I have a chronic cough that used to eventually go away but now it isn t going away. I have gone to a pulmonary specialist who found nothing. I currently am under the care of an allergist who has me on monthly shots and several meds but to no avail. I seem to cough from talking or singing, from eating, from acid reflux. When I get a cold, I immediately get bronchitis. Could I have a nerve in my throats that reacts to eating or talking?
