Hi Mary,
Hello and Welcome,
I noticed this part in your post-
[I have carpal tunnel, tennis elbow, shoulder pain (or maybe its all fibro)...]

An EMG/NCV test should be able prove if it is carpal tunnel or cubital tunnel {tennis elbow} by showing it the nerve is entrapped.

But those symptoms mentioned above could possibly be from Thoracic Outlet Syndrome also.
