32 yr female w5 yr ulnar wrist pain.no motor loss.burns/aches/numb.painful to type, apply makeup, write.xray, ncv, emg negative.pain on pisotriquetral joint.ulnar/median decompression.no mri.what's wrong?

Mri: Sounds like the MRI will probably be very helpful in this case.

Wrist pain: Without an mri- it sounds like wrist tendonitis with or without compression neuritis. I would consult an orhtopedic surgeon. Sometimes an injection of xylocaine (lidocaine) with a steroid will alleviate the pain. Also i always suggest the use of a pull on, neoprene tubular wrist support worn over a terry tennis wrist towel: it will really help.
