Cobblestone Throat: Bumps on the Back of Your Throat

Cobblestone throat means there are small bumps on the back of your throat. These bumps are immune system tissue that swells from ongoing irritation, usually from postnasal drip, allergies or acid reflux, but sometimes from a cold or strep throat.

Cobblestone throat isn’t dangerous, and the bumps go away once you treat the cause. See a doctor if your sore throat lasts more than a week, you have trouble swallowing, or you notice a lump on one side. Get emergency care right away for trouble breathing.

What Is Cobblestone Throat?

Cobblestone throat is a pattern of small bumps along the back wall of your throat. These bumps are immune tissue (lymphoid tissue), swollen from ongoing irritation. Doctors call this “cobblestoning,” and it’s a sign rather than a disease.

The bumps aren’t growths or tumors, and they fade once the irritation stops. A sore throat from a cold usually clears within about a week.² Reflux or allergy bumps can last or come back as long as the irritation continues.

Is Cobblestone Throat Dangerous or Contagious?

Cobblestone throat isn’t dangerous on its own, and the bumps themselves aren’t contagious. But the cause might be, since you can spread a cold, the flu or strep throat to others. Other causes, like allergies, acid reflux or smoke, aren’t.

Cobblestoning is a harmless reaction to irritation and doesn’t turn into cancer, but how your throat looks can’t rule out HPV (human papillomavirus) or cancer. Throat cancer can show up as a sore that doesn’t heal, lasting throat pain or hoarseness, trouble swallowing or a neck lump. Other problems can cause these signs too.

What Does Cobblestone Throat Look Like?

Cobblestone throat means you have bumps on the back of your throat, behind the uvula (the flap at the back of your mouth). The bumps are usually small, round, and pink or red. They make your throat look lumpy.

Bumps That Look Similar

It’s possible to mistake cobblestone throat for the normal bumps on the back of your tongue, which sit lower and farther forward. Other look-alikes include:

Cobblestone Throat Symptoms

Along with cobblestone throat, you’ll usually have a sore or irritated throat. Other symptoms depend on the cause and may include:

• The feeling of something stuck in your throat.
• Frequent throat clearing or a tickly cough.
• Mucus in the back of your throat.
• Hoarseness.
• Soreness that makes it hurt to swallow.

Cobblestoning doesn’t always make your throat sore. Pain on one side of your throat may have another cause, so get it checked if it’s severe or doesn’t go away.

Common Causes of Cobblestone Throat

Cobblestone throat is caused by ongoing irritation, usually from postnasal drip, allergies or acid reflux. Other common causes include colds, strep throat, smoke and dry air.

Postnasal Drip

Postnasal drip means extra mucus from your nose or sinuses is draining down your throat. This mucus can make the lymphoid tissue swell, even without an infection. Common causes include:

• Colds and sinus infections.
• Cold air and weather changes.
• Spicy foods and certain medications.

Allergies

Allergies make your nose produce excess mucus, which drains down your throat. If your symptoms come and go (with the seasons or around pets), allergies may be the cause. Common allergens include:

• Pollen.
• Dust mites.
• Pet dander.
• Mold.

Acid Reflux and LPR

Laryngopharyngeal reflux (LPR) means stomach contents come up into your throat and voice box. Unlike regular acid reflux, LPR often doesn’t cause heartburn. Symptoms include:

• Hoarseness
• Frequent throat clearing
• Too much mucus or a lump feeling in your throat

Colds and Other Infections

Viruses are the most common cause of sore throats, including colds, the flu, COVID-19 and mononucleosis. Sore throat is a common COVID-19 symptom, but cobblestoning isn’t.

Group A strep bacteria cause about 20% to 30% of sore throats in children and 5% to 15% in adults.⁷ The only way to know is with a strep test.

Less often, sexually transmitted infections such as gonorrhea can spread to the throat during oral sex.

Smoke and Other Irritants

Anything that dries or irritates your throat’s lining can keep it swollen, including:

• Smoking, vaping, or secondhand smoke
• Dry indoor air
• Mouth breathing while you sleep
• Pollution or chemical fumes

Other conditions can also cause a dry throat.

Treatment Options for Cobblestone Throat

Cobblestone throat goes away once you treat the cause, so your doctor will first figure out what it is.

Finding the Cause

A cough, runny nose or hoarseness points to a virus, while fever, swollen neck glands and white tonsil patches without a cough suggest strep. These strep signs, called the Centor criteria, help doctors decide who needs a strep test. Tests include:

• A quick strep test with results in minutes, or a throat culture, which takes a day or two. For kids 3 and older, a culture is usually done if the quick test is negative.⁷
• An exam of your throat and voice box with a thin, lighted tube, usually by an ear, nose, and throat (ENT) doctor, if your hoarseness or reflux symptoms last.

Treating the Cause

• Postnasal drip or allergies: Saline rinses, antihistamines, steroid nasal sprays, and avoiding your triggers. For nasal rinses, use only distilled, sterile, or boiled and cooled tap water.
• Acid reflux: Eating smaller meals, not eating for 2-3 hours before bed, and raising the head of your bed, plus acid-reducing medicine.
• Strep throat: Antibiotics if you test positive, usually penicillin or amoxicillin, taken for the full course.
• Viral infections: Rest and plenty of fluids, since antibiotics don’t help.
• Smoke or dry air: Quit smoking or vaping, and use a humidifier.

Home Remedies for Cobblestone Throat

These steps won’t clear the bumps, but they can soothe a sore throat while you treat the cause:

• Gargle with warm salt water.
• Drink plenty of fluids to keep mucus thin.
• Add honey to warm tea to help a cough (never give it to a baby under 1).
• Take acetaminophen or ibuprofen as the label directs.

Foods and Drinks

• Have warm broth or caffeine-free tea.
• Try ice pops or yogurt.
• Stick to soft foods and avoid spicy, acidic, or crunchy ones.

Lozenges and Humidity

• Suck on lozenges or hard candy to keep your throat moist. Don’t give them to kids under 4, since they’re a choking hazard.²
• Use a cool-mist humidifier, and clean it regularly to prevent mold growth.

When to See a Doctor

See a doctor if your sore throat is severe or lasts longer than a week.⁸ Take your child to a doctor if their sore throat doesn’t go away after their first drink in the morning. Start with your primary care doctor or an urgent care clinic.

Call 911 or Go to the ER

Get emergency care right away for:

• Trouble breathing
• Being unable to swallow liquids or your own saliva, or drooling
• Throat pain that’s severe and getting worse quickly
• Swelling in your throat, neck or face that’s getting worse quickly
• A swollen or painful eye, vision changes or a lot of swelling inside your mouth

Call 911 if swelling makes it hard to breathe or swallow.

Call a Doctor Right Away

• New trouble opening your mouth with a sore throat

Call your baby’s doctor right away for a fever of 100.4°F (38°C) or higher in a baby 3 months or younger. A rectal reading is most accurate at this age, but don’t delay calling to take one.

Make an Appointment If You Have

• A fever higher than 101°F (38.3°C)
• White patches on your tonsils or swollen, tender glands in your neck, which may need a strep test
• Hoarseness lasting more than two weeks
• A lump in your neck
• Blood in your saliva or phlegm
• An earache, rash or joint pain with a sore throat
• Sore throats that keep coming back
• Bumps that haven’t improved in one to two weeks, even without soreness, or that come back after treatment
• One lump, a sore that doesn’t heal, or swelling on one side of your throat

For lasting hoarseness, reflux symptoms or bumps, your doctor may refer you to an ENT specialist.
