Chronic and Persistent Pain Conditions
Framework
Chronic pain persists beyond typical healing time, usually more than 3 months, and is best understood through a biopsychosocial model. Central sensitization, nociplastic mechanisms, sleep disruption, depression, anxiety, trauma history, and social context all influence the experience. Conditions such as fibromyalgia, chronic low back pain, migraine, and complex regional pain syndrome require multimodal care: physical therapy and graded activity, cognitive behavioral therapy, pain neuroscience education, sleep and mood treatment, and targeted medications such as SNRIs, gabapentinoids, or TCAs.
Long-term opioid therapy
Benefits are modest and risks accumulate: tolerance, opioid-induced hyperalgesia, hypogonadism, immune and sleep effects, falls, constipation, and overdose - especially with concurrent benzodiazepines. Safe practice includes functional goals, the lowest effective dose, a prescription drug monitoring program check, urine drug testing, a written agreement, and co-prescribing naloxone. Taper slowly in patients on long-term therapy (commonly around 10% per month) and never abruptly.
Teaching self-management
Help patients build a flare plan, pace activity, set realistic goals, and understand that a pain score of zero is not the target. Acknowledge the pain is real while focusing on function and coping.
Traps
Do not mistake withdrawal or inadequately treated pain for addiction, and do not label a patient "drug seeking" in the record. Do not expect cure, and do not dismiss the report because imaging is normal. Screen for depression, sleep apnea, and substance use disorder, which change the risk-benefit calculus.
Rule of thumb: document function - "walked to the mailbox," "slept 5 hours" - rather than a number alone; function is the outcome that matters in chronic pain.
