My son experienced intermittent shoulder pain over a period of a year in HS. He saw an ortho multiple times, each time he was told it was not a labrum tear. It was very concerning and frustrating. Turns out it was impingement. We found a physical therapist who identified a specific area of his shoulder that lacked flexibility and he worked it out with specific stretches. Maintaining his shoulder flexibility has become a lifestyle that he has to address continually.
