Post-nasal drip occurs when thick or excessive amounts of mucus drip into the back of the throat. The inflammatory substances in the drip coupled with trying to clear the excessive mucus, causes irritation and discomfort. Excess mucus running down the throat may cause hoarseness and lead to a cough. In fact, post-nasal drip is the most common cause of coughs. Other common symptoms include tickling in the throat, snorting, constant clearing of the throat, and difficulty breathing. A sore throat results due to the continual attempts to clear the excess mucus.
