Ankle Problems

So, yesterday while I was at work, I slipped and twisted my ankle. Luckily, it was at the end of my shift, but I went to Wal-Mart after work and walked around in relative pain for an hour and a half. When I got home, Tom looked at it and said it was all swollen, and that I'd probably done something to it. This is it today.

I went to the hospital and got an x-ray. They said there was no fracture, but now I have off from work until Thursday. What to do with my free time...
