What is Sinusitis?

Sinusitis is a common medical condition that affects the air-filled cavities around the nose, including the forehead, cheeks, and upper jaw. Inflammation of the sinus lining causes blockage of mucus drainage, leading to nasal congestion, difficulty breathing, and pain or swelling around the eyes.
