Re: broken wrist
Ha! You too? (sorry, I know it's a bummer)
I broke my wrist about a month ago, one of them little roundy bones in there somewhere ... don't remember which one. But. I didn't need a cast and have been drumming on it since about a week after it happened. I guess I was lucky. Actually, the arm I broke about a month before that was about as devastating - which is to say not at all! It didn't need a cast either and I've been drumming on it, too.
Maybe your damage was worse (sounds like it if you need a cast), and I'm no doctor, but I suspect that after a little down time to heal and working yourself back into it slowly enough to avoid pain and reinjury and you'll be as good as new.
