My Neurologist did an EMG and they poke needles (not pleasant) on neck, biceps which showed some abnormality on nerves. Now Neuro referred to a Spine and Pain doctor and was given Cervical Collar to begin with which sure helps a lot to minimize my headache and face pain and dizziness. I am also little addicted to it.

Next is to try Prolotherapy and then Botox etc., So you can get an EMG done by a Neurologist on your neck to begin with I guess.

Not sure what other types of nerve tests are there.

Cheers!
