You shouldn't use wrist wraps while you're typing. They're strictly for use when you're sleeping or otherwise relaxing. There's a lot of misinformation and bogus products out there about RSI... my advice to you is to read a book by a good doctor, like Dr. Pascarelli's Complete Guide to RSI (http://www.amazon.com/Pascarellis-Complete-Repetitive-Strain...)
STOP right now! I can't stress this enough. I had to stay away from computers for 2 years because a a sudden pain that appeared on one night of development and which i tried to ignore.
