Just thinking...someone mentioned the possibility of neck issues that might be casing hand problems. I'm not sure that a hand specialist will necessarily take that possibility very seriously given their focus on hands. Doctors can be surprisingly un-systems oriented. If it is a neck issue, hand surgery won't likely help.

Take care and get the whole picture before you go the hand surgery route. I might be inclined to try less invasive options forest, including acupuncture and chiropractic. But that's just me and you know your situation best.
