Your nose and throat make mucus all the time. This mucus keeps your nose and throat moist, and it clears away bacteria and other things that can cause infections and allergies. Most of the time, this mucus is swallowed and you don't even notice it. But when you have a cold, congestion, or allergies, the amount of mucus can increase, build up, and thicken.
The feeling of this mucus draining down the back of your throat is postnasal drip. It often causes a sore throat, coughing, and problems swallowing.
See a picture of postnasal drip.
The increase in mucus that leads to postnasal drip can be caused by a cold, flu, allergies, sinus infections, or hormonal changes.
Clean the inside of the nose with a saltwater solution. This
may help reduce postnasal drip. You can purchase a saline solution at your
drugstore, or you can make your own at home.
