Chronic Cough Causes

5. Postnasal Drip
When we get a cold, flu, or one of many other illnesses, we are likely to start producing a lot more mucus than we usually would. This excess mucus has to go somewhere, and this usually means down the back of the throat. Nasal mucus is usually disposed of this way and we don’t usually notice it.
When it is present in higher than usual volumes, however, the extra mucus dripping down the back of our throat can become very noticeable indeed. The patient will often be able to feel the mucus and it can also cause some irritation – resulting in a cough.
