Most throat pain comes from short‑term irritation or infection of the tissues in your throat, but there are a few more serious causes to know about.

Common reasons your throat hurts

  • Viral infections (most common).
    Colds, flu, COVID‑19, mono, and other viruses often cause sore throat along with a runny nose, cough, mild fever, or body aches. These usually improve on their own in about a week.
  • Strep throat and other bacteria.
    Strep throat is a bacterial infection that can cause sudden, intense throat pain, painful swallowing, fever, swollen tonsils with white patches, and swollen neck glands. It needs a test and usually antibiotics.
  • Dry air and mouth breathing.
    Heated or air‑conditioned indoor air, sleeping with your mouth open, or chronic nasal congestion can dry out your throat and make it feel scratchy or sore, especially in the morning.
  • Irritants (things that “burn” or inflame the throat).
    Cigarette or vape smoke, pollution, chemical fumes, dust, alcohol, and very spicy foods can irritate the lining of your throat and cause ongoing discomfort.
  • Overusing your voice.
    Yelling at a game, singing loudly, or talking for hours can strain the muscles in your throat and voice box, leading to soreness and hoarseness.
  • Allergies and postnasal drip.
    Allergies to pollen, dust, mold, or pets can cause mucus to drip down the back of your throat (postnasal drip), which keeps the tissues irritated and sore.
  • Acid reflux (GERD or “silent” reflux).
    Stomach acid that flows back up into your esophagus and throat can cause burning, a lump‑in‑the‑throat feeling, chronic cough, or hoarseness, sometimes without classic heartburn.
  • Less common causes.
    More rarely, throat pain can come from infections like HIV, fungal infections in people with weak immune systems, injury from very hot food or drinks, or tumors of the throat or voice box (often with persistent hoarseness, trouble swallowing, or a neck lump).

Simple things you can try at home

If your pain is mild and you feel otherwise okay, these can help while things heal:

  1. Drink plenty of fluids (water, herbal tea with honey, broths) to keep the throat moist and thin mucus.
  1. Use warm salt‑water gargles (about half a teaspoon of salt in a glass of warm water) a few times a day.
  1. Take over‑the‑counter pain relievers like acetaminophen or ibuprofen as directed, if you normally tolerate them.
  1. Use throat lozenges or sprays for temporary numbing relief (avoid lozenges in young children due to choking risk).
  1. Run a cool‑mist humidifier and avoid smoke or other irritants in the air.
  1. Rest your voice —avoid yelling or long phone calls if talking makes it worse.

When to get urgent help

Go to urgent care or the emergency department, or call emergency services, if you have:

  • Trouble breathing, noisy or high‑pitched breathing, or feeling like you can’t get enough air.
  • Trouble swallowing your own saliva, drooling, or inability to swallow fluids.
  • A stiff neck, severe headache, or feeling very unwell along with throat pain.
  • Sudden severe throat pain after swallowing something very hot, a chemical, or an object.
  • Significant swelling of the tongue, lips, or face (possible severe allergy).

When to see a doctor soon

Book a visit or telehealth appointment in the next day or two if:

  • Your sore throat lasts more than about a week or keeps coming back.
  • You have a fever, white spots on the tonsils, or very painful swallowing (you may need a strep test).
  • You have hoarseness that lasts longer than two weeks, especially if you smoke or drink heavily.
  • You have ongoing heartburn, sour taste in your mouth, or nighttime cough along with throat discomfort (possible reflux).

I can’t see or examine you, so I can’t tell you exactly why your throat hurts , but you can use the points above to match your symptoms and decide whether home care is enough or whether it’s time for an in‑person check.
