I used to have chronic sinus problems until a pharmacist told me about 'nasal saline'. I tried the aerosol form, hated it, I use the squeeze bottle. About $2-3. I haven't had a sinus infection since! Since it the same saline they put in IV's, there is no symptom rebound, drug interaction problems, nor bad side effects. I hope it works as well for you as it did me. Dr. Oz recommends a 'Neti pot' for the problem.
