Probably not telling you anything you didn't already know, but...you should keep that finger bandaged tightly (and I mean, tight) and keep it raised above the elbow until the blood flow stops. Something fun while you're doing that: take a bit of blood and rub it on the insides of your wrists, and walk around having fun playing "Stigmata"! XD

Yeah, if you haven't caught on by now, I'm strange.
