Dr. Corey Clay answered

Specializes in Allergy and Immunology

Maybe: Persistent post nasal drip (allergy or non-allergy related), acid reflux, asthma, or vocal cord problem are common causes for persistent cough. Medication side effect is often overlooked as well. Consider a virtual consult to discuss any related symptoms and more about your history for guidance.
