Can Nasal Drip Cause Dry Cough?

Postnasal drip is when mucus from the nose and sinuses drips down the back of the throat. When the mucus drips into the throat, it can trigger a cough. Although this cough is often productive, it can sometimes also be dry. Postnasal drip often occurs with a sinus infection or due to a nasal allergy, such as hay fever.

How do I know if my cough is post-nasal drip?

If you have a cough that won't go away, along with nasal congestion, dripping mucus in your throat, a hoarse voice or morning “gunk” in the back of your throat, you may have UACS from postnasal drip.

Does drainage cause dry cough?

The short answer is yes, sinus drainage can cause a persistent cough, although there are other triggers for a cough as well. It is natural and normal for the glands in your throat, airways, nose, intestinal tract, and stomach to produce mucus.
