Hey Dave, that sucks for you! I know how it is though, believe me. I've had more days of injuries and illnesses than not. I was on crutches at one point, as well. That was when I was at school--try going up and down crowded flights of concrete stairs every 40 minutes for a few weeks! The crutches aren't too hard to get the hang of if they're set to the right height.
If you need some guitar-related websites, maybe we can add a bunch in this thread? I can't say that I visit many at all these days. Depending on what level you're at you find find something interesting at
Chops From Hell (read the online columns).
Buy a couple of instructional DVDs too. Sit on the lounge and play along; it's kinda like jamming. Sorta. In a sad, loney way. ;)
