I had a separated shoulder years ago and had surgery. Screw installed. It initially lifted out and then finally settled in and the shoulder healed when wrapped tightly. Took six months before I could raise my arm enough to turn out the overhead lights in my van. Another buddy didn't have the surgery and his shoulder hangs down and is very unstable. He wishes he had the other surgery. Others I know have left it as is and have had no further problems other than the bump. Very common hockey injury. Good luck with it.
