Sore Throat: what it usually means

Illustrative — the viruses behind most sore throats

The short answer: A sore throat is most often caused by a viral infection like a common cold, and it typically improves within a week with rest and simple home care. Pain, scratchiness, or difficulty swallowing are common and usually not serious. Difficulty breathing, being unable to swallow or drooling needs emergency services or an emergency department now; a sore throat that is severe, lasts beyond a week, or comes with a high fever should be checked, since it may need targeted treatment.

When to get medical help

A sore throat lasting more than a week without improvement should be evaluated.

Difficulty breathing, being unable to swallow, drooling, a high-pitched sound when breathing in, or symptoms that are severe and getting worse quickly — call emergency services now or go to an emergency department now.

A sore throat with a high fever, rash, or swollen glands warrants a doctor's visit.

White patches or pus on the tonsils may signal a bacterial infection needing treatment.

Recurrent sore throats without a clear cause deserve a medical review.

Common causes

  • Viral infections — Colds and flu are the most common cause of a sore throat and usually resolve on their own.
  • Strep throat — A bacterial infection can cause a sudden, severe sore throat, often with fever and no cough.
  • Allergies — Postnasal drip from allergies can irritate the throat and cause ongoing scratchiness.
  • Dry air or irritants — Breathing dry air, smoke, or strong fumes can leave the throat feeling raw.
  • Acid reflux — Stomach acid reaching the throat can cause a chronic sore or burning sensation.

What helps

  • Gargle with warm salt water a few times a day to ease discomfort.
  • Drink warm fluids and stay well hydrated.
  • Use throat lozenges or a humidifier to soothe irritation.
  • Rest your voice and avoid smoke or other irritants.
