Hi, lately i have been having a problem. for a while now i have had a problem with jerking my head and/or shoulders. when this happens i normally get a chill down my spine. all these problems i'm dealing with are painless. can someone help me?

Doctor can evaluate: One who makes repeated twitches, jerks, noises, or rolls his eyes, may have tics, which are exaggerated habits. Of course, she might have a tight muscle or some irritation in the neck or shoulders that "encourage" tics to continue because irritation makes her sense there is some discomfort. Her primary care doctor can do a full exam to see what the diagnosis and next step may be.
