What is sinusitis?

Sinusitis is an infection of the sinuses, the small air-filled spaces in the bones behind the forehead, around the nose and eyes, and under the cheeks. The sinus cavities are lined with membranes that produce mucus.

When the sinuses become infected by a virus or bacteria, the sinus membranes become inflamed and make more mucus than usual, resulting in a blocked or runny nose and blocked sinuses.
