For the past three months, I have had chest and sinus congestion, manifesting itself in hacking/coughing, wheezing, and expectorating thick yellow (various shades) mucus. I "sound" like I have a cold, but I don't. No other symptons have been present. Two regimens of antibiotics have proven to be ineffective. I am using daily the generic equivalent of Flonase, am also taking an antihistamine, Advair, and doing nasal irrigation with a neti pot.
