Read COVID-19 guidance from NICE

Treatment of almost all medical conditions has been affected by the COVID-19 pandemic. NICE has issued rapid update guidelines in relation to many of these. This guidance is changing frequently. Please visit to see if there is temporary guidance issued by NICE in relation to the management of this condition, which may vary from the information given below.

The intervertebral discs lie between adjacent vertebrae. They consist of a peripheral fibrocartilaginous part called the annulus fibrosus and a central semifluid/gelatinous part called the nucleus pulposus.

  • There is no disc between C1 and C2 (atlas and axis), and only ligaments and joint capsules limit excessive motion.
  • Disc degeneration or herniation can injure the spinal cord or nerve roots.
  • Cervical radiculopathy is compression or injury to a nerve root in the cervical spine. Its most common causes are cervical disc herniation and degenerative disease.[1]
  • The term myelopathy is used to describe any neurological deficit related to the spinal cord itself. Myelopathy may be due to compression of the spinal cord by a prolapsed cervical disc.

Neck pain is one of the most common musculoskeletal disorders, having a global age-standardised prevalence rate of 27.0 per 1,000 population. Psychological risk factors, such as long-term stress, lack of social support, anxiety, and depression are important risk factors for neck pain.[2]

See the separate Neck Pain (Cervicalgia) and Torticollis, Cervical Spondylosis, Whiplash and Cervical Spine Injury and Spinal Cord Injury and Compression articles.

Cervical disc disorders can include:

Disc herniation (prolapsed intervertebral disc)

  • The nucleus pulposus bulges or breaks through the annulus of the disc.
  • Cervical disc disorder may occur from a single whiplash injury but repetitive injuries are more common.
  • Cervical disc herniation occurs most frequently at the levels of C4/5, C5/6 and C6/7.
  • Posterior herniation causes symptoms by compressing the cord or a nerve root, or by stretching the posterior longitudinal ligament or posterior annulus.

Degenerative disc disease (cervical spondylosis)

  • The exact cause of this cervical disc disorder is not known. Some suggest that it is a natural part of ageing; however, disc degeneration can also occur in young people. The cause is likely to be multifactorial, including genetic, environmental, traumatic, inflammatory, infectious and other factors.
  • Annular tears, internal disc disruption and resorption, disc space narrowing, disc fibrosis and osteophyte formation can all occur.
  • Degenerative disc disease may lead to disc herniation.
  • See the separate Cervical Spondylosis article

Internal disc disruption

  • This includes damage to the disc without external deformity.
  • It may result from whiplash or other trauma to the neck.
  • Degenerative disc disease can progress to internal disc disruption.
  • See the separate Whiplash and Cervical Spine Injury article.

Infection (discitis)

See also the separate Examination of the Spine article. During assessment of a patient with neck pain, always be alert to red flag symptoms or signs.

Red flags for neck pain[1]

  • Malignancy, infection, or inflammation:
    • Fever, night sweats, unexplained weight loss.
    • Excruciating pain, cervical lymphadenopathy, intractable night pain, pain that is increasing, exquisite tenderness over vertebral body, generalised neck stiffness.
    • Nausea or vomiting.
    • New or severe headache.
    • Photophobia or phonophobia.
    • Visual loss.
    • Skin erythema, wounds or exudate.
  • Cervical myelopathy
    • Paresis.
    • Sensory changes or loss of sensation.
    • Altered muscle tone.
    • Clumsy or weak hands.
    • Gait disturbance.
    • Babinski's sign: up-going plantar reflex, hyper-reflexia, clonus, spasticity.
    • Hoffman's sign.
    • Lhermitte's sign: flexion of the neck causes an electric shock-type sensation that radiates down the spine and into the limbs.
    • More severe symptoms may include profound weakness of the hands, bowel or bladder dysfunction, and severe gait ataxia. Rarely there is loss of proximal muscle strength in the arms or legs.
  • Other neurological signs and symptoms:
    • Altered cognitive state.
    • Weakness involving more than one myotome or loss of sensation involving more than one dermatome.
  • New symptoms before the age of 20 years or after the age of 55 years.
  • Age-related factors for people aged over 50 years:
    • History of cancer.
    • Vascular disease.
  • Other red flag features include:
    • History of inflammatory arthritis, cancer, tuberculosis, immunosuppression, drug abuse, AIDS, or other infections.
    • History of violent trauma (eg road traffic accident) or a fall from a height; minor trauma in a person at risk of osteoporosis (especially in post–menopausal women). Minor trauma may fracture the spine in people with osteoporosis.
    • History of neck surgery.


  • If there was an injury, note the time since the injury and the mechanism.
  • Ask about the pain:
    • Note the distribution. Neck pain can radiate to an upper limb. Pain is usually unilateral but it may be bilateral. Pain can disturb sleep. Neck pain is frequently absent in radiculopathy.
    • Ask about speed of onset. Insidious onset of symptoms is usual in cervical radiculopathy but it may be abrupt in acute injury.
    • Pain from the disc without nerve root involvement is typically vague, diffuse and distributed axially.
    • Activities that raise pressure in the disc, such as lifting or a Valsalva manoeuvre, will exacerbate symptoms. Lying down decreases pressure in the disc and eases pain.
    • Driving causes vibration that aggravates disc pain.
  • Make a systematic enquiry about general health. Fever suggests infection. Unintentional weight loss suggests malignancy.


  • If pain originates from the disc but there is no nerve root involvement, there will be normal neurological examination.
  • Tenderness with movement in the posteroanterior plane may suggest disc pathology.
  • Signs of radiculopathy on examination:
    • The neck will show a decreased range of movement. This is very common with pain and spasm from any cause.
    • Extension and rotation increase pain. In Spurling's manoeuvre, the patient's neck is extended, bent laterally and held down. It elicits radicular symptoms.
    • In the abduction sign, pain improves when the neck is flexed or on abduction of the affected arm over the top of the head.
    • Upper limb weakness, paraesthesia, dermatomal sensory deficit and changes to reflexes can occur as outlined in the table below.[1]
    • A herniated disc can also produce thermal changes (thermatomes) in specific distributions.

  • Signs of myelopathy on examination:
    • Increased upper and lower limb reflexes or other upper motor neurone signs suggest myelopathy.
    • Upper motor neurone signs include:
      • Weakness.
      • Spasticity.
      • Hyperreflexia.
      • Positive Babinski's sign (up-going plantars).
      • Clonus.
      • Positive Hoffman's reflex (flicking a finger causes adjacent fingers to flex).
    • Sphincter disturbances are late features of cervical and thoracic cord compression.
    • Cervical spine lesions can produce quadriplegia.
    • Urgent evaluation and action are needed.

Neck pain with radiculopathy and no red flag features usually does not require imaging studies or other special investigations, as it is likely to be self-limiting.[1] Immediate admission and decompression are required for myelopathy (spinal cord compression).

  • Blood tests may be guided by suggestions of other rheumatological pathology:
    • FBC may show anaemia of chronic disease or evidence of infection.
    • Elevated ESR is nonspecific but suggests an inflammatory process.
    • Rheumatoid factor should be requested if rheumatoid arthritis is considered and HLA-B27 may indicate ankylosing spondylitis.
  • Imaging studies are important but they should be interpreted in the light of the clinical picture, as positive findings are quite common in people without any complaints:
    • Plain X-ray of the cervical spine may be used to evaluate chronic degenerative changes, metastatic disease, infection, spinal deformity, and stability. Interpretation is difficult because degenerative features are almost universal over the age of 35 years.
    • An MRI scan may be indicated if X-rays show no significant abnormality but symptoms are continuing. MRI should be performed to assess for an intervertebral disc herniation, with or without compressive or spondylotic osteophytes.[7]
    • CT myelography may be considered if there are any contra-indications to MRI.[7]
  • Electromyography may be helpful if it is unclear whether the patient has cervical radiculopathy or a nerve entrapment syndrome in the upper extremity.[8]
  • Look for and treat any comorbidity.
  • Drug treatment:
    • Analgesia may relieve pain and help muscle spasm.
    • If pain is chronic and severe, analgesia may be enhanced by the addition of amitriptyline or gabapentin.
    • Diazepam for 3-7 days may be useful for people with severe muscle spasm.
  • Early mobilisation is important.
  • Physiotherapy including stabilisation exercises and posture training may be valuable.
  • Heat and massage may relieve muscle spasm.
  • Neck supports should be used for as short a time as possible (ie 2-4 days) and under supervision.
  • There is insufficient evidence to recommend manual therapies such as manipulation.
  • Surgery:
    • The finding of a disc lesion does not mean that surgery is indicated and in most cases conservative management is all that is needed. There may be spontaneous regression of a herniated disc.[9]
    • If there are significant neurological abnormalities such as upper motor neurone signs in the limbs or bladder disturbance, surgical decompression is indicated.
    • Surgery may also be indicated in intractable pain.
  • If an intervertebral disc compresses the spinal cord, it can produce myelopathy with weakness, hyperreflexia and neurogenic bowel and bladder dysfunction. There may be associated significant upper limb weakness or numbness as well as pain.
  • Beware of missing serious underlying disease, including malignancy, infections producing abscesses and inflammatory conditions. Always be alert to red flags.
  • Most cases of acute neck pain resolve within two months. However, half of people continue to experience low-grade symptoms or recurrences for more than a year.[1]
  • The prognosis for cervical radiculopathy is favourable: symptoms resolve in most people and without surgical treatment.[7]
  • Surgery also has good results but is indicated in only a minority. It is likely that the attitude of the patient to active rehabilitation is very important for a good result. However, the general prognosis for neck pain is not good and it is often chronic and persistent.
