Nature

Torticollis, also known as wry neck, is a painful, dystonic condition defined by an abnormal, asymmetrical head or neck position, which may be due to a variety of causes. The term torticollis is derived from the Latin words tortus, meaning "twisted", and collum, meaning "neck".

The most common case has no obvious cause, and the pain and difficulty with turning the head usually goes away after a few days, even without treatment in adults.
