Waiting it out is exactly what my doctor said. He said there is surgeries and manual manipulation and a few other things but he said he has never seen any of them work. The cortisone shots really were a lifesaver for me. He also would not order PT until it was thawing on its own because he said that he never found it to be successful either. But once I started doing PT, it thawed and felt better pretty quick. All told I was in it more than a year, and I still have to be careful of shoulder posture. Do you have an appointment for a shot? Have you ever tried topical nsaids, or topical lidocaine?
