Our noses are lined with a wet, sticky mucus. It helps to trap particles and pathogens to prevent them from entering into the lungs where they might otherwise do us harm.
We make about one quart of nasal mucus every day and the excess usually runs down the back of the throat where it is then swallowed.
Post nasal drip is a common condition where the patient experiences an increase in the volume of this mucus, or that the mucus becomes thicker. This will often result in a runny nose but sometimes this excess mucus can end up running down the back of the throat. This is a condition known as post nasal drip and it can cause various symptoms.
Symptom #1: Sore Throat
The tissues at the back of the throat are quite delicate. They are usually well protected, though, meaning that harm is unlikely to come to them by physical means. Still, they can become susceptible to certain illnesses and the throat can become quite painful as a result.
A common symptom of a postnasal drip is a sore throat. Many patients will also describe it as feeling scratchy. While it can be quite uncomfortable and can make drinking and eating difficult, it will pass harmlessly in time. Remedies are available that can at least reduce the severity of the symptoms.
