I have dealt with carpal tunnel pain here and there over the years. Pregnancy and holding babies would affect it but it was never really bad.
In recent years I have used a laptop computer instead of a desktop and the carpal tunnel was becoming more noticeable. If I used the computer much during the day I would have pain in the evening or the next day.
I realized that with the laptop, I type and my wrists are resting right on the hard computer. (With a desktop I am positioned better and my wrists aren't touching anything.)
I looked for something to put on the computer to cushion my wrists but didn't find anything that looked like it would work. I ended up buying wrist braces that I use if I am going to use my laptop. This has completely solved my problem. If I am good about using the wrist supports (which cushion my wrists as well as stabilizing them) I do not have any trouble with carpal tunnel. If I get lazy about it I start to notice some nerve pain.
I do not have to wear the braces all day or when I am sleeping, or even when I am using a desktop computer. Just when I am using my laptop.

At the drug store you can buy an arm brace for carpal tunnel. It doesn't look like it would do anything, but if worn for a few weeks it does. Cured my wife... And it was so simple.
