Conditions such as dystonia, when the muscles contract involuntarily, affect the hands and neck but also various parts of the body, according to Mayo Clinic. The twitching begins in a single area, such as the hand or neck, and typically occurs during a specific action, such as handwriting. Twitching often worsens when the patient is experiencing fatigue, stress or anxiety, and may become more noticeable over time.
Neck twitching caused by diseases of the nervous system cause the neck to pull forward or backward and twist and turn to one side. The neck and hand muscles are affected by contractions and spasms that may cause pain or embarrassment, according to Mayo Clinic.
Tic disorders that cause twitching in isolated muscle movements are also known as myoclonic jerks, according to WebMD. The twitching in the hands and neck may be caused by side effects of medication or underlying diseases such as Parkinson's or cerebral palsy. Sleep deprivation and stress may cause the twitching to worsen over time.Learn more about Conditions & Diseases
