My problem is environmental..I live in Florida and have this problem for 4 years and 3 surgeries later. I also have the pseudomonus bugs in sinuses and lungs. I have a great ENT and lung doc working together on this recurrent problem I also have been doing allergy shots which help a lot ..oak pollen is a real problem here.
At one point I was on IV Antibiotics for 8 weeks ...but bottom line it comes back!! I use every steroid nasal spray known to man, some relief but not a cure. Guess we need to live in a plastic bubble ...pray and spray
