My leg is swollen from my knee down to my foot, its about 1/3 bigger than my other leg. I didn't do anything to it that I remember. I felt it when it started and thought nothing of it because if I'm working a lot on my feet my knees will swell, right around the knee cap, then it goes away by the next day. This has been going on for two weeks now, actually it was my knee and my calf, last week it migrated down to my foot. I wasn't able to walk last week, but can now, but the swelling isn't going away, it goes down some over night but then swells right back up. I've tried soaking it in epsome salts and I've tried ice, neither seemed to do anything. I don't see any bite marks either.

No one on the Internet would be crazy to even hazard a guess, or give you a diagnosis, but I will tell you one thing, you had better see a doctor real soon because I don't like the symptoms you are describing. You don't even tell us how old you are, but really doesn't matter. Get yourself to a doctor!

I second what tickle says... if it was me I wouldn't even have to think about what I should do. I'd have been at the doctors office or the emergency room.
