I encountered wrist pain as well, however I was lucky enough to not experience the numbness.
And, I found a solution that works for me!
Its an exercise for CTS. Basically, one is to do the following 10 times before and after using a computer for an extended amount of time.
- Outstretch your arms, hands extended, hands flat, arms flat, fingers pointing straight, kind of like a zombie when he is walking.
- Start bending your hands toward you, so that, in the end, you look like you're pushing against a wall. Make this movement slowly, and hold it for about 5 seconds.
- Slowly flatten your hands out again, and let them sit for another 5 seconds.
- Then, slowly tuck in your fingers downward into your palm, slowly making a fist, and bending it downward to point towards the ground. Hold this for about 5 seconds.
- Again, list up slowly, straightening hands again.
- Repeat steps 2 -- 5, 10 times.
- After, let your arms hang, and shake your wrists.
Oh, and http://www.eatonhand.com/hw/ctexercise.htm I got the above information from. It will probably be more helpful as there are pictures, but I guess I'll leave what I wrote, anyway.
I personally don't do it everytime I use the computer, especially before and after. Its more like, when it starts hurting again, I'll do it. Of course, that isn't good. But, I mean to say that it seems to help me.
