That's very interesting to hear your connection btwn small fiber & trigeminal neuralgia. I have had peripheral neuropathy (Related to antibodies) for a year and in the past 3-4 months have been experiencing lancinating pains on my right face and was curious if it was trigeminal but haven't addressed it with my doctor yet out of fear he would think I'm crazy-- since your trigeminal is a a cranial nerve, whereas your small fiber neuropathy is a disorder of the peripheral nervous system.

I would only think that the two are related if you have a disorder affecting your central nervous system (brain and spinal cord).

If you have risk factors for trigeminal neuralgia (history of blood vessel disorders, multiple sclerosis, age 40-60) that would likely make you consider that it may have been a separate, isolated incident.

It would be interesting to hear back if you find out the link.
