I hurt my left knee grappling with one of our fighters tonight. It folded inward with my heel trapped on the mat, there was a loud snap, and I was writhing on the mat sounding like Ned Flanders screaming. I can walk on it, but I have significant looseness on the inside side of my knee, with tenderness along where the MCL is supposed to be. I am working on getting arrangements made to get it looked at in the next day or so. Hopefully nothing is actually torn, or if there is a tear it is just the MCL. Just venting here, if I complain to anyone besides my wife in real life I will get the "well that's what you get for that stupid fighting stuff, why don't you quit and blah blah blah" speech.
