I've had this problem for 7 months. It started with a sinus infection on New Years Day. I've been on 5 antibiotics, prednisone 4 times, acid reflux meds, allegra, singular, breathing treatments, netty pot, saltwater gargling, all sorts of natural remedies also. I stay away from dairy products also. I started getting better after 5 months but then started all over again. I cough day and night. Nothing seems to help. I've been told I have allergies to dust and mold. Had a scope done with a camera from ENT Doctor who said there's nothing wrong. I've been to Ears Nose Throat Doctor, Allergist, Primary, Emergency, and Nutritionist. Is there anything left to try? I'll do it. This is horrible!View Thread
