So I wiped out in today's cross race. I was at the top of a run-up and bam! next thing I know I'm on my left side. My knee hurt but I got back on the bike thinking I could ride it off. Nope- about 300m later I could only pedal with my right leg. I pulled out of the race needless to say.

Now it's swollen, painful and I can't bend it much. Besides R-I-C-E what else can I do?
