The referred pain from the deltoid trigger points is rather unique among myofascial pain patterns in that it “stays close to home” and is not projected to an adjacent region of the body. The pain is typically experienced only during movement of the shoulder joint, and when there is trigger point activity in all three deltoid sections the client may not be able to raise the arm up to 90 degrees. Because the trigger point in the anterior deltoid projects pain to both the anterior and lateral aspects of the shoulder, it will often activate trigger points in the lateral deltoid.
