Hi, I'm 15 and yesterday I was at volleyball. We had to run 2 miles on the football field. I don't run very much so I think that could be an issue. After I ran I kept feeling a sharp pain when I would walk. On the inside upper part of my thigh. Almost at the ball and socket point. I dont know if I pulled something or what happened. I have practice again today and I dont know what to do. Help!?
