well, sliding into third in a tight game of baseball during my portfolio class, my back leg seemed to get kinda caught up and twisted underneath myself. The end result was a distinct popping feeling, a locking period of a few seconds of intense pain, and then another popping feeling and the pain subsiding a bitsy.
now it is super stiff and I can't twist it the way I over extended it.
1. what did I do?
2. how can i fix it.
