Why Does My Throat Hurt When I Swallow? Causes and Treatment

Painful swallowing is a common complaint. It can occur with a viral infection of the throat, tonsillitis, acid reflux, dryness or irritation, but sometimes it indicates a problem with the tonsils, throat, esophagus or other tissues.

The medical term for painful swallowing is odynophagia. A sore throat is a broader symptom that may cause dryness, irritation or pain in the throat, while odynophagia specifically refers to pain caused by swallowing. The symptoms can vary depending on the underlying cause.

What Causes Pain When Swallowing?

1. Viral Throat Infection

A viral infection is one of the most common causes of throat pain. Colds, flu and other viral infections can cause a sore throat and pain while swallowing. Other symptoms may include a runny or stuffy nose, cough, mild fever, body aches, tiredness or hoarseness.

2. Tonsillitis

The tonsils are two small pieces of tissue at the back of the throat that help the immune system fight infection. Inflammation or infection of the tonsils is called tonsillitis.

It can cause severe sore throat pain when swallowing. The tonsils may look swollen and red, and white spots or patches may be visible. You may also have fever, tender or swollen glands in the neck, bad breath and a general feeling of being unwell.

3. Bacterial Throat Infection

A bacterial infection of the throat can also cause sore throat pain. This type of infection may cause sudden throat pain, especially when swallowing. Other symptoms may include high fever, tender or swollen glands, red or swollen tonsils, and the absence of a typical cough.

During medical assessment, if a bacterial infection is suspected or confirmed, an ENT specialist may prescribe an appropriate antibiotic. You should not take antibiotics without medical advice.

4. Acid Reflux

Acid reflux occurs when stomach contents flow back into the food pipe and sometimes reach the throat. It can cause throat irritation or burning, particularly after meals. Other symptoms may include discomfort when swallowing, a lump-like feeling in the throat, frequent throat clearing, hoarseness and a sour or bitter taste.

Reflux-related throat symptoms can occur even without typical heartburn and are sometimes referred to as laryngopharyngeal reflux or “silent reflux”.

5. Dryness and Irritation

Speaking for long periods, sleeping with your mouth open or regularly breathing through your mouth can contribute to throat dryness and irritation. If you breathe through your mouth because of a stuffy nose, you may wake up with a dry or sore throat.

Simple measures such as saltwater gargles, warm fluids with honey, a humidifier, and lozenges or hard candy may provide temporary relief. If the symptoms continue for more than a week or keep returning, consult an ENT specialist.

6. Throat Injury

If you feel that something is stuck in your throat or your throat has been irritated or scratched while swallowing hot food or drinks, it is important to seek medical advice, particularly if the symptoms are severe or persistent.

Difficulty breathing, inability to swallow saliva, significant bleeding or rapidly increasing swelling are critical warning signs and require urgent medical attention.

7. Post-Nasal Drip

If mucus regularly runs down the back of the throat, it can cause irritation and soreness. Post-nasal drip can occur due to allergies, sinus problems, colds or infections of the nose.

Drinking enough water and using saline nasal rinses may help reduce irritation. If the problem continues or keeps returning, consult your doctor for further evaluation and treatment. Difficulty breathing or bloody mucus requires prompt medical attention.

8. Ulcers in the Mouth or Throat

Small ulcers or sores in the mouth or throat can cause pain when swallowing. These sores can be due to irritation, infection or other causes.

Most common mouth ulcers, such as canker sores, usually heal on their own within one to two weeks. If an ulcer lasts longer than three weeks, keeps returning, bleeds or does not heal properly, it should be examined by a doctor or dentist.

For temporary relief, you can use a saltwater or baking soda rinse by gently swishing and spitting it out. Eating soft, cool foods such as yogurt and avoiding spicy, hot, acidic or salty foods and drinks may also help. You can gently hold an ice chip against the sore for temporary relief from sharp or burning pain.

How Does an ENT Diagnose Painful Swallowing?

An ENT specialist will first ask about the duration and nature of the pain, whether it occurs when swallowing food or liquids, and whether you have other symptoms such as fever, cough, hoarseness, nasal blockage or reflux.

The doctor will examine your mouth, throat, tonsils and neck. Depending on the findings, tests may be recommended to identify the underlying cause and decide on the appropriate treatment.

At Dr Vijay ENT Hospital, our ENT specialists can assess your symptoms and recommend appropriate treatment based on the cause.

When Should You Consult an ENT Specialist?

Most sore throats are not serious and should go away on their own after a few days. However, if your symptoms persist, keep coming back or become worse, you should consult an ENT specialist.

You should also consult a doctor if you experience any of the following symptoms:

  • Difficulty breathing
  • Severe difficulty swallowing
  • Unable to swallow saliva, fluids or food
  • Drooling because you cannot swallow
  • Severe swelling of the throat or neck
  • High-grade fever
  • Blood in saliva or phlegm
  • Recurrent sore throat
  • A persistent lump or thickened area in the throat
  • Persistent hoarseness
  • Unexplained weight loss
  • Throat pain that persists for several weeks

Does Painful Swallowing Always Mean a Throat Infection?

No, a sore throat is not always caused by a throat infection.

A sore throat can occur because of acid reflux, dryness, allergies, post-nasal drip, irritation, injury or other non-infectious causes. That is why it is important not to assume that the underlying cause is an infection, especially if the symptoms keep coming back. Repeatedly treating throat symptoms with antibiotics when they are not needed may delay the correct diagnosis.

An ENT specialist can help identify the underlying cause of persistent or recurrent throat discomfort.

When Throat Symptoms Need Urgent Attention

Severe or rapidly increasing swelling of the throat, tongue or mouth, inability to swallow saliva or fluids, inability to open the mouth fully, or noisy breathing such as stridor require immediate medical attention.

Finding the underlying cause is important, especially when throat pain persists or keeps returning. Proper diagnosis helps ensure that the underlying condition is treated appropriately and that persistent or serious problems are not overlooked.
