Eric - PATENIENCE! My youngest was on the wrong end of a bicycle/SUV collision about 2 years ago; the brain suregery, pinned collarbone, broken ribs, etc., have, thankfully, all healed completely. The only lingering problem is with the dislocated extensor tendon on his left middle finger - he couldn't stand not playing, and started picking his guitar before he was ready. The surgery didn't heal quite right, and now he has pain when he plays - not enough to keep him from playing, but he's worried he might not be able to keep it up his whole life. Fingers are key; let it heal! Your instruments will still be there when it's ready. (Of course, we're kind of glad his brain healed, too. Apparently the memory recovery was kind of trippy - he told me I'll take a CD that I know I knew inside out before, and I can't remember any of it. I'll put it on and after 2 or 3 notes the whole thing comes back at once. It's f***in' WEIRD!)
