A description of where a Myofascial Trigger Point may produce pain in the body.  This area is generally located away from the trigger point.

Pain arising from TrPs in this muscle is usually felt as a deep ache under the upper portion of the scapula.  Pain is also felt over the posterior (back) of the deltoid muscle and spills down the back of the arm and into the elbow.  The pain occasionally includes the ulnar (pinky) side of the forearm and pinky finger.
