Have you tried warm waxing your hands? A friend who is a guitar player has the same situation and he uses the wax treatment, works for him.
My guess is that you will have to use the "intractable pain" approach , if your doctor is cool then you might be able to convince him that Cannabis is your preferred way of dealing with this pain , instead of having him prescribe pain pills. IF your doctor does not go along then you need to document your ailment ,X-rays,MRI, doctors notes, and take that medical record to one of the clinics, like Sentry,THC clinic, and they will help you. Good luck.:smokin:
