Since nothing else was ever found from other testing, except an equivocal result on Cornell-Weill's own ganglioside agglutinin test, (which is a gross measure of autoantibody activity), my official diagnosis is idiopathic, though molecular mimicry autoimmune mechansims are suspected.

I was tested for a full gamut of known antibodies, but had no detectable levels of any--the ganglioside agglutinin test result implies that something was going on, though, quite possibly involving antibodies unique to me and my small fiber nerves.
