I will put in a word for acupuncture as well. I have serious problems from years of keeping a heavy slide on the little finger whilst shaping full chords in standard tuning. My acupuncturist is also a GP and the combined orthodox/alternative approach is what has kept me functioning for years. I also have proper sports physio hand massage as well. I also excercise my hands and wrists thoroughly every day. I'm 55 and I want to do this a while longer before the great fishing boat beckons!!
