2012 Guyon's decompres. On R wrist.6 yrs pain. Cervical straight neck. Bilateral ulnar pain @wrist & elbow. Shoulder/Trapez. Intense pain. Diagnosis? HELP!

Complicated. That sounds like a very complicated problem that has no simple solution. You have had all the diagnostic tests and used the medications I would have tried. Have you seen a neurologist or a pain specialist? This would be my own recommendation at this point.
