Awe Freak, that does truly suck. Start chewing on some of those anti-inflammatries and work on the stuff you've been neglecting for awhile so it can heal. If you persist itll just stay crappy and itll be more frustrating in the long run. Write some songs or sort out your studio or something. Drinks lots of beer. Do whatever it is that men do (I'm not sure what that is...sit around scratching yourself and watching sport on tv...?)
Just think of it as a vacation for your fingers. Hope ya feel better.
