I have chronic bilateral rotator cuff syndrome (among numerous other joint involvements) related to my enteropathic arthritis. PT never helped much, I suppose because this is not an acute injury, but an inflammatory process. Mostly, it is my medications that help (sulfasalazine, biologics, pain medications, and muscle relaxers). Also, daily range of motion and stretching is important. All this is managed by my rheumatologist.
