I had a similar experience: keeping my hands warm while keyboarding made all the difference.
Before this I was at 20% use for 3 years, tried multiple things, went to multiple doctors, etc.
I also: wear a pil-o-splint while sleeping so that area of my wrist can relax at night, make sure my hands are warm and that I've stretched before starting for the day, and changed my typing posture so that my hands are mostly flat and wrists don't touch the desk/keyboard while typing.
Finally, I stopped using emacs and the like because of the control key induced hand/finger stretching. Vim is more RSI friendly in my experience because there is less stretching required to use it.
