The sinuses are air-filled cavities that surround the area above, below, in between, and behind our eyes. They create mucus, which keeps the inside of your nose moist and helps protect your body from pollutants. Sinus infections occur when the lining of the sinus cavities becomes inflamed, leading to a build of mucous. This creates the perfect breeding ground for bacteria and other microorganisms.
