Cervical dystonia is a neurological condition characterized by excessive pulling of the muscles of the neck and shoulder resulting in abnormal movements of the head (dystonia). Most commonly, the head turns to one side or the other. Tilting sideways, or to the back or front may also occur. The turning or tilting movements may be accompanied by shaking movement (tremor) and/or soreness of the muscles of the neck and shoulders. Cervical dystonia can occur at any age, but most cases occur in middle age. The cause of Cervical dystonia is often unknown
