Cobblestone Throat Causes and Treatment

Medically reviewed by Brian Bezack, DOMedically reviewed by Brian Bezack, DO

Cobblestone throat describes the bumpy, cobblestone-like texture of inflamed tissue in the back of the throat. The bumps are sometimes mistaken for throat cancer, however, cobblestone throat is not dangerous and is usually a harmless result of a minor problem such as a viral infection, postnasal drip, or breathing in dry air.

Cobblestone throat is a symptom rather than a condition, so it usually goes away once the underlying cause resolves. While home remedies will not cure the underlying cause, they can help relieve the soreness, hoarseness, and other symptoms that often come with cobblestone throat.

What Is Cobblestone Throat?

Cobblestone throat is caused by enlarged lymphatic tissue in the tonsils and adenoids, which are glands in the back of the nasal passage that help filter out bacteria and viruses.

These lymphatic tissues swell as part of an immune response to extra mucus in the back of the throat, leading to the formation of bumps. The bumps take on the appearance of a cobblestone road, hence the term "cobblestone throat."

Healthcare providers sometimes use the term when referring to pharyngitis or sore throat. Pharyngitis can either be an acute (short duration) symptom, or chronic (lasting 12 weeks or more).



When is a sore throat an emergency?

Seek immediate medical attention if your sore throat develops with severe symptoms like:



Acute Pharyngitis

With acute pharyngitis, pain and inflammation develop quickly and can occur with or without drainage. In many cases, inflammation and sore throat are stand-alone symptoms that can last for up to two weeks. Acute pharyngitis is often caused by viral or bacterial infections.

Chronic Pharyngitis

Chronic pharyngitis is a sore throat that lasts longer than 12 weeks. The discomfort associated with a chronic sore throat can also come and go over time. Recurrent viral and bacterial infections can cause chronic sore throat. However, chronic conditions like allergies, acid reflux, and chronic mouth breathing are more often to blame. Although rare, sore throat can also be a sign of head and neck cancer.



Other Causes of Sore Throat

Some less common but sometimes more serious causes of sore throat include:

  • Cancer: Including Kaposi sarcoma (cancer of gastrointestinal tissues) and leukemia

  • Gastroesophageal reflux disease (GERD): A more severe form of acid reflux

  • Peritonsillar abscess: Pus-filled tissue at the back of the mouth, near the tonsils

  • Diphtheria: A serious bacterial infection

  • Epiglottitis: A life-threatening infection in the vocal cords

  • Herpes simplex virus: A virus causing oral and genital herpes

  • Mononucleosis: A contagious infection caused by Epstein-Barr virus




Cobblestone Throat Symptoms

Cobblestone throat often occurs with other symptoms, such as:

  • Sore throat

  • Dry, scratchy throat

  • Pain when swallowing

  • Pain when speaking

The symptoms you experience depend on the underlying cause.

For example, cobblestone throat that occurs without a cough or nasal congestion most likely points to a bacterial infection. On the other hand, a viral infection is more likely to cause fatigue, muscle aches, headache, and fever in addition to cobblestone throat.



Cobblestone Throat vs. HPV

Human papillomavirus (HPV) can sometimes infect the throat, but HPV does not cause cobblestone-like bumps. While an oral infection of HPV can cause a sore throat, visible lesions usually appear as white or red patches or as a lump in the neck.



What Causes Cobblestone Throat?

A stuffy nose with postnasal drip, a leaking of nasal drainage down the back of your throat, can cause a cobblestone effect. Bacterial and viral infections like strep throat, colds, and influenza cause the most cases of pharyngitis, but some other common causes include:

  • Allergies

  • Acid reflux

  • Smoking or vaping

  • Breathing dry air

  • Dehydration

  • Drinking hot liquids



Can stress cause cobblestone throat?

Stress doesn't cause cobblestone throat, but it can contribute to some of the conditions that cause cobblestone throat. For example, stress may cause you to adopt unhealthy habits such as poor hydration, which may lead to throat pain, inflammation, and cobblestone throat.



Could It Be COVID-19?

Cobblestone throat has been reported as a symptom of COVID-19. However, each variant of the illness has unique symptoms, and not all include a sore, cobblestone throat. The same variant can cause different symptoms in each infected person.

Redness and inflammation of the throat can occur with the COVID-19 illness or from coughing brought on by the illness. It's important to rule out other causes, too. Your healthcare provider may test you for COVID-19 and influenza (the flu), strep throat, or respiratory syncytial virus (RSV) when making a diagnosis.

Is Cobblestone Throat Contagious?

Cobblestone throat is a symptom, so it is not contagious in itself. However, some of the conditions that lead to cobblestone throat are contagious. Bacterial infections like strep and viral infections like COVID-19 can all be passed from person to person.

If you don't know what caused your symptoms, it is best to stay home until they resolve to avoid potentially spreading your condition to other people.

When to See a Healthcare Provider

An acute sore throat can last up to two weeks, while chronic infections last longer. If your sore throat lingers for more than a few weeks or worsens over time, you should make an appointment to see a healthcare provider.

See a healthcare provider right away if you have trouble swallowing or speaking, if your throat is swollen, or if you are coughing up blood.

Your healthcare provider may be able to diagnose the cause of your symptoms with a simple throat exam. If they suspect a bacterial infection, they may take a throat culture or give you a rapid strep test.

A sore throat that doesn't go away or includes unusual symptoms could be a sign of more serious problems like throat cancer or GERD.

Cobblestone Throat Treatment

There isn't a specific treatment for cobblestone throat. Since it manifests as a symptom of another underlying condition, it will go away once that underlying condition resolves.

In the meantime, over the counter (OTC) pain-relief medications like Tylenol (acetaminophen) or Advil or Motrin (ibuprofen) may be used to control pain and swelling.

A viral infection usually clears on its own, although healing may take a few weeks. If a bacterial infection like strep throat causes inflammation and swelling, your provider will likely prescribe antibiotics to resolve the infection.



How long does cobblestone throat last?

Pharyngitis, which can give your throat a cobblestone appearance, can last for two weeks, but in some cases, it may linger for longer. Your healthcare provider can help you identify a cause and find proper treatment.



Home Remedies

Whether your sore throat is caused by a viral or bacterial infection, or something else, there are several home remedies you can try to ease your discomfort:

  • Drinking plenty of fluids can thin mucus and treat postnasal drip

  • Drink tea or warm liquids with honey

  • Suck on hard candy or lozenges

  • Use a humidifier to add moisture to the air

  • Gargle with salt water

  • Gargle with water and a dash of cayenne pepper, which contains an anti-inflammatory compound called capsaicin

Prevention Tips

You can't avoid every infection, but there are a number of things you can do to reduce your risk of developing pharyngitis. This includes:

Summary

A sore throat can take on a cobblestone appearance, with redness and swelling. Sore throats can be caused by bacterial or viral infections or result from other illnesses or irritations. Talk to your healthcare provider if your sore throat isn't getting better after two to three weeks.
