Back when I had wrist pain the only thing that worked for me was mousing with a different hand, and using a split Goldtouch keyboard (not a fan of the key feel, but ergonomically it worked well for me). Then I got into weightlifting and I don't have wrist pain anymore and can use whatever keyboard or mouse I want. Not saying this works for everyone, obviously, but give it a try as well. It also works wonders for lower back pain, and just in general makes you feel better.
