sinusitis
"Had severe sinus infection caused by allergy and polyps.  Treated infection with Zithromax and would get relief as long as treatment lasted. Within days symptoms would start to return. First Zithromax treatment was for 5 days then twice in 14 days. Went to a specialist and he recommended surgery for the polyps and prescribed Levaquin for the infection. Felt relief within days and weeks later no recurrence of the infection.
Will still need the surgery. I've had it twice before. The recovery time from surgery is about 3-4 weeks and very miserable but worth the agony for the relief it brings.
Due to the side effects, etc., be sure it's an infection and not just a virus prior to starting antibiotic treatment."
