Torticollis, or wry neck, is a twisted neck. Acute torticollis is thought to be due to minor local musculoskeletal irritation causing pain and spasm in neck muscles [1]. Although acquired torticollis is one of the most common forms of dystonia, it remains a rare disorder. Prevalence has been estimated at 1 in 10,000 to 1 in 20,000 people in the general population [2].
