I have had carpel tunnel syndrome for 18 years, in both hands. Mine was a sudden onset due to childbirth, pulling the handles too hard during pushing. One Dr. prescribed braces to be worn at night. One Dr. asked me if I could still hold a cup of coffee, when I said 'yes', he said come back when you can't.
I've managed to go all these years without surgery, at times yes, it has been quite painful. I have fear of surgeries, maybe unrealistic, but they are there. I suppose it comes from hearing horror stories of people for whom the surgery didn't work, or mangled the nerves. So I did NOT seek out a Dr. who would perform the surgery.
One thing I did do for myself that I have not regretted. A friend practices 'Holistic' medicine and therapeutic massage, she massaged my hands, for what seemed like an eternity the first time. It was much better for several weeks, when I mentioned some pain again, she massaged yet again, this time not quite as long.
She had told me the swelling and lumps were fairly severe in my hands, but that her massage should help. It truly did. I haven't seen her for a few years now, when my hands start swelling again, I try to 'massage' it down. Yes, it is painful, yes my fingers go numb while doing this, but in the end it is worth it. 18 years and I am still surgery free. I can type, knit, crochet and sew with these hands!!
I know this isn't an answer to the question you asked, but sometimes I think some Dr.s rush too soon into surgery, in the end causing more harm than good. Look in your area, see if you can find someone who is practicing Holistic medicine, give it a whirl! I wish you luck!
