Carpal tunnel has a specific set of symptoms that if you don't have them, it's not like you still have carpal tunnel. Many people assume anything in the wrist is carpal tunnel, but it usually (in my experience) isn't. And carpal tunnel is ONLY in the wrist and hand (thumb and first two fingers only), if it's farther up your arm then the problem isn't in the carpal tunnel, it's farther up your arm too. It could be pronator teres syndrome, "double crush," a brachial plexus issue, thoracic outlet syndrome, etc etc....

Also, you'll get a different diagnosis to whomever you go to depending on their specialty, or even if they dont actually have a specialty, they usually have their own fascinations which they will assume. They also will suggest treatments they are familiar with..you gotta shop around a lot and do your own research (with a grain of salt from the internet...it can be tricky) and its often trial and error.

Don't give up.
