I had this same thing with my right shoulder in Feb. 2001 and that shot only helped me feel better for about 7 days. After that, I was in interminable pain, thus surgery was necessary to correct the disfigured acromion.
My doc compared my right shoulder x-ray from 2001 with my left one from today and it was easy to see why the left took so much longer to cause me pain. While the hook is there, it's only about 3/4 the size of the hook that was on my right acromion. With the history I've had with the right, I'm not banking too much on the shot and PT working. Maybe that's the wrong attitude to take, but I'd really prefer to just have the surgery, get the bone re-shaped so I can get back in the gym and KNOW that I won't have these problems anymore.
Either way, this whole thing still sucks swamp water...
