmentSome changes in chronic pain require prompt professional evaluation to rule out new or serious causes.
A new pattern of pain, sudden escalation, or pain accompanied by unexplained weight loss, fever, or neurological changes should be assessed promptly — these may indicate a new underlying condition unrelated to existing chronic pain. Do not assume all worsening pain is part of an established pattern without professional review.
What the evidence supportsExercise, pain education, and psychological therapies have the strongest evidence for chronic primary pain.
Exercise therapy is the most broadly supported intervention across chronic pain conditions. Pain neuroscience education reduces pain intensity and unhelpful thought patterns. Psychological approaches — including CBT, ACT, and mindfulness-based pain management — address the cognitive and emotional factors that maintain pain. Medications show limited benefit for chronic primary pain on average across populations; individual decisions about any medication should always be made with a prescriber.
Important safety considerationsSome common responses to chronic pain — including rest and certain medications — can make things worse over time.
Long-term opioid use for chronic primary pain is not evidence-supported and carries significant risk; specialist review is required before or during any opioid therapy. Prolonged bed rest and activity avoidance worsen chronic pain through deconditioning and increased nervous system sensitivity. Staying gently active, within individual limits, is generally recommended.
How chronic pain is understood clinicallyChronic pain involves real changes in how the nervous system processes signals — it is not simply ongoing tissue damage.
The ICD-11 distinguishes chronic primary pain (where pain itself is the condition) from chronic secondary pain (persisting from another cause). Central sensitisation — where the nervous system amplifies pain signals — explains why pain can persist and spread beyond an original injury. This understanding underpins why psychological and lifestyle factors are treated as core, not optional, parts of care.
Complementary approaches with evidenceSeveral complementary approaches are accessible options that sit alongside conventional care for chronic pain.
Acupuncture is recognised in some clinical guidelines for specific chronic pain subtypes, and multiple systematic reviews suggest modest benefits; guidance varies by condition and setting. Yoga, tai chi, and qigong offer movement-based entry points that many seekers find accessible alongside conventional care. Mindfulness-based pain management, developed specifically for chronic pain, provides structured skills for relating differently to persistent pain signals.
Building a care approachEffective chronic pain management typically combines professional guidance with self-management strategies.
Multidisciplinary pain programmes — combining physical, psychological, and educational components — are recommended for chronic primary pain given its biopsychosocial complexity. Self-management skills, including pacing, movement, and stress regulation, are central to long-term outcomes. A multidisciplinary pain clinic team is well placed to address the interacting physical, psychological, and social dimensions that maintain chronic primary pain.
