Sore Throat
Pain, scratchiness, or irritation of the throat.
TL;DR
Most sore throats are viral, peak within 2-3 days and resolve within a week — antibiotics neither shorten them nor prevent complications in most cases. The features that matter: fever without cough or runny nose, pus on the tonsils and tender neck glands suggest strep; one-sided severe pain with muffled voice or difficulty opening the mouth suggests abscess — same-day review. Honey, warm salt-water gargles and simple painkillers are the best-evidenced self-care.
Overview
A sore throat — pain, scratchiness or rawness that is often worst on swallowing — is one of the most common symptoms in medicine, and the vast majority are viral and self-limiting, resolving within a week regardless of treatment. The clinical challenge is not treating the typical sore throat but recognising the minority that need more: streptococcal infection, peritonsillar abscess, glandular fever, and the persistent sore throat that occasionally signals something serious.
Common Symptoms
- •Pain or scratchiness, typically worst on swallowing
- •Dry, raw sensation with or without visible redness
- •Swollen, tender glands in the neck
- •Hoarseness or voice change
- •Fever, headache and body aches in more significant illness
- •White patches or pus on the tonsils in bacterial infection
- •Difficulty swallowing or drooling in severe cases — a red flag
Common Causes
- •Viral infections — common cold viruses, flu, COVID-19, glandular fever
- •Streptococcus pyogenes — the main bacterial cause, commonest in children
- •Post-nasal drip from colds, allergies or sinusitis
- •Dry air, mouth breathing and snoring
- •Acid reflux — morning sore throat with hoarseness
- •Smoke, vaping and air pollution
- •Strain from shouting or prolonged voice use
- •Rarely: epiglottitis, peritonsillar abscess, tumours in persistent cases
Root Causes
Throat pain arises from inflammation of the pharyngeal lining: viruses invade the mucosa directly, provoking prostaglandin and cytokine release that sensitises local pain nerves, while streptococci trigger a more intense pus-forming response. Swallowing then mechanically stimulates these inflamed, sensitised tissues — which is why sore throat hurts most precisely when you swallow. Post-nasal drip and mouth breathing dry and irritate the mucosa mechanically, and reflux bathes it in acid overnight, explaining the characteristic morning pattern.
How It's Diagnosed
Diagnostic Markers
- Usually none — viral sore throat is a clinical, self-limiting diagnosis
- Centor criteria guide strep testing: fever, tonsillar pus, tender neck glands, absence of cough
- Rapid strep test or throat swab where bacterial infection is likely
- Glandular fever blood test when fatigue and swollen glands persist beyond two weeks
- Persistent unilateral symptoms or hoarseness beyond three weeks — specialist examination of the throat
When to See a Doctor
{"Severe one-sided pain with muffled (hot potato) voice or difficulty opening the mouth","Drooling, inability to swallow fluids, or any difficulty breathing — emergency","Sore throat persisting beyond one week without improvement","Hoarseness lasting more than three weeks","Recurrent severe episodes — five or more in a year","Sore throat with rash, joint pain or dark urine after a strep picture","Immunosuppression with significant throat symptoms"}
Supplements Studied For This
Marshmallow Root
A coating demulcent is exactly the right tool for a raw throat, and marshmallow is the classic one. Relief is real but short-lived and purely symptomatic.
Propolis
A reasonable soothing option for a scratchy throat if you are not allergic to bee products; not a substitute for treating bacterial pharyngitis.
Probiotics
Sensible for recurrent throat infections using oral-colonizing strains; mostly irrelevant for the drip/reflux causes of chronic sore throat.
Slippery Elm
A physically plausible, regulator-recognized demulcent for symptom relief — just do not expect trial-grade evidence.
Diet & Lifestyle
Suggested Pattern
Swallowing-friendly textures matter more than any specific food during the acute phase: warm (not hot) liquids soothe, cold items like ice lollies numb, and both have their advocates. Adequate fluid intake keeps the mucosa moist and thins secretions. Honey — a teaspoon straight or in warm water — has randomised-trial support for reducing symptom severity in adults and children over one year.
Eat more
- Warm fluids — soups, broths, herbal teas with honey
- Soft, easy-to-swallow foods — porridge, yoghurt, mashed vegetables
- Honey — genuine trial evidence for symptom relief (over 1 year of age only)
- Cold items — ice lollies or frozen yoghurt for numbing relief
- Adequate overall fluids to keep the mucosa moist
Avoid
- Acidic juices and fizzy drinks that sting inflamed tissue
- Very hot drinks and food — soothing warmth, not scalding
- Rough, scratchy textures — crisps, dry toast, crackers
- Alcohol and smoking, both directly irritating
- Dairy avoidance is a myth — it does not increase mucus production

Who It Affects
Sore throat accounts for around 1-2% of all primary care consultations and virtually everyone experiences episodes — adults average two to three viral upper respiratory infections per year, children six to eight.
Most common in children aged 5-15 for streptococcal infection, and in anyone with close household contact of cases. Smokers, people with allergies and those with reflux have more frequent non-infective throat symptoms. Persistent hoarseness and sore throat in older smokers carries the most diagnostic weight.
Quick Facts
- •Around 70-90% of adult sore throats are viral
- •Symptoms typically peak at day 2-3 and resolve within a week
- •Strep accounts for roughly 15-30% of cases in children, 5-15% in adults
- •Antibiotics shorten strep throat by only about a day on average
- •Honey has genuine trial evidence for symptom relief in over-1s
- •One-sided severe pain with a muffled voice is a same-day presentation
Lifestyle Tips
- •Gargle warm salt water — half a teaspoon of salt in a glass — several times daily
- •Rest your voice rather than whispering, which strains it more
- •Humidify dry bedroom air, especially if you snore or mouth-breathe
- •Treat post-nasal drip — saline nasal rinses address a common hidden driver
- •Do not smoke, and avoid smoky environments while symptomatic
- •Honey before bed reduces night coughing that aggravates the throat
