Sinusitis: What Is It?

Sinusitis, a sinus infection, occurs when the sinuses become infected or inflamed. The sinuses are air-filled spaces located within the bones of the face and skull, and their primary function is to produce mucus that moisturizes the inside of the nose, preventing it from drying out. When the sinuses become blocked due to factors such as allergies, infections, or structural issues, it can lead to the development of sinusitis. Sinusitis is the inflammation of the sinus lining, which disease, allergies, or structural abnormalities can cause. It can be acute (short-term) or chronic (long-term), depending on the duration of symptoms. Sinusitis What Is It
