I wrecked mine two years ago, going over the handlebars of my mt bike.
It was/is beyond real repair through surgery, so I have the bone stciking up and bad sounds when I lift my right arm. Eventually I'll have to have the end of the bone cut off. Yep do what the doc says, mine was just a bad deal with no good fix, since I was 45 at the time, they said I'll just have to learn to live with it, which sucks, but I can still shoot, so it could be worse.
Good luck!
