I have it, and am currently trying to use Flonase daily to see if that helps. It seems for me, if I get any type of congestion, cold, allergies, anything, it turns into a full blown sinus infection. My primary care dr, recommended we try this before going to an ENT, and I agreed. I'm definately not for doing sinus surgery unless ABSOLUTELY necessary!!! So far, the Flonase has helped and I haven't had a sinus infection in almost 2 months!! A near record for me, especially during allergy season. We'll see how this works, and if it fails, then it's off to the ENT.
