I am in an advanced movement class for theatre. we do acrobatics, tumbling, aerial silks and stationary trapeze. today i was doing a shoulder roll and landed on it funny. it was extremely painful, but i'm not a stranger to small injuries, so i pushed through. all day it would bug me, but now i am trying to sleep and am unable to get even slightly comfortable with the pain persisting. i get sharp pain nearly every time i move it more than an inch. it is tender to the touch on the top near my clavicle especially. I need my shoulder for performing, but don;t want to permanently damage it. in short, what should i do?
