I'm 55 and I played electric for 30+ years. I got an upright this spring and I've hardly touched the electric since. I practice 1 to 3 hours most days of the week. And recently more since I've had some gigs. Now I have pain and some redness and swelling in the last joint (closest to the nail) on my 4th finger of my left hand and a lesser amount of pain on the same joint on my 1st finger. What do other bass players recommend? Rest it completely until it goes away? Tough it out? Adjust my technique? (I don't always support my 4th finger with my third as I've read you should do). Any advice would be greatly appreciated. I am so excited about learning this instrument but I want to avoid a long term problem.
