2. What Is Postnasal Drip?
Most of the time, we barely even notice that nasal mucus is there. It only usually becomes apparent when we are ill and we begin to produce excess amounts of this mucus, causing a runny nose and congestion.
Usually, spent nasal mucus is dealt with by swallowing it, and we don’t usually notice we are doing it. When there is excess mucus being produced, it can accumulate at the back of the throat. This build up can mean that the mucus begins to drip down the back of the throat, causing the sensation that is known as post nasal drip.
