Hi, my question is for an ENT If possible.......I have some minor allergies.....but after many years as a flight attendant in the air with cigarette smoke and pesticide sprays.......or for whatever other reasons.......I developed polyps and had sinus surgery two years ago. I am leery of the polyps returning and have been counseled to start taking Singulair as a preventative. Curious about the latest opinions about that strategy. Thanks. Karen
