I went to a shoulder specialist in Atlanta who had treated baseball teams. I thought it was a rotator cuff injury from my old baseball days and all the golf I had played. After examining me, he told me my shoulder was structurally sound. Then I asked him what was causing my pain and he said probably from the arthritis thar is there. He gave me 6 exercises to do with a band and Meloxicam and if I had pain after 6 weeks, come back and he would give me an injection. I never had to go back, been ~ 6 years. I can email you a copy of the sheet with the exercises if you message me your email.
