esther is absolutely right in her comment about "true carpal tunnel" , and that's an example of why you need some competent differential diagnosis. Your mielage will vary depending on your doctor, but what you really want is someone like:

a specialist in MET (muscle energy technique) is probably your best bet for finding someone competent in getting to the true root of the problem, who can work with your doctor, recommend imaging if needed etc. 
People with this training are absolutely among the best remedial biomechanics.

I Know, Tom Ockler helped me tremendously with a severe recurrent neck pain problem. One visit to his clinic was all it took, the follow up visit was just for re-enforcement of what I had learned. Absolutely took care of the problem at the biomechanical root.
I also know cuz I have worked in the field  as a physical therapist myself (tho I left to pursue a start-up 3D graphics thing, thus the Poser) 

tebop, if you can possibly get to NE ohio, go see Tom, he's a good guy. If not, I'm sure he could help you find someone close enough for you to visit a couple times will be all you need.
