dont feel bad, the same thing happened to me...except that i fell down our wooden stairs onto a stone floor and rolled my ankle badly. i ended up crawling over to my dad (a doctor..yeah he ended up helping, he thought i was faking it- seriously!

)
it swelled up huge, and it wasnt broken. this was like 2 months ago, and its still swollen a bit. basically im still recovering...i recently started to try to run on it, and i htink its ok...just doesnt feel the same

...i hope it goes back to normal..
