Here's a strange bruise I noticed/felt this morning while getting dressed after working out. I'm interesting in hearing random explanations for it, as I have *no* idea where it came from.



It's on my left leg, back outside part of my knee. Swollen, and the central bruise. The bruise is more obvious in the second picture, but the picture itself is a little more blurry. That's my calf to the left, my knee to the top, my thigh to the right.

Any and all explanations, no matter how random, welcome. Have fun with this!
