What would cause your legs to become swollen and hot?

[GingerSnaps]

My whole left side becomes numb at times and over the last several months my leg gets real hot and swollen. In the past few months when I am sitting in class my leg feels like it is tingling and it drives me nuts because I keep shifting in my seat and I know that people are noticing that something is out of place. It's kind of like your leg falls asleep but it isn't and it's hard to explain.

If you have ever had a test for a heat attack it feels like the needle that they run through your arteries and it feels weird which is kind of like tickling you and a sharp pain at the same time.

I hate Doctors so I don't go to them. I think that I might have to see one about this because I can't stand the amount of heat that is in my leg.
