I never thought I could have Lyme either. Never saw a tick bite(leading research indicates mosquito's can carry lyme too) or even a tick for that matter! I later found out through a specialized lab, that i DID in fact have lyme and several other infections carried by ticks. Lyme disease causes small fiber neuropathy and several other neurological conditions. I went undiagnosed(and therefore untreated) for several years which is what my neuro's say likley caused the SFN. I recently met a gentleman who had been suffering from neuropathy for 10 years. He went to a specialist in NYC who diagnosed him with Lyme. He was put on IV antibiotics for 9 months and is now off all pain meds(was on 5 different pills and pain patches). He had no CLUE he had Lyme. I don't mean to push this potential theory, it's just something that should be considered if looking for the underlying cause(specifically because of your early rash, a text book sign of Lyme). Food for thought...
