OK, so I was actually in BJJ sparring and for some stupid reason I decided to kick my partner in the leg and I believe it connected with his knee. (actually I was going for a drop seo nagi, and trying to spread his base out) This was last sunday. So two hours after it happens, I get a knot on my shin he size of a baseball. This subsides but now my entire front shin and side of calf is black and blue and I have a knot in my leg that is yellow. I figure its a bruise and will go away with time, but it hasn't really changed except the knot is smaller. I figured I would ask in the standup forum because I am sure it has happened to some other people. Any suggestions or opinions? I figure I'll wait another week and go to a dr. if it doesn't go away.
