I was diagnosed with small fiber neuropathy via skin biopsy. I'm trying to understand my health issues and I'm wondering if it's possible to have a painless form of SFN that presents with fatigue, poor sleep, exertion intolerance, mild intolerance of upright position.
I later developed more...

I found this interesting because it claims that in small fiber neuropathy, most patients had intense fatigue, myalgia, and subjective weakness and lower intensity of neuropathic pain.

A clinical geneticist believes that a rare variant in the SCN9A gene could be responsible for at least a part of my symptoms. The variant is extremely rare (1 in 1.4 million alleles) and not found in healthy people.
The gene is associated with small fibre neuropathy which would fit, but there...

I recieved this newsletter and could not find it posted on the Internet, so I thought I’d post the text. This is a newsletter from a small company, Winsantor, who is testing a topical drug (WST-057) to see if it increases small fiber nerve density (and improve symptoms?) in diabetic patients...

Abstract
Background
The role of cytokines in the pathophysiology, diagnosis, and prognosis of small fiber neuropathy (SFN) is incompletely understood. We studied expression profiles of selected pro- and anti-inflammatory cytokines in RNA from white blood cells (WBC) of patients with a medical...

Abstract
Background and Objectives Various peripheral neuropathies, particularly those with sensory and autonomic dysfunction may occur during or shortly after acute COVID-19 illnesses. These appear most likely to reflect immune dysregulation. If similar manifestations can occur with the...
