Nasal discharge
Definition
Nasal discharge is any mucus-like material that comes out of the nose.
Alternative Names
Runny nose; Postnasal drip; RhinorrheaConsiderations
Nasal discharge is common, but rarely serious. Drainage from swollen or infected sinuses may be thick or discolored.
Excess mucus 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 mucus drainage.
The mucus drainage may plug up the eustachian tube between the nose and the ear, causing an ear infection and pain. The mucus drip may also plug the sinus passages, causing sinus infection and pain.
