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

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