One more thing on eyelid tightness....thyroid normal? Exophthalmos? I assume they did thyroid?

If all looks normal, any chance of IVIG?

Interstingly, my PN came on after herniated disc diagnosis, and spinal nerve root blocks. Complicate that with a sky high ANA....who knows? It is really hard to pinpoint etiology. The more one learns, the more one knows there are really few answers. Nerves outsmart us all. I have also surmised that autoimmune conditions hit people who have had major physical or emotional trauma within a few years of diagnosis. Hmmm. Gives credence to psychoneuroimmunology.
