chronic dry cough, tickle, bronchitis, shortness of breath

Please advise about chronic cough that is not productive...tickle dry cough, bronchitis, shortness of breath with and exertion or change in position, or action like answering the phone. I am a non smoker. This cough is worse in the morning and at night.
I am looking for a list of things to try, as I am running out of ideas. I have worked on this for years and it seems to be taking over my life. I am 57 years old. Tweet
