Sinusitis is an inflammation, or swelling of the tissue lining your sinuses (spaces in your forehead, cheeks and nose usually filled with air). It causes facial pain, a stuffy or runny nose, and sometimes a fever and other symptoms. It’s usually caused by the common cold, but other viruses, bacteria, fungi and allergies can also cause sinusitis.

Sinusitis itself isn’t contagious. But the viruses and bacteria that can cause it are. 

Inflammation can occur because of conditions such as structural issues in the nose or a sinus infection. The terms “sinusitis” and “sinus infection” are sometimes used interchangeably.

Your sinuses are four paired cavities (spaces) in your head. Narrow passages connect them. Sinuses make mucus that drains out of the passages in your nose. This drainage helps keep your nose clean and free of bacteria, allergens and other germs (pathogens).
