You May Have Postnasal Drip
One of the most common reasons people constantly clear their throat is postnasal drip.
This happens when mucus produced in the nose or sinuses drains backward toward the throat.
You may not always feel mucus coming directly from your nose. Instead, you might notice:
Constant throat clearing
A sensation of mucus stuck in the throat
Coughing, especially at night
A runny or stuffy nose
Frequent swallowing
A feeling of something dripping down the back of your throat
