You need to do a spirometry test in office and get an oral swab culture done and
clear this up.
Allergy to what? Advair? Flovent? aka Flonase
, I had a doc tell me to spray Flovent up my nose, as if he didn't believe me about use of Flovent. What an idiot, same stuff. I always bleed about a week after use of this. I stopped all the junk, and rinse with warm saline, Neilmed premixed saline packets and someone gave me several bottles of Alkolol rinse, this helps with sinus issues.
