Jammed my finger.

[Jason1]

So I was playing catch today at work with a football, and went in to catch a low pass and didnt catch it, instead jammed the hell out of my middle finger. I was with all the guys so I acted like it wasnt that bad, but it hurt like hell. A little while later I noticed it was starting to swell up, although it didnt seem to hurt as much. A few hours after that, its even bigger, and now its horribly painful, I can barley bend it now. Im going to the doctor tomorrow since my mom works there anyways, but has anyone ever done something like this? Its jammed on the middle part of my finger, so the joint near the nail is fine, but then past that it really starts to swell up.
