Sinus Infection and Cough: Understanding the Connection

Yes, cough is a common symptom of sinus infections. Inflamed, congested sinuses produce excess mucus that drains down the throat (postnasal drip), triggering coughing. This “postnasal drip cough” or “sinus cough” may be productive (bringing up mucus) or dry. Coughing can worsen sinus congestion and pain.
