Given you said you had a bad infection ("terrible flu", though antibiotics won't help with true influenza, which is viral), the possibility of a post-infectious molecular mimicry autoimmune attack on the nerves should be considered. Certainly, Guillain Barre is suspected to arise from this mechanism, as are certain other acute-onset neuropathies:

The above page comes from the Washington University at St. Louis Neuromuscular web site, which is an excellent database of neurological conditions.


And, just in my experience, most neurologists who do not specialize in neuropathy might have little idea how to test for such conditions. Going to Mayo is a suggestion, but in my opinion, Johns Hopkins in Baltimore, Cornell-Weill/Columbia in New York, or The Jack Miller Center in Chicago might be better bets, if travel and money is not a concern. All of these centers are major research facilities for neuropathies, have done much of the work in identifying their complexities, and may be better at getting to a diagnosis.
