Post nasal drip: The nose normally produces mucus, which traps substances like dust, pollen, pollution, and germs such as bacteria and viruses. Mucus flows from the front of the nose and drains down the back of the throat. When mucus production is excessive, it can flow from the front, as a runny nose, or become noticeable from the back, as post-nasal drip.
