Hi Nonsem:
I went to two neurologists at respected centers who each had me do nerve conduction studies (NCS) and electromyography (EMG). These are usually the first tests a neuro will run to see if abnormalities are detected--as well as blood tests to check for conditions that can cause PN. Your neurologist will probably do these tests, to begin to figure out your diagnosis.

In my case, my NCS and EMGs are normal--so the first two neurologists didn't know what to do, called it idiopathic, and sent me on my way.
Now I am a patient at a specialty neurological institute and have gone through many more tests (spinal MRI, lumbar puncture, and SSEPs), and now I have a diagnosis.

So, the bottom line is that it is great you are being referred to a specialist at Emory. Hopefully, if they don't find abnormalities in the first set of tests,s/he will keep testing till they can get a diagnosis and figure out a treatment that works for you. Take care!
