I'm aware of the risk, since I already had one shot (~3mo after the injury, but I wasnt doing PT at the time, injury was in April '04, but I didnt start PT until Sept '05) the ortho said he'll only give one more to that shoulder when we talked surgery or shots during my last visit in January. The plan he laid out was if I didnt improve, we'll do a shot, wait 3-4mo to see if it works, and then do surgery.
I recently noticed my left shoulder "catching" 1-3 times a week (right shoulder was the original injury and will catch 1-3 times a day, if I force the arm through that range of motion then I'm good for several hours, also occasional popping noises), so I'm not sure what's up with that, another topic to discuss with the ortho at my next visit. I'm wondering if it could be a nerve impingment or something in my neck.
