I had osgood schlatters disease in the classic location just below the left patella tendon. Very painful at the worst stage. Very painful for months afterwards if bumped. I still have the bone protrusion but it doesn't hurt if bumped amymore.
I haven't even ever called you a prick. I didn't like that guy but it's not my job to control it. I haven't suggested banning anyone either. Just gave them a warning that they were probably getting too close for their own good.
