Sore throat - tonsillitis

Tonsillitis is inflammation (swelling) of the tonsils.

If your child often has a sore throat, trouble swallowing, and ear pain, she may have a problem with her tonsils. So, what causes tonsillitis? The tonsils are small, dimpled, golf ball-like nodes on either side of the back of your child's throat. They normally help to filter out bacteria and other germs to prevent infection in the body. If the tonsils become so overwhelmed with bacteria from strep throat or a viral infection, they can swell and become inflamed, causing tonsillitis. Your child's doctor will look in your child's mouth and throat for swollen tonsils. The tonsils will probably be red and may have white spots on them. The lymph nodes in your child's jaw and neck may be swollen and tender to the touch. The doctor may test your child's blood for infection. If bacteria are the cause, your child will probably need to take antibiotics, either in a shot or in pill form. If your child needs to take antibiotic pills, make sure she takes all of the medicine. To comfort your child, give her cold liquids and popsicles. Gargling with salt water can help. She can also take over-the-counter medicine like acetaminophen or ibuprofen for her pain and fever. Tonsillitis usually improves two or three days after treatment starts. The infection usually goes away too, but some people may need to take antibiotics for longer. If your child has a great many repeated infections, surgery may be recommended to remove her tonsils, but this is no longer a common reason to have the tonsils out.

The lymphatic system filters fluid from around cells. It is an important part of the immune system. When people refer to swollen glands in the neck, they are usually referring to swollen lymph nodes. Common areas where lymph nodes can be easily felt, especially if they are enlarged, are the groin, armpits (axilla), above the clavicle (supraclavicular), in the neck (cervical), and the back of the head just above hairline (occipital).

Structures of the throat include the esophagus, trachea, epiglottis and tonsils.

Strep throat is the most common bacterial cause of sore throat. Because strep throat can occasionally lead to rheumatic fever, antibiotics are given. Strep throat often includes a fever (greater than 101 degrees Fahrenheit or 38.3 degrees Centigrade), white draining patches on the throat, and swollen or tender lymph glands in the neck. Children may have headache and stomach pain.

Causes

The tonsils are lymph nodes in the back of the mouth and top of the throat. They help to filter out bacteria and other germs to prevent infection in the body.

A bacterial or viral infection can cause tonsillitis. Strep throat is a common cause.

The infection may also be seen in other parts of the throat. One such infection is called pharyngitis.

Tonsillitis is very common in children.

Symptoms

Common symptoms may be:

  • Difficulty swallowing
  • Ear pain
  • Fever and chills
  • Headache
  • Sore throat, which lasts longer than 48 hours and may be severe
  • Tenderness of the jaw and throat

Other problems or symptoms that may occur are:

  • Problems breathing, if the tonsils are very large
  • Problems eating or drinking

Exams and Tests

Your health care provider will look in the mouth and throat.

  • The tonsils may be red and may have white spots on them.
  • The lymph nodes in the jaw and neck may be swollen and tender to the touch.

A rapid strep test can be done in most providers' offices. However, this test may be normal, and you can still have strep. Your provider may send the throat swab to a laboratory for a strep culture. Test results can take a few days.

Treatment

Swollen tonsils that are not painful or do not cause other problems do not need to be treated. Your provider may not give you antibiotics. You may be asked to come back for a checkup later.

If tests show you do have strep, your provider will give you antibiotics. It is important to finish all of your antibiotics as directed, even if you feel better. If you do not take them all, the infection can return.

The following tips may help your throat feel better:

  • Drink cold liquids or suck on fruit-flavored frozen bars.
  • Drink fluids, and mostly warm (not hot), bland fluids.
  • Gargle with warm salt water.
  • Suck on lozenges (containing benzocaine or similar ingredients) to reduce pain (these should not be used in young children because of the choking risk).
  • Take over-the-counter (OTC) medicines, such as acetaminophen (Tylenol) or ibuprofen to reduce pain and fever. DO NOT give a child aspirin. Aspirin has been linked to Reye syndrome.

Some people who have repeated infections may need surgery to remove the tonsils (tonsillectomy).

Outlook (Prognosis)

Tonsillitis symptoms due to strep will often get better within 2 or 3 days after you start the antibiotics.

Children with strep throat should be kept home from school or day care until they have been on antibiotics for 24 hours. This helps reduce the spread of illness.

Possible Complications

Complications from strep throat may be severe. They may include:

  • Abscess in the area around the tonsils
  • Kidney disease caused by strep
  • Rheumatic fever and other heart problems

When to Contact a Medical Professional

Call your provider if there is:

  • Excess drooling in a young child
  • Fever, particularly 101°F (38.3°C) or higher
  • Pus in the back of the throat
  • Red rash that feels rough, and increased redness in the skin folds
  • Severe problems swallowing or breathing
  • Tender or swollen lymph glands in the neck

Swollen lymph node and tonsil on one side

Why is one side of my tonsil swollen?

A person may experience swelling on just one side of the throat if only one tonsil is infected. People can take antibiotics to treat severe bacterial tonsilitis infections. However, if they experience tonsillitis more than five times in a year, a doctor may recommend surgery to remove the tonsils.

Why is only one of my throat glands swollen?

Lymph nodes usually swell in the area near an infection. If you have strep throat, for example, the lymph nodes in your neck may swell. Sometimes only one lymph node will swell, causing a sore throat on one side. In rare cases, swollen lymph nodes may be a sign of a more severe problem, such cancer or HIV.

Should I be worried if one tonsil is swollen?

Even if there is no growth but one tonsil is significantly larger than the other (a condition called asymmetrically enlarged tonsil), you should have it examined by an ENT Specialist.

What does a swollen gland on one side of the neck mean?

Swollen glands are: often caused by common illnesses like colds, tonsillitis and ear or throat infections. sometimes caused by viral infections such as glandular fever. rarely caused by anything more serious, like cancer of the blood system (leukaemia) or lymph system (lymphoma)
