Why Does Postnasal Drip Make My Throat Hurt?

If you've ever had the sensation of mucus constantly dripping down the back of your throat, you know how annoying postnasal drip can be, and you’re not alone. It’s as common as the conditions that cause it, ranging from colds and allergies to structural issues like a deviated septum or nasal polyps.
Our team at Jacksonville ENT Surgery specializes in solving problems like chronic postnasal drip and the underlying issues that bring it on. We’re also happy to provide the information you need to make informed health decisions.
In this case, we’re happy to provide insight about postnasal drip, why it irritates your throat, and the treatments we use to eliminate the problem.
Understanding postnasal drip
Mucus-producing glands in the nose and throat help moisten the air you breathe, which your lungs prefer, and fight infection by filtering out bacteria, viruses, and other substances you inhale.
Unfortunately, infections, environmental pollutants, and other problems can cause excess mucus production. This mucus drains more than drips down your throat instead of being cleared out through your nose.
Postnasal drainage leads to symptoms such as:
- Sore or irritated throat
- A cough, often worse at night
- Frequent throat clearing
- Hoarseness
- Halitosis (bad breath)
- Nausea related to excess drainage
Postnasal drip is also a common trigger of middle ear infections caused by mucus building up and blocking the eustachian tubes.
How postnasal drip irritates the throat
Excess mucus related to postnasal drip can irritate the throat in many ways, including:
Constant contact with mucus
The tissues in your throat are sensitive, and prolonged exposure to thick or excessive mucus may lead to inflammation, resulting in soreness or a scratchy sensation.
Contact with acidic or irritating substances
The mucus produced during postnasal drip may contain inflammatory substances that irritate your throat. This is particularly common in allergic reactions or sinus infections.
Frequent throat clearing
Postnasal drip can lead to frequent, sometimes nearly constant, throat clearing. This repetitive action can strain throat muscles and lead to additional tissue irritation or pain.
Infections
If postnasal drip is caused by a bacterial or viral infection, such as a sinus infection or a cold, the same pathogens that affect your nasal passages can irritate your throat. The combination of infection-related inflammation and dripping mucus compounds the discomfort.
Treating postnasal drip
Home remedies may be all you need to soothe a throat irritated by postnasal drip. Our team recommends:
- Drinking plenty of water to help thin mucus so it’s easier to clear from your throat
- Using a saline nasal spray to clear excess mucus and reduce irritation
- Using a humidifier to help moisten the air and clear nasal passages
- Avoiding smoking, strong fragrances, dry air, and other common irritants
- Antihistamines or decongestants for allergies or sinus issues
If your sore throat or postnasal drip persists for more than a week, is accompanied by a fever, or if you notice thick yellow or green mucus, we recommend scheduling a visit.
Chronic postnasal drip may require specific treatments, such as allergy testing, prescription medication, or addressing underlying causes like acid reflux or a deviated nasal septum.
