Cervical dystonia is a neurological disorder that causes involuntary muscle contractions in the neck, leading to abnormal head positions and movements. This condition can result in discomfort and pain, as the muscles may pull the head to one side or cause it to tilt forward or backward. The exact cause of cervical dystonia is often unknown, but it may be linked to genetic factors or previous injuries. Treatment options include physical therapy, medications, and in some cases, botulinum toxin injections to help relax the affected muscles.
