Nasal congestion, also called stuffy nose, is a feeling of fullness in the nose or face. There also might be fluid running or dripping out of the nose or down the back of the throat.

Nasal congestion is often called rhinorrhea or rhinitis. But the terms are different. Rhinorrhea involves a thin, mostly clear fluid running from the nose. Rhinitis involves irritation and swelling inside the nose.

Rhinitis is the usual cause of nasal congestion.
