Painful swallowing

Overview

Painful swallowing, also called odynophagia, is a sharp, burning, or stinging feeling when you swallow food, drink, or even saliva. It can make eating and drinking uncomfortable or difficult.

Yes, painful swallowing is a very common symptom, especially during colds, flu, or after a bad cough. Most people experience it at some point.

It can affect anyone at any age, but it is more common in people with weakened immune systems, those who smoke, or those who have acid reflux. Children often get it with viral infections.

Symptoms

Common symptoms

• A sharp or burning pain in the throat or chest when swallowing
• A feeling that food is stuck in the throat or chest
• Sore throat, especially when swallowing
• Cough, hoarse voice, or runny nose
• Mild fever or feeling generally unwell

Symptoms in children

• Refusing to eat or drink
• Crying or fussing during feeding
• Drooling more than usual
• Complaining of a sore throat or pain when swallowing

Symptoms in older adults

• Unexplained weight loss from avoiding food
• Increased risk of dehydration because drinking hurts
• Silent reflux (no heartburn) causing throat irritation
• Difficulty swallowing pills

Causes

Main causes

• Viral infections like the common cold, flu, or glandular fever
• Bacterial infections such as strep throat (streptococcal pharyngitis)
• Acid reflux (gastroesophageal reflux disease or GERD), where stomach acid flows back into the esophagus
• Irritation from smoking, alcohol, or very hot/spicy foods
• Inflammation of the esophagus (esophagitis) from allergies or medications

Risk factors

• Smoking or vaping
• Drinking alcohol often
• Having a weakened immune system (for example, from another illness or treatment)
• Taking certain medications that can irritate the esophagus (like aspirin or some antibiotics) without enough water
• Untreated acid reflux

When to see a doctor

See a doctor urgently if:

• If you have any of the emergency symptoms listed above
• If you cannot swallow any liquids at all

Book a routine appointment if:

• If the pain lasts longer than a week without getting better
• If you have a fever that lasts more than 3 days
• If you keep getting painful swallowing again and again
• If you have unintentional weight loss

Diagnosis

A doctor will ask about your symptoms and examine your throat, neck, and perhaps your ears and nose. They may use a light and a small mirror to look at the back of your throat.

Tests that may be done

• A throat swab to check for bacterial infections like strep throat
• A blood test if an infection like glandular fever is suspected
• An endoscopy (a thin, flexible camera down your throat) if symptoms last a long time or are severe
• A barium swallow test (drinking a chalky liquid and having X-rays) to check for blockages or structural problems

What to expect at your appointment

The visit is usually quick and simple. You may be asked to open wide and say 'ahh'. The doctor might press gently on your neck. Most tests are not painful, though a throat swab can make you gag for a moment.

Treatment

Treatment depends on the cause. For many viral infections, rest and home care are enough. For bacterial infections, antibiotics may be needed. For acid reflux, medicines that reduce stomach acid can help. Pain relief can make swallowing more comfortable.

Self-care at home

• Drink warm liquids like tea with honey or soup to soothe your throat
• Eat soft, easy-to-swallow foods like yogurt, mashed potatoes, or smoothies
• Avoid very hot, spicy, acidic, or crunchy foods that can irritate
• Suck on ice chips or frozen treats to numb the pain
• Gargle with warm salt water (half a teaspoon of salt in a glass of water) several times a day

Medical treatments

If an infection is bacterial, your doctor may prescribe antibiotics. For acid reflux, they may recommend antacid medicines or acid-reducing tablets available over the counter. Pain relievers can help with discomfort. Always follow the advice of your healthcare provider.

When is surgery considered?

Surgery is rarely needed. It may be considered if there is an abscess (a pocket of pus) in the throat that needs draining, or if there is a narrowing (stricture) in the esophagus that does not get better with other treatments.

Living with this condition

While you recover, take things slowly. Eat small, frequent meals that are easy to swallow. Keep a glass of water nearby and sip often. Avoid talking too much if your throat is sore.

Lifestyle tips

• Quit smoking and avoid second-hand smoke
• Limit alcohol and caffeine, as they can worsen acid reflux
• Elevate the head of your bed if you have night-time reflux
• Avoid eating within 2–3 hours before bed

Diet and exercise

Eat soft, bland foods until the pain goes away. Avoid spicy, acidic, or rough foods. Gentle exercise like walking is fine if you feel up to it, but rest if you have a fever or feel very tired.

Mental health and emotional wellbeing

Painful swallowing can be stressful and affect your enjoyment of meals. It may make you feel anxious about eating or drinking. Remember that this is temporary. Talk to your doctor if the stress feels overwhelming.

Prevention

You cannot always prevent painful swallowing, but you can reduce your risk by practicing good hand hygiene to avoid infections, not smoking, and managing acid reflux if you have it.

Vaccines

Some infections that cause painful swallowing can be prevented with vaccines, such as the flu vaccine and the COVID-19 vaccine. Ask your doctor about which vaccines are right for you.

Screening programmes

There is no routine screening for painful swallowing. See your doctor if you have ongoing or unexplained symptoms.

Complications

If left untreated

• Dehydration from not drinking enough
• Weight loss from not eating enough
• An abscess in the throat or tonsils (peritonsillar abscess)
• Spread of infection to the neck or chest

Long-term outlook

For most people, painful swallowing goes away on its own or with simple treatment. Even when it is caused by a more serious condition, getting the right care leads to improvement. With medical help, the outlook is very good.
