Definition of Nasal discharge:

Nasal discharge is any mucus-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 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.

Common Causes:

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