I forgot that I had this problem in my first pregnancy until I read this post!!! In my case I had it in both hands and it didn't matter what I did it didn't help. In the end I had one hand operated on while I was about half way through pregnancy under local. I can't remember why I had to have the op, but I am guessing it was under extreme circumstances as I wouldn't generally under go an operation while pregnant. My first born was 12 years aso, so things have more than likely changed. Talk to your doctor, or try alternative therapies, its something that was really available back then (alternative) and may have made the difference between managemnt and the operation. It disappeared in the other hand after birth fro me. Hasn't returned in either hand since including next pregnancy and this preg.
