That is precisely what I HAVE! I have had two sugeries by a top Otolaryngologist who said it was very oderous at the time of surgery as I had dark green chuncks falling down my throat. He says fungus is the HARDEST to treat of all sinus conditions & is like backache..one has to sort of live w/it! I use a corticosteroid nose drops, take Nystatin which is FOR fungus anywhere in the body & I have it elsewhere also. I have read from my Harvard & John Hopkins & Mayos letters that ALL sinus is fungus and NOT bacteria..written by the specialists in that field. They were debunking the doctors who treated sinus infections with antibiotics, which I had many xxs with NO results. Nystatin is FOR fungus, is a liquid, 3 teas a day & I'd recommend it as it not bad tasting.
