Chronic Sore Throat

By Medically reviewed by hellodoktor


What is chronic sore throat?

A sore throat is pain, scratchiness or irritation of the throat that often worsens when you swallow. The most common cause of a sore throat (pharyngitis) is a viral infection, such as a cold or the flu. A sore throat caused by a virus resolves on its own.

A sore throat is normally a temporary symptom, fading away after a few days. A chronic sore throat is one which lasts longer than three or four weeks. If your sore throat persists and the symptoms become more prolonged, it can be a sign that you are suffering from a more severe illness.

How common is chronic sore throat?

Chronic sore throat can affect patients at any age. It can be managed by reducing your risk factors. Please discuss with your doctor for further information.


What are the symptoms of chronic sore throat?

A chronic sore throat is one which lasts longer than three or four weeks. A chronic sore throat may be accompanied by other signs and symptoms:

  • Changes in the voice, especially hoarseness
  • Painful swallowing (odynophagia)
  • Difficulty swallowing (dysphagia)
  • Chronic cough or constant clearing of the throat.

There may be some symptoms not listed above. If you have any concerns about a symptom, please consult your doctor.

When should I see my doctor?

If you have any signs or symptoms listed above or have any questions, please consult with your doctor. Everyone’s body acts differently. It is always best to discuss with your doctor what is best for your situation.


What causes chronic sore throat?

Some possible causes of a chronic sore throat include:

  • Tonsillitis (infection of the tonsils)
  • Strep throat
  • Allergies
  • Mononucleosis (also referred to as mono)
  • Inhaling air pollutants
  • Smoking
  • Influenza (the flu)
  • Inhaling through the mouth instead of the nose

Some of these conditions, like the flu, may be fairly minor and not require treatment, while strep throat and tonsillitis can turn into serious health problems if left untreated. Other causes of a chronic sore throat — like smoking — are problems that you can control to alleviate your throat pain. But if you’ve got a chronic sore throat and a cough that you can’t seem to get rid of on your own, with or without additional symptoms, it’s important to see your doctor about it.

Risk factors

What increases my risk for chronic sore throat?

There are many risk factors for chronic sore throat, such as:

  • Exposure to tobacco smoke. Smoking and secondhand smoke can irritate the throat. The use of tobacco products also increases the risk of cancers of the mouth, throat and voice box.
  • Allergies. Seasonal allergies or ongoing allergic reactions to dust, molds or pet dander, make developing a sore throat more likely.
  • Exposure to chemical irritants. Particles in the air from burning fossil fuels and common household chemicals can cause throat irritation.
  • Chronic or frequent sinus infections. Drainage from your nose can irritate your throat or spread infection.
  • Close quarters. Viral and bacterial infections spread easily anywhere people gather, whether in child care centers, classrooms, offices or airplanes.
  • Weakened immunity. You’re more susceptible to infections in general if your resistance is low. Common causes of lowered immunity include HIV, diabetes, treatment with steroids or chemotherapy drugs, stress, fatigue, and poor diet.

How is chronic sore throat diagnosed?

To diagnose, the cause is usually investigated. Identifying the cause depends on the other signs and symptoms present, apart from a sore throat, as well as considering the patient’s medical history. At times, other diagnostic investigation may be required. This may include a neck x-ray, CT scan or laryngoscopy.

How is chronic sore throat treated?

To find the best treatment for your sore throat, it is imperative that you find the culprit behind it. Sore throats caused by bacterial infections are treated with antibiotics. If you don’t treat the strep throat seriously it can cause serious complications like heart disease and valvular defects.

Antiviral medicines are used to treat a persistent sore throat that is caused by viral infections or you may get better without any treatment. If your sore throat is due to allergies, then you need medication to control the symptoms in addition to avoiding allergens to ease the symptoms and pain.

Lifestyle changes & Home remedies

  • Drink a lot of water and fluids to keep your throat hydrated. A warm tea with honey is recommended for more comfort.
  • Some cold foods like ice pops also provide relief to sore throats.
