You’ve got pain and pressure in your face

Sinuses (which are cavities behind the forehead, nasal bones, cheeks, and eyes) do have a purpose. One is to help warm, filter, and moisten the air that you breathe in.

Another is to make sure your head isn’t too heavy. Sinuses “open up space so that your head doesn’t weigh a ton,” explains Louis Papa, MD, an internist and professor of clinical medicine at the University of Rochester Medical Center in New York.

But if the tiny holes that connect the sinuses to your nasal passages become plugged, they can’t drain properly. The accumulation of mucus results in a feeling of heaviness in your face as well as pain from increased pressure on your nerves.
