I never had sinus problems until I moved to Austin almost 10 years ago (the allergies here are horrible). I had my first sinus surgery about 5 years ago, and my second about six months ago. I have never had polyps, just nasty infections that the antibiotics weren't killing. Oh, and my sinuses is my primary CF problem. I have excellent lung function and no digestive issues. Still, when my ENT looks into my sinuses, he says "you don't have CF!" So, I guess my sinus symptoms are mild compared to some CFers.
