Hi Billyline.
I am sorry you have these symptoms.
I think the first thing you should do is to find a good neuromuscular neurologist that is a specialist in neuropathy. Any doctor that says" it is nothing serious, just SFN" is not worth your business.
SFN can be caused by a variety of , yes, serious, complicated and often cronic conditions/diseases.
So you should find a doctor that takes your interest and find the underlying condition.

You should ask the neurologist to have a skin punchbiopsy done. This is the standard to diagnose SFN

And, yes, SFN can be very difficult, painful, debilitating to live with.

Also one more question, you mentioned eyelid. Do you have dry eyes, dry mouth? Do you have joint pain?
These symptoms in addition to your SFN can be some autoimmune disorders that your neurologist caninvestigate and perhaps refer you to a rheumatologist.


Debi,
you mentioned your SFN symptoms in teeth. Do you get numbness in your gums? I do. Sometimes it feels like there is pain deep inside. My upper gums feel like frozen with numbness. It makes me worry that there is not enough blood supply, or perhaps just the numbness from small fiber damage.?? what is your opinion? ( if you have this symptom)
All the best
