I have mild asthma. Have had a irritated barky cough since July. Got started on atrovent, dulera, singular, , and atrovent for emergencies. After two rounds of abx for sinus infection which exacerbated my symptoms I am still coughing!!! I have a small amount of secretions when I cough which taste yucky and metallic. My bronchi are so irritated I am short of breath and the only thing which slows down my cough is Thessalonians perles and cough drops. What else should I do?
