I had to take a minute to reply to this, so please understand this is just my opinion and you definitely need to make your own decisions concerning your health.
I don't know if you are considering this procedure because it effects your ability to play or that you just have a lot of pain from doing computers too long. I, myself have a bad disk and pinched nerve from decades of computer use, my right index finger has been numb for over 2 years. (I have to use Dragon speech software to do emails or long replies to this forum) I'm on temp disability (workers comp), cannot work in my present career anymore, can't play long sets at night clubs/bars, and am looking at probably going on permanent disability in the end, I was presented with the option of getting a surgery but it was too risky to me cause it's in my neck and if something goes wrong.........it can be very very bad. The 3 main complications could be increased pain/numbness, multiple surgeries, or paralysis, and the complication rate is 10-15%...........I didn't like the odds and just deal with the pain. (Acupuncture helps!!!)
I know in that surgery they cut a tendon to take the pressure off the nerve, we both know that will effect how your hands are gonna work, so do as much research as you can before you go under the knife. The less invasive stuff you have done, the better off you're gonna be in my opinion.
When they presented the option to me I simply said to myself...."Get a surgery to be able to use computers again? (*even though the doctor said that even if I get it done I should get away from typing & computers)...........I said NOPE. Now if it was a case of never being able to play guitar again?...I would have thought long and hard about it and probably gave up the six string, maybe even music altogether. I knew a fabulous guitar player in my part of SF, of all the cats in Northbeach (and this is a musicians haven) he was one of the few that could stretch me, when we jammed together we took over the sessions. We really locked in when we played for some reason. A few years ago he had some kind of wrist & arm problem that ended his playing days, he gracefully moved on and picked up the harmonica as a hobby. It did give me some perspective as to what is important, living life even if you have to make tough decisions.
Again, I don't know if this is so you can play guitar or because of work related issues but I hope it gives you some perspective. Good Luck with this!!!
