Wow.I had carpal tunnel release on both hands, as well as a cubital tunnel release and transposition (elbow nerve). It took about 2 months after the second hand was completed before I could return to work (computer job). I still wasn't very fast on a keyboard, but at least I was getting paid.
It took much, much longer before I could play a bass. About 5 months after the surgery, it was still quite painful to try to play after even a minute or two. By 3 years after the surgery I still couldn't play for more than a few minutes without burning pain and numbness. I sold my longscale basses, keeping only an ultra-shortscale Mikro, quit my job, and became a full-time Dad.
Within a few months of not sitting at a keyboard all day, I could play again! I still play shortscales, only with a pick, and I try to pay very careful attention to my wrist angles on both hands. As long as I do that, I can play 30-45minutes without too much trouble. I will need to build more stamina if I want to gig again, but I can finally play for fun.
My experience was that the total load on my hands had to decrease after the carpal tunnel surgery. You might have the same experience; that you can work a desk job, play video games, or play bass - but not all three, all the time and every day. The reduction in hand use, rather than recovery time, was what limited music for me. I'd also recommend revisiting the ergonomics of your playing when you start up again. Make sure your left wrist is as neutral as possible, with no extra tension anywhere from fingers to neck. If you play finger style, make sure your right wrist doesn't have a sharp downward bend when you pluck; adjust the base and your elbow so the wrist is closer to straight to increase the volume of the carpal tunnel and reduce the chance for nerve problems. Good luck!
I really believe playing bass would be great PT.
Now I just have to convince my head. Surgery can play mental games with a person.
Thank you for sharing your experience.
