Clinical Assessment and Management of Chronic Pain

Chronic pain is a complex, multifactorial condition that persists beyond normal tissue healing and affects physical, emotional and social well-being. Its assessment begins with a detailed clinical history, encompassing pain onset, location, quality, intensity and factors that exacerbate or relieve symptoms. Physical examination focuses on functional impairment, neurological signs and musculoskeletal abnormalities, often supplemented by imaging or laboratory tests to exclude specific pathologies. Standardised scales such as numerical rating scales, pain diaries and questionnaires capture intensity and interference with daily activities, while emerging digital tools enable continuous monitoring of symptoms in real time. Quantitative sensory testing and psychological screening further characterise sensory profiles and comorbid mood disorders, guiding personalised management.

Management is inherently multidisciplinary. Pharmacological treatments range from non-steroidal anti-inflammatories and antidepressants to anticonvulsants and opioids, selected according to pain mechanism and patient comorbidities. Non-pharmacological approaches include physical therapy, cognitive-behavioural interventions, mindfulness and patient education, which address biomechanical dysfunction and maladaptive coping. Interventional techniques—such as nerve blocks, spinal cord stimulation and radiofrequency ablation—offer targeted relief for selected neuropathic or nociceptive syndromes. Self-management strategies, peer support and digital health applications enhance adherence and empower patients. The overarching goal is functional restoration, reduction of analgesic burden and improvement of quality of life through an integrated, individualised care plan.

Technical terms

Chronic pain: Persistent or recurrent pain lasting longer than three months, often without a clear healing timeline.

Ecological momentary assessment (EMA): A research method that captures real-time self-reports of symptoms and behaviours in a patient’s natural environment.

Endotype: A subgroup of patients defined by a distinct underlying pathophysiological or symptom pattern, useful for personalising treatment.

Numerical Rating Scale (NRS): A patient-reported measure of pain intensity ranging from 0 (no pain) to 10 (worst possible pain).

Proof-of-concept trial: An early-phase clinical study designed to provide initial evidence of efficacy and inform the design of larger trials.
