After about six visits I realized I needed the next level of expert, went to large teaching hospital 45 miles away, saw Ear specialist (not ENT, next level). He gave me
Levaquin (horrible drug, nasty!) Seven days later, cleared up, stopped antibiotic, then got what was most likely the flu but I had the flu shot a month before so it blew through me, short but bad. Ear problem came back. Went back on Levaquin a month atter first course and now done with it.
