I was rolling yesterday and during a scramble my sparring partner came down with his knee on my index finger. It hurt, but I didn't think too much of it at the time and finished the roll and several more before class ended. When I got home though, my finger was throbbing quite a bit and as of this morning has swollen up a bit. I can stretch the finger our or bend it. Does anyone have any tips that might help me get the swelling down so I can go to class tomorrow without being incapacitated? Will freezing help? Compression? I'm a little clueless.
