What is Sinusitis?

By definition, sinusitis is an inflammation of the tissues that line the sinuses. This swelling prevents normal drainage of mucus through the nose. When the flow is blocked, mucus builds up in the sinuses, resulting in symptoms including sinus pressure and congestion, headache and other discomforts. Chronic sinusitis can significantly impact an individual’s physical, functional and emotional wellbeing.
