SBL
I too suffered from CTS when I was a climbing guide and instructor in Colorado Springs - I used power putty and stretching to provide relief. And it worked. If you know a massage therapist (shot in the dark), contact them for help The sooner the better as CTS can require surgery if gone unchecked. Don't so that to yourself. You are one of the better people on this board, and if you get surgery, your posts will take twice as long to type!
Here is some info on wrist exerciser-type devices:
