Cubital
tunnel is mostly experienced by men but whereas
carpal tunnel is impingment of the ulnar nerve in my elbow. I've had surgery on both, twice.
The EMG would have shown if you have nerve damage so that is good news that you don't. The tests on my left arm and hand were worse than my right, however, the right hand, arm and elbow are where I have the majority of pain so that is the hand I chose to focus on, I am also left handed and didn't want the down time.
