What is Chronic Sinusitis?

Your sinuses are air-filled pockets in the bones around your nose. Each one has a small opening that lets mucus drain out. That drainage is what keeps your sinuses healthy.

When something blocks that drainage, mucus builds up. That can lead to swelling and infection. Sinusitis means the lining of your nose, sinuses and throat is swollen. A cold or allergies can start it. When the swelling lasts three months or longer, it is called chronic sinusitis. Not sure if that is what you have? Take our sinusitis quiz.
