I wrestled for 11 years and battled injuries my whole career. Three years in a row I ended my freestyle and greco season with injuries. Torn rotator cuff at a tournament where I qualified for the national team, the next year I pulled muscles in my back, and then tore my mcl in my knee. This high school season I was having knee problems that cost me a couple of weeks and when I finally came back I pulled my quad where I was out for about 3 weeks, I came back a little early so I could get a qualifying weight in at a 140lbs, in the last match of the year.
I wrestled this post season with a stress fracture in my foot and I injured my back in the first match at state.
You don't really feel the pain in a big match but you sure as hell do after the match.
Its part of the sport
