What kind of doctor treats Viral Pharyngitis?

A primary care doctor, an internist (an adult doctor), or a pediatrician (a children's doctor) usually treats viral pharyngitis. An ear, nose, and throat doctor may help if sore throats keep coming back. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.

What is viral pharyngitis?

Viral pharyngitis is a sore throat caused by a virus. Pharyngitis is swelling in the throat at and just below the tonsils. It causes discomfort, pain, or scratchiness.

Most sore throats are caused by viruses. Viral pharyngitis can be part of a viral infection that also involves other organs, such as the lungs or bowel.

Symptoms

Symptoms may include:

  • Sore throat, which can feel dry and scratchy.
  • Discomfort or pain when swallowing.
  • Fever.
  • Joint pain or muscle aches.
  • Tender, swollen lymph nodes in the neck.

Some signs point to a virus instead of strep throat. These are a cough, a runny nose, hoarseness, and pink eye. Hoarseness means changes in your voice that make it sound breathy, raspy, or strained.

Causes and who gets it

Viruses, like those that cause colds or flu, are the most common cause of a sore throat. Other causes include strep bacteria, allergies, and smoking or secondhand smoke.

Sore throat can also be a symptom of strep throat, the common cold, or allergies.

How doctors diagnose it

A provider usually diagnoses viral pharyngitis by looking at your throat. The provider asks about your symptoms and does a physical exam.

Sometimes the provider swabs your throat. A lab test of fluid from your throat can show that strep bacteria are not the cause.

Treatment

There is no specific treatment for viral pharyngitis. Antibiotics will not help. Using them to treat viruses helps bacteria become resistant to antibiotics.

You can ease symptoms at home in these ways:

  • Gargle with warm salt water.
  • Drink warm drinks and plenty of fluids.
  • Suck on ice chips or popsicles.
  • Suck on lozenges, but do not give them to children younger than 4 years.
  • Use a clean humidifier or cool mist vaporizer.
  • Take acetaminophen or ibuprofen to control fever.

Using too much of a lozenge or spray that contains anti-inflammatory medicine may make a sore throat worse. For children, carefully read the label before you give any medicine. Children younger than 6 months should only get acetaminophen. Children 6 months or older can get acetaminophen or ibuprofen. Never give aspirin to children, because it can cause Reye's syndrome, a rare but very serious illness that can harm the liver and brain. Symptoms usually go away within 7 to 10 days.

When to see a doctor

Always get medical care if you have a sore throat with extreme discomfort or trouble swallowing. Also see a provider if you or your child has any of these:

  • Blood in saliva or phlegm.
  • Excessive drooling in young children.
  • Dehydration.
  • Joint swelling and pain.
  • A rash.
  • Symptoms that do not improve in a few days or that get worse.

A provider may test for strep throat. Tell your provider if you or your child gets sore throats again and again.

Call 911 or go to the emergency room if you have trouble breathing or swelling of the face, eyes, or tongue.

How a direct primary care or concierge doctor fits in

A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either kind of doctor can examine your throat, test for strep, and help you plan care at home. They can also follow up if symptoms do not improve.

Common questions

Does viral pharyngitis need antibiotics?

No, antibiotics will not help viral pharyngitis. They do not work on viruses. Using them to treat viruses helps bacteria become resistant to antibiotics.

How long does viral pharyngitis last?

Viral pharyngitis symptoms usually go away within 7 to 10 days. See a provider if they last longer than expected or do not get better with self-care.

How can I tell viral pharyngitis from strep throat?

A cough, runny nose, hoarseness, or pink eye can suggest a virus instead of strep throat. A virus and strep bacteria can cause similar symptoms, so a provider may swab your throat to check.

Can viral pharyngitis be prevented?

Most sore throats cannot be prevented, because the germs that cause them are in our environment. You can lower your risk by washing your hands, avoiding close contact with people who have sore throats, and not smoking. Also avoid kissing or sharing cups and eating utensils with people who are sick.

Is viral pharyngitis dangerous?

Usually not. Complications of viral pharyngitis are extremely uncommon. Still, get medical care for extreme discomfort or trouble swallowing, and call 911 for trouble breathing.
