The levator scapulae muscle is located in the neck. It attaches from the cervical vertebrae to the top of the shoulder blade. It is responsible for elevation of the shoulder and lateral flexion of the neck. This muscle is often overloaded from poor shoulder posture such as holding your shoulders up to your ears when stressed. When this happens trigger points will develop causing pain to be felt along the shoulder blade and into the neck. Trigger points in this muscle are the most common cause of a stiff sore neck.
