I was playing basketball and I drove to the basket, had a mid air collision then smacked my elbow on to the floor hardly. I couldn't move it for a second there cuz I thought I dislocated it, but thank god that it was okay I sank 1/2 free throws then never came back t the game again. after that, whenever I move it it will hurt but now, it's kinda okay w/ mild pain on it. what can it be?
