Sometimes the muscles in the neck can start to contract involuntarily. These contractions are often painful.

The first course of action if neck muscle contractions appear is always to consult a doctor.

Please see our disclaimer below.

Sometimes a doctor may not know what is causing the problem or prescribes treatments that do not seem to work. This is understandable, as muscle contractions have a wide range of causes and no General Practitioner (GP) can know all of them.

In this case, one possible cause is a neck dystonia (the medical term for this is Spasmodic Torticollis or Cervical Dystonia). The symptoms of neck dystonia vary and may be one or more of the following:

  1. The feeling that the neck/head is being pulled to one side.
  2. Alternatively, the neck/head feels as if it is being pulled backwards or forwards.
  3. Painful muscle spasms or stiffness in the neck.
  4. As a result, abnormal posture with the neck/head being held at an angle.
  5. Difficulty turning the neck/head one way with relative ease turning the neck the other way.

Some examples of involuntary head positions caused by neck dystonia are shown below:

Neck dystonia commonly appears in people between the ages of 30 and 50 but does sometimes affect younger people. It is one form of dystonia – a condition that causes uncontrollable and often painful muscle contractions believed to be as a result of incorrect messages from the brain to the muscles.

Dystonia is a neurological movement disorder and, if the symptoms listed above appear, the correct course of action is for a GP to make a referral to a neurologist specialising in movement disorders. There are treatments for neck dystonia that can significantly reduce the symptoms in the majority of cases.  

If you would like a leaflet; or more information on neck dystonia please click here or call our helpline on 020 7793 3650.

Only a specialist neurologist has the knowledge and skill to diagnose and treat neck dystonia.  If the patient and their GP agree that the symptoms might possibly indicate neck dystonia then the GP should refer the patient to such a specialist.
