sore throat caused by post-nasal drip

inside view of mucus draining from nasal cavity into throat, causing sore throat.

post-nasal drip is when mucus from the nasal cavity 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.
