Wow, that sucks. I've never been seriously injured like that. The most hurting I'm getting right now are a bunch of blood blisters on my fingers from drumming all day. Yeah, I'm a drummer. We were just screwing around too. Just playing the first thing that came to mind and it all sounded great. We kept going for about half an hour without a break and it was beautiful. The best part was, That Girl I Like was watching and I think she was pretty impressed. =P
Yeah the injury thing sucks. I can skateboard some but I'm really not supposed to.
I'm a (fairly new) guitar player myself. I've been playing since my 17th birthday (when I got my guitar) and I've had a fair amount of time to do so because I've been hurt since like January.
