So a few months ago i took a pretty nasty fall on my skates and smashed my knee on the concrete pretty damn hard, it's been a few months now like i said and it still has not gotten much better. It is really numb most of the time and when i press down hard on it it feels kind of like there's little bumps on it, it hurts like a mother when it gets hit with any amount of force and just overall feels pretty fucked up. Does anyone have any idea what it might be?
