I feel and share your pain. I have started to develop
Dupuytren's contracture in my right hand and was told that there wasn't much that could be done, except an operation on the hand when it became too restricting, I then broke my wrist in a bizarre gardening accident! (Usually happens to Spinal Trap drummers) and have lost the feeling in my left hand middle finger so no more Johny Cash poses! I struggle on with it but I do feel that I'll never feel the response from my hands when I'm playing that I felt before the accidents. An upside is whenever I make an absolute arse of any bassline I'm playing I can always play the "doing the best I can with MAJOR hand issues" card.
