Hi Rio ~ It ALMOST sounds like carpal tunnel to me. Does your thumb hurt alot ~ especially at the base of it?? This can go all the way up your arm to the elbow up to the shoulder. It's very painful !

I believe you - I was told many times there was nothing wrong with my back, until I finally got a doctor to run an MRI on me - THEN they found out I was right! 3 surgeries later, and i'm disabled.

Doctors don't always know what they're talking about. I know you've been to several. Sometimes you have to go to just one more before you find one that will believe you. It's maddening.

Best of luck - you might try a neurologist - if it's the ulnar nerve, it would be under neurology. God bless. Hugs, Lee
