Hi, i'm 17 and i play quarterback, i had an MRI done on my shoulder yesterday because of an on going problem. About six weeks ago i noticed a popping sound and weakness in my shoulder, this was accompanied slight pain. I have complete external rotation and use my shoulder as normal, for everything (so my rotator cuff is fine), except, the thing is when i go to throw a football, my shoulder feels like its catching and it gets tired fast. and sore, is it possible i have damaged my labrum, and if so with and otherwise healthy shoulder, what are the chance of a full recovery? is it just possible ive done something else?
