What should you know about sinusitis?

ANSWER

The sinuses are small cavities in the skull that are normally filled with air. They make mucus, which helps keep the nasal passages clear of allergens and pollutants. Sinusitis is an inflammation of the tissue that lines these cavities. In some cases, this swelling blocks off the sinuses, trapping mucus and air inside them. This can cause pain and pressure. Sometimes, it can lead to a bacterial infection.
