Did the very same thing 4 years or so back, slammed doing a (somewhat lubricated, I admit) hill bomb in Edinburgh and took most of the skin off my arm too, along with a big chunk north of my elbow where I could see the fatty tissue seeping out, like a kind of yellow cottage cheese. Yum. Despite sharing a flat with a doctor, she was too pished to diagnose it, so constructed a dressing from hemming fabric and Woolworth's budget Sellotape. Slept on it that night (and the doctor's mate, also a doctor, there's a theme here) but woke up and and realised I had to go to casualty. Plaster up to the elbow and express instructions not to overdo it, since like lynx and madillness say above, you could fuck blood supply to your thumb up good and proper. Still, you can skate with a stookey on. Even write "JAMIE THOMAS IZ GOD" on it in biro if you like, but take 'er easy as they say.
