Hi, I had a dry cough which lasted for 3 weeks before christmas (it cleared up when I decided to make a dr appointment). Anyway, the cough is back (for over a week now) it has been accompanied by loose stools, intermittent pain on left side of my chest. I am asthmatic and have been needing to use my reliever more frequently. I have also been vomiting - this is at least daily but not frequent, possibly a few times a day. I am getting tired and would appreciate any insight into what is causing these symptoms. I am female, 39 and smoke 15-20 cigs a day. thanks
