Healing Is Hot

I fell yesterday - randomly. I was walking outside, in new shoes that I can't even call heels, and I think my ankle just collapsed. Which isn't really that strange, it was the weak one that I sprained years ago and I affectionately call 'my hoof'. Because I was holding things, I landed on my elbow, forearm, and right knee. It didn't hut and thankfully didn't wreak my jeans. However, when I got home I found out I scrapped it up pretty good and it was bleeding (but it didn't go through my pants so I don't really get how that happens.) Anyway, y knee got a little swollen over night and is sore now when I bend it. Hopefully it will turn into a really impressive bruise! The strangest thing though is that the whole knee area, around the scabby part, is very very warm. I know that is how you tell a injury, but it is really strange to feel the difference in temperature between my two knee caps. I can't remember really experiencing that before.
