Rhinitis
"Awesome! For years I suffered sinus headaches, which are much like Migraines. Flonase has alleviated that tremendously. I don&#039;t take this all the time just when I sense allergy season, or plan to be somewhere, where there is a atmospheric change like the mountains or in an airplane. It keeps my sinuses from swelling, causing the headache, it&#039;s not an instant fix, it takes about 11 hours to be effective on me."
