I've had same problem numbness in my left pinky and ring finger a few years ago now getting same for the right side ..: I just go on .. doctor suggested surgery as well but said its not 100% cure , it might come back later also ... it's a factor of getting older ... the pain is not pain ... just numbness , irritating but better than being cut open and the cortisone injections didn't work well and needing to repair and repeat a few years down the road again ... I use a handheld thumping massage machine to relax the muscles... sort of helps ... no surgeries for me .. just my take ... I just don't want to be put under/knocked out ... lots of things can go wrong when you're put under ..
