I am allergic to nine enviromental allergens and have been taking
fluticasone propionate (flo-nase) for the past three monts and it's been working fine to treat sinus pressure, my only main symptom. However, since i started, i've noticed for the first time in as long as i remember that i've been getting thick nasal mucus either dark red or black, sometimes streaked and sometimes completely colored, while before it's always been thin and clear.
