I broke my wrist and dislocated 3 of the bones that lead to my fingers. The doctor did a carpel tunnel release while he was in there fixing the bones even though I didn't have any numbness before the accident. I had numbness afterward from nerve damage from the injury, but it went away after several months. I think nerves tend to heal themselves over time. I ain't going to say anything about that EMG test but report back afterward and then I'll tell you about my experience. Everyone I know who has had carpel tunnel release turned out fine and it was fixed.
