I have had a persistant cough for about 6weeks. It started with just a slight tickle in my chest, with nonproductive cough, but sounded wet when I breath deep. I took Cipro and mucinex for 7 days. 2 weeks after, my cough has gotten worse, feels deep in my chest, I have coughing spells but only cough up clear/white frothy sputum. And I never feel relief, it just feels like it keeps getting worse. Now I have sneezing, sinus congestion , clear mucus, and fatigue from coughing. I'm 39 y/o.
