Introduction

The air-filled structures underneath the face are called sinuses. Sinuses produce mucus, which works like a drainage system that keeps the nose clean by eliminating the bacterias and allergens. Sinusitis is a condition that causes inflammation of the tissues lining the sinuses. When viral and bacterial infections or allergies irritate them, they get blocked or filled with fluid, causing severe pain and pressure in the nasal congestion and face. A wide variety of factors contribute to this condition including common cold and allergies.

One important thing to remember is that the condition is not contagious itself but the viruses or bacteria causing this condition may transmit from one person to another.
