i broke mine in 8th grade skateboarding. they couldn't re-set it so it healed like naz was talking about with the bump. i had to stay in this brace that was kind of like two backpack straps that pulled my shoulders back for two weeks and was back swimming/training about two months later.

i had to do regular stretches and light weights before i got my full range of motion back, but i think you should be fine.
