What's Going on Here?

I have had a chronic, non-productive cough for about a year and in the last week developed a very deep cough which is also non-productive; it feels like cement in my chest and I feel tired all the time. My ribs hurt and I have a bit of a headache. Having enjoyed exceptionally good health up to this point, I am not a happy camper. My current doctor, with whom I am not thrilled and am in the process of replacing, has not been helpful. He had some tests done -- chest x-ray, which indicated some scarring from the bronchitis I have had in the past; a stress test, the results of which he did not share with me, and a pulmonary test, which was normal.These tests were done before the deep cough began and I am wondering what could be causing it.

Do you smoke?  I had a cough like you for about 3 months out of the year for the past 5 years - chest x-ray was fine  - but my CT Scan which was done in May for other reasons showed moderate emphysema - have a CT Scan done to rule out emphysema.
