I have had ongoing issues with right shoulder since having revision acromioplasty in April. Had 50% improvement after op but still sometimes get pain on scapula + anterior shoulder. sometimes shoulder snaps and clicks.Surgeon says he thinks may have degree of irratation on long tendon of biceps doing various tasks and its jumping out of bicipital groove, at arthroscopy biceps tendon looked normal and was gliding freely.IS THERE ANY EXERCISES I CAN DO TO IMPROVE THIS? Have been offered tendonesis as last resort.
