What is a sinus infection?

Stuffy nose that just isn’t getting better? You might have a sinus infection, also called sinusitis.
A sinus infection can occur when your nasal cavities become infected, swollen, and inflamed after fluid becomes trapped in the sinuses, allowing germs to grow. A previous cold or agitated allergies may be followed by sinusitis, even after other upper respiratory symptoms are gone.
