I've dealt with it. I broke my arm 3 years ago riding horse, and after it was healed, my hand was numb most of the time, and very cold. I had an EMG and a nerve test, and my nerves were actually dieing, FAST. So, I went in the very next day for carpal tunnel surgery. The surgery did NOT make my hand not numb anymore, or stop it from being cold, it just made is so the nerves weren't dieing. I had another problem though, my bones or something was pinching my nerves. I endured 5 more EMG's (electromyogram) and nerve tests. Finally I had another surgery where they put tubes around my nerves, and that has solved the numbness problem, but I still have great pain when I need to write/ take notes/ etc.

The EMG's are not fun, usually when you have the little prickly needle thing, you also get the one where they shove needles into your muscle, move it around, and then shove it in deeper, THEN moving it 3 inches and doing it over again .. . all the way up to your arm pit. .

I would have the surgery again though, because it stopped the death of my nerves, it was an outpatient surgery, and, the recovery time is very fast. I was in a wrap for about a week, and was able to do mostly everything on my own.

Good luck, let us know how it goes!
