I had total shoulder replacement mid october, now three months have large issue....went to therapy, 5 times, think something happened, went back to my doctor, he took ct scan X-rays says he cannot find anything,but it could be torn. What it looks like, is that the glenoid (component), some how dropped , it moved and it sticks out toward my chest, and you can see a screw or something in front. The doctor says hes not worried about it, just my mobility. How can I exercise, the touching of it really hurts....I left his office in tears, I don't know where to turn, or what to do....can you help?
