I was diagnosed with Arthritis in my hands in feet a while back. It used to be that my feet and ankles where the problem and in fact what I first sought medical advice for. But now my fingers, hands and forearms have been getting progressively worse. We just finished building a green house and it just about killed my fingers. They ached so much every night during the build. I ended up buying a nail gun so I didn't have to grip a hammer or drill. Also, now I find that I can barely play a 6 string acoustic guitar. I cannot form a simple D chord at all and can just barely play a C chord (barre chords went long ago) . This makes me sick to think about. I cannot snap my fingers or touch my little finger and thumb together...try it...I can't do it, not even close. Bass wise, I can still play albeit not like the old days but I accept that at 66 years old. I can and do still play bass gigs once or twice a week. My fingers may ache after the second night but I can play. But what's next? Who else suffers like this and what can be done?
