Burning Throat: Causes, Remedies and When to Worry

Quick answer

Reflux and infection lead the list; persistent burning needs a check

The most frequent causes are acid reflux (including silent reflux, LPR), colds and other viral infections, strep throat, allergy and postnasal drip, smoke and chemical irritants, spicy food, alcohol and dry air. Antacids, smaller and earlier meals, avoiding trigger foods, staying hydrated and quitting smoking help when reflux is the cause; fluids, rest and pain relief help infections. Burning that lasts more than 3–4 weeks, burning with hoarseness, trouble or pain swallowing, weight loss or a neck lump should be assessed by a doctor or ENT specialist.

Important. Burning in the throat or chest with pressure, pain spreading to the arm or jaw, breathlessness, sweating or fainting needs emergency care, because it can be a heart problem. Difficulty breathing or swallowing, drooling, swelling of the lips or tongue, or coughing blood also need urgent help.

Why does the throat burn?

The lining of the throat and voice box is very sensitive. Anything that inflames or chemically irritates it, from stomach acid to a virus, can produce a raw, burning or scalding sensation, often with soreness, a feeling of a lump or a need to clear the throat. Because the oesophagus and throat sit side by side, a burn felt in the throat can come from either.

Acid reflux and silent reflux

Reflux of stomach contents up the oesophagus (GERD) causes heartburn behind the breastbone, and may reach the throat, leaving a sour taste, a burning sensation and hoarseness. In laryngopharyngeal reflux (LPR), small amounts of reflux reach the voice box and throat, often without heartburn, causing burning, throat clearing, a lump sensation and a chronic cough. Burning that is worse after meals, when lying down or in the morning points to reflux. See LPR and acidez de estómago (Spanish).

Infections

Viral pharyngitis (colds, flu, COVID-19): burning or scratchy throat, then a sore throat, often with cough, runny nose and fever. See pharyngitis.
Strep throat and bacterial tonsillitis: sudden severe pain with fever and swollen tonsils. See strep throat.
Oral or oesophageal thrush (candida): a burning mouth or throat with white patches, most often in people using inhaled steroids, antibiotics or with a weak immune system.
Herpes and other viral infections, which can cause painful ulcers.

Irritants, allergies and lifestyle

Smoking, vaping and second-hand smoke.
Alcohol and very hot, spicy or acidic foods and drinks.
Dry air, mouth breathing and dehydration.
Allergies and postnasal drip, where mucus trickles down the throat and irritates it.
Chemical fumes, cleaning products and air pollution.
Voice overuse and shouting.
Medicines that irritate the oesophagus when swallowed with too little water (some antibiotics, bisphosphonates, iron, potassium tablets, anti-inflammatories).

What can soothe it

For reflux: eat smaller meals, avoid eating within three hours of bedtime, raise the head of the bed, reduce fatty food, coffee, chocolate, mint, alcohol and tomato-based dishes, and lose excess weight.
Antacids or alginates give short-term relief of reflux symptoms; ask a pharmacist for advice.
Fluids: sip water or warm (not hot) drinks; honey in warm tea soothes the throat (not for babies under one).
Humidify the bedroom and avoid dry, heated air.
Avoid smoke, alcohol and spicy foods until the burning settles.
Saline nasal rinse if postnasal drip is the trigger.
Take pills with a full glass of water and stay upright afterwards.

Medical treatment

If reflux is likely and symptoms persist, a doctor may recommend a trial of a proton pump inhibitor for several weeks, together with the lifestyle changes above, and review the response. Infections are treated according to the cause: antibiotics for confirmed strep, antifungals for thrush, supportive care for viruses. Allergy treatment (antihistamines, nasal steroid sprays) helps drip-related burning. If symptoms do not respond or alarm features are present, an ENT or gastroenterology assessment, with a camera examination of the throat and voice box or an endoscopy, may be needed.

When burning is not the throat

Angina and heart attack can be felt as burning, tightness or pressure in the chest, neck, jaw or throat, particularly with exertion. Features that point to the heart include pain spreading to the arm or jaw, breathlessness, sweating, nausea or a feeling of impending doom, particularly in people over 40 or with risk factors such as smoking, diabetes, high blood pressure, high cholesterol or a family history. When in doubt, call emergency services.

When to see a doctor

Burning for more than 3–4 weeks, or recurring often.
Hoarseness lasting more than four weeks.
Difficulty or pain swallowing, food sticking or vomiting.
Unexplained weight loss, black stools or anaemia.
A lump in the neck or coughing blood.
Burning in smokers or heavy drinkers that does not clear.
Chest pain or breathlessness (urgent).

Three common situations

Burning in the throat after large evening meals, with a sour taste: likely reflux; change meal timing and size and try an antacid.

Burning, scratchy throat with sneezing and runny nose: a cold or allergy; fluids, saline rinses and rest.

Burning throat for two months with hoarseness in a smoker: needs an ENT examination of the voice box.

Key points to remember

Most burning throats come from reflux, infection or irritants and improve with simple measures. Do not ignore burning that lasts for weeks or comes with warning signs. Our ENT team can examine your throat and arrange the right tests.

Questions about a burning throat

These answers are general information and do not replace an examination or individual medical advice.

Why does my throat burn when I swallow?

Inflammation from infection or reflux irritates the lining; a burn on swallowing can also come from the oesophagus.

Can acid reflux make my throat burn without heartburn?

Yes. Silent reflux (LPR) often causes throat burning, throat clearing and hoarseness without heartburn.

How can I soothe a burning throat fast?

Sip cool or warm fluids, use honey, humidify the air, and take an antacid if reflux is likely.

Is a burning throat a sign of Covid or a cold?

It can be an early sign of viral infections, usually with other symptoms such as cough, runny nose or fever.

Can anxiety cause a burning throat?

Anxiety can cause throat tightness and discomfort, but physical causes such as reflux should be checked.

When should I worry?

If it lasts more than 3–4 weeks, comes with trouble swallowing, hoarseness, weight loss, or with chest pain.
