However, the orthopedic surgeon did the median nerve surgery. I can recall one patient few years ago came with symptoms of CTS. The problem there is no good correlation between symptoms and NCS abnormalities (if any). But such cases are uncommon or rare, also has to be mild.
If they do then it is likely that it is carpal tunnel.
A good way to find out would be to purchase carpal tunnel wrist splints and wear them mostly at night for a couple of weeks to see if symptoms improve. Yes there are EMG negative Carpal Tunnel Syndrome in which the patient has the clinical signs and symptoms (check out ) of carpal tunnel yet have a negative EMG. Can you have a normal EMG test yet still have carpal tunnel syndrome? I have heard of something called Clinical & have heard about something else that has to do with being undetectable for some reason? Please advise.
