I have had a similar problem which my Asthma/Allergy Doctor has given me like 5 things to take. Spiriva, Asmanex, antibiotic, Certuss, and probiotics. I also, last week had a cortisone shot. I have less mucus and am feeling better. I go back in a month for another checkup. They always do a breathing test. The Dr. said she is treating me for chronic bronchitis. If I had been a smoker or been around smoke my symptoms are like COPD.
