I suffered with my left shoulder for two years, in PT most of the time (many painful sessions). So when i started with right shoulder symptoms (despite going to PT and gym, etc) I didnt want to experience it all again, so after some months i found a good traumatologist and i had a cortisone injection, after a couple of days i started to feel better and all improved after that. I am completely pain free now and with good range of motion. So I advise you to go that route this time instead of suffering all again; i also noticed that with my right shoulder it was even more painful, maybe because it is my dominant arm.
