Sore throat caused by postnasal drip

Postnasal drip is when mucus from the nasal passages and sinuses drains into the throat. Postnasal drip can cause a sore throat, laryngitis, a cough, bad breath, hoarseness, and sometimes wheezing.

Postnasal drip often improves on its own, but if it lingers it may need treatment with medicines.
