Mine are all football related. (American not everywhere else football)
My fifth grade year I dislocated my thumb catching the ball. My thumb was pointing back at me if I pointed with my pointer finger. Dislocating something in itself doesnt hurt that bad, but if you leve it thee for 7 hours it becomes hell. In 7th grade I torn my PCL, a ligament behind the ACL. It's just as bad as an ACL tear, but it is harder to diagnose. You can go months with a severe limp and be non the wiser.The funny thing is that I continued playing the whole year even though I was practically one-legged.
