So I wake up today for work and look down at my ankle and it is black and blue all over and swollen. I can walk on it and there is a tiny bit of pain but only when I put a lot of weight on it. Appearently like 2 days ago my girlfriend said "oh my god what happened to your ankle" while I was playing Grand Theft Auto IV and I responded with "I don't know it has been hurting a little" and I didn't bother to look down and see what she was talking about because I was playing Grand Theft Auto IV. So I show it to her today and she is like "yeah I told you the other day and you jsut said it hurt."

It can't be broken because I am walking on it but it is red/black/blue on both sides. I figure with guys like ertrauma on here someone might have some idea of what is wrong. Any ideas?
