Tonsillitis - myDr.com.au

Tonsillitis is inflammation of your tonsils. The tonsils are glands found at both sides of the back of your throat.
Your tonsils are part of your immune system and help protect your body against infection.
Tonsillitis makes your tonsils swollen and sore. It is most common in children. Adults can get tonsillitis, but it is less common.
Symptoms of tonsillitis include:
You may notice that your tonsils look red and swollen.
Tonsillitis is usually caused by viruses, often the same viruses that cause colds and flu.
Glandular fever, usually caused by the Epstein-Barr virus, can cause severe tonsillitis, usually in teenagers.
Tonsillitis can also be caused by bacteria. The most common type of bacteria involved is streptococcus (sometimes called 'strep' throat).
Tonsillitis itself is not contagious, but the viruses and bacteria that cause tonsillitis can be spread to other people.
To avoid spreading infection, it's important to:
If your child has tonsillitis, they should stay at home until their fever has gone and they are able to swallow comfortably again. This will usually take 3 to 4 days.
If you think your child has tonsillitis for the first time, take them to their doctor. If your child has had tonsillitis before and they usually improve with care at home, you don't always need to see a doctor.
See your doctor if you are worried, or if you or your child has:
To diagnose tonsillitis, your doctor will ask about your symptoms and examine you. They will check for redness or spots on your tonsils and swollen lymph nodes. They might also check your temperature and examine your skin and abdomen.
For people at low risk of rheumatic fever, a throat swab is not usually recommended.
Your treatment will depend on the cause of your tonsillitis and how severe your symptoms are. Most people with tonsillitis can recover at home and will feel better in about a week.
Most people who have tonsillitis do not need antibiotics.
Your doctor may prescribe antibiotics if you develop complications of tonsillitis, or have a high risk of developing rheumatic fever.

Paracetamol can help reduce pain, fever or headache. It usually works well for people with tonsillitis.
If you have severe pain that isn't responding to paracetamol, your doctor may prescribe other medicines such as prednisolone.
General measures to help you or your child recover include:
If you or your child gets tonsillitis a lot, your doctor may recommend surgery to remove your tonsils. The operation is known as a tonsillectomy.
People who have a tonsillectomy need a general anaesthetic. Some people have the tonsillectomy as day surgery, others stay in hospital overnight.
A tonsillectomy is a very common surgery. However, all surgeries have some risks. You should discuss these with your doctor.
Talk to your doctor about whether a tonsillectomy is likely to help you or your child.
Sometimes tonsillitis is caused by a bacterial infection called Group A streptococcus. If left untreated, this kind of infection can cause complications, such as:
A middle ear infection is a common complication of tonsillitis.
An uncommon complication of tonsillitis is a peri-tonsillar or neck abscess (collection of pus). This can cause symptoms including:
There is no vaccine against tonsillitis. Having tonsillitis doesn't protect you from getting it again — you can have it more than once.
There are things you can do to help prevent spreading the viruses and bacteria that cause tonsillitis.
