Postnasal Drip

Postnasal drip occurs when mucus from the nasal passages and sinuses drains into the throat. If the mucus becomes thick, postnasal drip can cause problems such as a sore throat, laryngitis, a cough, bad breath, hoarseness, and sometimes wheezing.

A problem caused by postnasal drip often improves on its own, but if it lingers, it may need treatment with medicines.
