I Have a Chronic Sore Throat That Won't Go Away

A sore throat that lingers for weeks can be frustrating and concerning. Here is what could be behind it.

A sore throat that lasts more than a few weeks is called chronic pharyngitis. Most cases are not cancer.

  • Common causes include:
  • Post-nasal drip β€” allergies or sinus infections causing mucus to irritate the throat
  • GERD (acid reflux) β€” stomach acid reaches the throat, causing persistent irritation
  • Tonsil stones β€” small calcified deposits in the tonsil crevices that cause discomfort
  • Mouth breathing β€” especially at night, dries out the throat
  • Smoking or vaping β€” chronic chemical irritation
  • Allergies β€” seasonal or environmental allergies
  • Voice overuse β€” straining your voice regularly

Less commonly, a chronic sore throat could be related to tonsil cancer or throat cancer, especially if it is on one side.

What to Look For

  • Usually not serious:
  • Sore throat that is worse in the morning or at night
  • Improves with hydration and rest
  • Associated with allergies or reflux
  • Both sides feel equal
  • Comes and goes
  • Worth having checked:
  • Sore throat on one side only that does not go away
  • Persistent sore throat with ear pain on the same side
  • A visible lump or swelling in the throat or neck
  • Difficulty swallowing
  • Hoarseness that accompanies the sore throat
  • Coughing up blood

When to See a Doctor

  • See an ENT doctor if:
  • Your sore throat has lasted more than 3 weeks
  • It is on one side only
  • You have ear pain on the same side
  • You have a lump in your neck
  • You have trouble swallowing or a change in your voice
