In reply to taddersandbadger:
I've lost no range of motion at all, though I had done quite a lot of shoulder range of motion and control exercises for general health before the accident. Strength is pretty much back at pre-injury levels. I got my full range back in a few weeks, started weight training at about 8 weeks and returned to climbing 12 weeks post-op.
I get occasional aches, but nothing serious, and nothing that gets in the way of anything. I don't need to take any analgesics.
Of course, your case is different as yours is a chronic condition, and again, I don't know the specifics, but I think you've got room for optimism
