Question for the OP.. your EMG was negative?
How are you sure that you have PN?
Or are you going based on sx's and assuming that you have small fiber (which generally wouldn't show on an EMG?)




As for my own testing:
I've had the slew of blood tests:
Diabetes, B12, other metabolic crap (just cause I eat like crap), I am pretty sure they tested me for HIV as I had to sign a concent form for one of the blood tests.

They did an ANA, and anti-MAG, and all the other funky ones when I went to MAYO.

I've had my thyroid tested, kidneys, etc.

EMG shows a length dependent demyelinating (sensory greater than motor) polyneuropathy, with a secondary axonal loss. **Had 3 EMG's, which all point to the same thing**

spinal tap was normal.

Just had a nerve biopsy on 11/24/09.. waiting for the pathology, have a follow up in neuro on the 8th.


Pain management- not needed.

Thankfully even though I'm mostly sensory, I have numbness and very little issue with pain.
Although, I have been having increasing problems with hypersensitivity.
