I have had a persistent cough for over 6 weeks...I’m never sick, went to my internist and she prescribed an inhaler a couple of weeks ago. I’m starting to wonder if i have something else, allergies? I have had esophageal issues in the past, and had my esophagus stretched but do not have acid reflux, no heartburn. My throat seems raw, but phlegm isn’t really coming up, although I hear a rattle in my chest.
