Nasal discharge - Overview

Alternative Names

Runny nose; Postnasal drip; Rhinorrhea

Definition of Nasal discharge:

Nasal discharge is any mucous-like material that comes out of the nose.

Considerations:

Nasal discharge is common, but rarely serious. Drainage from swollen or infected sinuses may be thick or discolored.

Excess mucous may run down the back of your throat (postnasal drip) or cause a cough that is usually worse at night. A sore throat may also result from too much mucous drainage.

The mucous drainage may plug up the eustachian tube between the nose and the ear, causing an ear infection and pain. The mucous drip may also plug the sinus passages, causing sinus infection and pain.

Common Causes:

Bacterial infections
Colds
Flu
Hay fever
Head injury
Nasal sprays
Sinusitis
Small objects in the nostril (especially in children)
