Chronic Neck Pain — Cervical Spondylosis, Causes & Treatment Guide — Symptoms, Causes & Treatment | MyMedicPlus

Chronic neck pain is defined as pain in the cervical spine region persisting for over 3 months. It is the 4th leading cause of disability globally, with a point prevalence of approximately 30% in adults. Like chronic low back pain, neck pain has a biopsychosocial model — anatomical pathology (disc degeneration, osteophytes, facet joint arthritis), nervous system sensitisation, and psychosocial factors (anxiety, depression, fear-avoidance, poor ergonomics) all contribute. Cervical spondylosis (degenerative changes in the cervical spine) is the most common underlying condition. Neck pain can be purely axial (localised to the neck) or radicular (radiating into the arm — cervical radiculopathy). The significant contribution of psychosocial factors — anxiety, depression, poor pain coping strategies, and low self-efficacy — to the development and perpetuation of chronic neck pain means that successful management frequently requires an integrated biopsychosocial approach rather than purely anatomical or biomechanical interventions alone.

Mechanical/degenerative: cervical spondylosis (disc degeneration, loss of disc height, osteophyte formation, facet joint arthropathy — normal ageing, accelerated by previous injury or heavy manual work); cervical disc herniation (protruding disc compresses nerve root — causing arm pain, numbness, weakness); whiplash-associated disorder (WAD — following rear-end vehicle collision, often with chronic pain and disability); sustained poor posture (desk work, smartphone use — 'text neck'); and muscle overuse or tension (trapezius and levator scapulae). Inflammatory: rheumatoid arthritis (atlanto-axial instability — potentially dangerous), ankylosing spondylitis. Serious causes ('red flags'): fracture (trauma), metastatic disease (malignancy), infection (discitis, epidural abscess), polymyalgia rheumatica. Psychological stressors and adverse work-related factors, including low job control, high job demands, and monotonous repetitive work, are independent and clinically significant risk factors for the development of chronic neck pain and its transition from acute to persistent symptoms.

Axial neck pain: aching, stiffness, and tenderness in the cervical spine, occiput, or trapezius muscles — worsened by prolonged static positions, head turning, and stress. Cervical radiculopathy (arm pain from nerve root compression): unilateral arm pain, numbness, tingling, or weakness in a dermatomal pattern corresponding to the compressed nerve root (C5 — deltoid/arm; C6 — thumb/index finger; C7 — middle finger; C8 — ring/little finger). Cervical myelopathy (spinal cord compression — serious): hand clumsiness (difficulty with buttons, writing), upper and lower limb weakness and spasticity, gait difficulty, bladder dysfunction, and positive Lhermitte's sign (electric shock feeling down the spine on neck flexion).

Clinical assessment identifies the pattern (axial, radicular, or myelopathic) and red flags. Spurling's test (compress the cervical spine in lateral flexion toward the symptomatic side) reproduces radicular symptoms. Neurological examination assesses reflexes, muscle strength, and sensation in each dermatome. MRI cervical spine: gold standard imaging — identifies disc herniation, cord compression, spinal stenosis, myelopathy (T2 signal change in cord), and red flag pathology. Plain X-rays assess alignment, disc space, and foraminal narrowing. CT myelogram: for surgical planning or when MRI is contraindicated. Nerve conduction studies/EMG: for complex radiculopathy or to exclude peripheral nerve entrapment (carpal tunnel syndrome). Psychosocial yellow flags — including fear-avoidance beliefs, pain catastrophising, work-related distress, and comorbid depression — should be routinely screened for in all patients with chronic neck pain, as their presence strongly predicts poor response to purely physical or procedural treatments.

Conservative management (first-line): physiotherapy — cervical strengthening and stabilisation exercises (deep neck flexor training), manual therapy (mobilisation/manipulation — short-term benefit), postural education, and ergonomic advice. Analgesics: paracetamol, NSAIDs (short courses — ibuprofen, naproxen), muscle relaxants (diazepam, methocarbamol — short-term). Soft cervical collar: for acute flare-up only (maximum 2-3 weeks — prolonged use causes muscle weakening). Trigger point injections: local anaesthetic and corticosteroid injections into tender muscle knots — useful for myofascial pain. Cervical epidural steroid injections: short-term relief for cervical radiculopathy refractory to physiotherapy. Radiofrequency ablation: for confirmed facet joint pain. Surgery: anterior cervical discectomy and fusion (ACDF) or cervical disc replacement for severe cervical radiculopathy (arm weakness or persistent pain refractory to 6-12 weeks conservative treatment); urgent posterior decompression or ACDF for cervical myelopathy — delay worsens cord injury.

Inadequately managed chronic neck pain leads to progressive functional disability, sleep disturbance, work incapacity, and significant quality of life impairment. Untreated cervical myelopathy (spinal cord compression) is the most serious complication of cervical spondylosis — progressive cord damage causes worsening spasticity, weakness, and ultimately quadriplegia; surgical decompression should not be delayed. Untreated cervical radiculopathy can cause permanent nerve damage with fixed arm weakness, numbness, and muscle atrophy if compressing lesions are not relieved. Chronic neck pain has a strong association with headache (cervicogenic headache — referred pain from upper cervical segments), depression, anxiety, and sleep disorders.

Workstation ergonomics: position computer monitor at eye level to avoid sustained neck flexion; use an adjustable chair with lumbar and head support; use a headset for prolonged phone calls; take regular breaks (every 30-45 minutes) to stand and move. Smartphone posture: hold phone at eye level to avoid 'text neck' (prolonged neck flexion adds 27-49 kg of force on the cervical spine per degree of flexion). Strengthen cervical and scapular stabilising muscles with a structured exercise programme from a physiotherapist. Sleep with a supportive pillow (keeps cervical spine in neutral position — not too high or too low). Quit smoking (smoking accelerates cervical disc degeneration). Manage stress — psychological stress contributes to neck muscle tension and chronicity.

See a GP for neck pain that persists beyond 6 weeks despite rest and analgesia, or significantly limits daily function. Seek urgent same-day assessment or attend A&E for: neck pain following trauma (road traffic accident, fall, sports injury) — do not move the neck until assessed; neck pain with neurological symptoms — arm weakness, numbness, or loss of hand coordination (possible cervical myelopathy); severe headache of sudden onset ('thunderclap headache') with neck stiffness and fever (possible meningitis); and neck pain with fever, weight loss, or a history of cancer, immunosuppression, or tuberculosis. Arm pain, tingling, or weakness radiating below the elbow warrants GP review within days for assessment of cervical radiculopathy — urgent MRI if progressive neurological deficit.
