I'm going to neurogist to have nerve test done on my neck.what are doctors looking for. i have severe pain in my neck, and head.

Pinched Nerve: I believe the neurologist is going to perform an emg/ncs, an electrical test of your nerves and muscles to determine if you have a nerve that is being compressed, that is the source of the pain. The test consists of 2 parts, the conduction component, where thy run a mild shock up your arm and record how fast the shock traveled. The muscle part is uncomfortable, small needle in your muscle.
