Nasal discharge

The emission of fluid from the nose. Nasal discharge is commonly caused by inflammation of the mucous membrane lining the nose and is often accompanied by nasal congestion. A discharge of mucus may indicate allergic rhinitis, a cold, or an infection that has spread from the sinuses (see sinusitis). A persistent runny discharge may be an early indication of a tumour (see nasopharynx, cancer of). Bleeding from the nose (see nosebleed) is usually caused by injury or a foreign body in the nose. A discharge of cerebrospinal fluid from the nose may follow a fracture at the base of the skull.
