I stopped playing double bass seriously when I was younger partly because I developed increasingly worse pain in the little joint of my left hand pinky. I'm starting to play again, but the pain has already returned. Orchestral work is probably out of the question, but I'd like to be able to play jazz for longer than a few minutes without it hurting. Are there any known issues that affect that finger joint? And are there any ways to make it hurt less? Do they make mini braces like you wear for bad knees that work on a finger? Or certain treatments that'll help? I've talked with my doctor in the past, but he wasn't much help. I have adjusted my playing style to reduce use of the finger, but that only delays onset of the pain...it still becomes unbearable after a couple hours of playing.
