“Pains, chills, fatigue, vomiting and vertigo plague me. Small fiber neuropathy causes it all.”
Small fiber neuropathy is one of many kinds of peripheral neuropathy. Many cases of small fiber neuropathy cases are caused by diabetes. Other causes include some autoimmune disorders, some cancers and chemotherapies, HIV and certain HIV drugs, alcohol abuse, vitamin B6 toxicity, celiac disease and several rare genetic disorders.
But in at least 40 percent of cases, no cause has yet been found, so doctors use the placeholder diagnosis of “idiopathic small fiber neuropathy.” “Idiopathic” means of “unknown origin.”
