wow, sexy. i had something similar last year. came off a rail scraped my shin on it. The surface didnt cut, but all the tissue on my shin balled up in a huge clump, then it went away after a couple days... so I thought, really it was just rotting, then my whole lower leg, in one day, swelled so tight that the skin wouldn't stretch any more!
if you can believe it actually fixed itself, i have it drained 3 times by a doctor and 3 cortizone injections all of which did nothing, eventually it just went away and looks fairly normal now, still hurts though if i land on it
