Read "Healing Back Pain: The Mind Body Connection" by Jon Sarno.[1]
I lived with chronic knee pain for over 8 years, and would routinely have "carpal tunnel like symptoms" with my wrists.
Literally within a week of reading that book my knee pain was gone, and my wrists have not had any issues since. My personality type is exactly that described in the book, so it might not work for everyone. But boy howdy it worked for me.

Edit: As it relates to the article - Dr. Sarno attributes most of the pain to your brain and unconscious emotional rage. It sounds kind of quackish, but he lays out excellent explanations of how your brain works against you to cause this chronic pain. I was a skeptical as well (I won't give away spoilers but the treatment plan is HILARIOUSLY simple) but it has really worked for me.
