I whacked my elbow a couple of years ago before going to Font.
I didn't hit the nerve though, so not very comprable. I'd have thought that it should be ok once the nerve swelling goes down, but I'm sure a doctow will be along in a minute to offer more qualified advice. I trapped a nerve in my neck once (trying 1-arm lock-offs) 2 week before a trip to nroway. For the whole trip the muscles in my rotator cuff wouldn't work and my shoulder kept subluxing. Once it did it 4 times in one redpoint!
Oh, yeah, the font elbow - the whole area up[ and down fromt he elbow swole up so badly that if I i pressed my finger into the flesh, the dent stayed for about 5 minutes!!! By day four it was agony, with about 50 degress of flexion. I finally went to the hospital when I spent a night hallucinating! They took blood tests, x-rays (
) and rammed my on 3g/day of amoxycillin as I apparently I had septic olecranon bursists!
Still, I managed to tick Helicoptere and nearly got Onde De Choc (must go back for that one). So glad I finally held the swing on that highball, spinning, leg breaking bitch! It really was a multi-year seige with over 50 falls from from the top storey and with my dodgey knee I doubt I'd ever try it again...
I'd say go, but be careful!
