What is a sore throat?
A sore throat (pharyngitis) is a painful, scratchy feeling caused by inflammation at the back of the throat. It may result from viral or bacterial infections, allergies, or even sleeping with your mouth open. Unlike temporary dryness from dehydration or talking too much, a persistent sore throat can signal infection or irritation that needs closer attention.
Sore throat symptoms can vary depending on the cause, but often include:
-
Pain or a scratchy feeling in the throat
-
Pain when swallowing or talking
-
Difficulty swallowing
-
Swollen glands in the neck or jaw
-
Red or swollen tonsils
-
White patches or pus on the tonsils
-
A hoarse or muffled voice
-
If an infection is the cause, you may also experience: fever, cough, runny nose, sneezing, body aches, and headache.
⚠️ Contact your healthcare provider if your sore throat lasts more than a week or if you experience severe pain, difficulty breathing or swallowing, fever (over 38°C), a visible bulge in your throat, blood in saliva or phlegm, or a body rash.

Tips for relieving a sore throat at home
Most sore throats can be managed with simple, safe remedies:
Most sore throats are caused by viruses and usually improve on their own within 5–7 days. In these cases, antibiotics won’t help — but there are simple ways to ease discomfort while your body recovers.
Here are safe and effective ways to feel better at home:
-
Stay hydrated
Drink plenty of fluids, especially warm beverages like tea or broth, to soothe irritation and keep your throat moist. -
Use salt water gargles
Gargling with warm salt water can help reduce swelling and ease pain. -
Try soothing options
Ice chips, popsicles, or lozenges can provide relief (avoid lozenges for children under 4). Honey may also help calm irritation and cough in adults and children over 1 year old. -
Use a humidifier
A clean humidifier or cool mist vaporiser can add moisture to the air and prevent further throat dryness. -
Rest your voice
Give your voice time to recover if your sore throat is caused by talking, shouting, or singing. -
Avoid irritants
Stay away from secondhand smoke, spicy foods, and very hot liquids. If you smoke, consider speaking with a healthcare provider about quitting. -
Consider over-the-counter pain relief
Mild pain relievers such as acetaminophen or ibuprofen may help reduce pain and fever. Always follow usage instructions and choose child-specific options for infants or children, and speak with your doctor or pharmacist if you're unsure which option is right for you or your child. -
Other treatments may help depending on the cause
Some sore throats may need additional treatment depending on the cause. Antibiotics can treat bacterial infections, while antihistamines may help with allergy-related postnasal drip and antacids with acid reflux. In severe cases, a healthcare provider may prescribe a medicated mouthwash. If symptoms persist or worsen, speak with a healthcare professional, as treatment depends on the underlying cause.

What causes a sore throat?
Most sore throats are caused by viral infections like the common cold or flu.
Sometimes, they can be caused by other things, including:
-
Bacterial infections (like strep throat or sinus infections)
-
Tonsillitis (inflamed tonsils caused by viruses or bacteria)
-
Allergies (from pollen, dust, pets, or mould causing mucus to drip down the throat)
-
Acid reflux (stomach acid moving up into the throat)
-
Strain or irritation (from yelling, smoking, spicy foods, or very hot drinks)
-
Mouth breathing, especially during sleep
Rarely, an ongoing sore throat can be linked to growths in the throat, including cancer.
