Tonsillitis normally goes after a few days. Treatment can ease the symptoms until the infection goes. See a doctor if symptoms are severe or persist.
What are tonsils and what is tonsillitis?
Tonsils are made of soft glandular tissue and are part of the immune system. You have two tonsils, one on either side at the back of the mouth. The picture shows large non-infected tonsils (no redness or pus).
Tonsillitis is an infection of the tonsils. A sore throat is the most common of all tonsillitis symptoms. In addition, you may also have a cough, fever, headache, feel sick, feel tired, find swallowing painful, and have swollen neck glands. The tonsils may swell and become red. Pus may appear as white spots on the tonsils. Symptoms typically get worse over 2-3 days and then gradually go, usually within a week.
Is tonsillitis contagious / infectious?
As with coughs, colds, flu, and other similar infections, there is a chance that you can pass on the infection. In particular, if you are in close contact with others.
What is the treatment for tonsillitis?
- Not treating is an option as many tonsil infections are mild and soon get better.
- Have plenty to drink. It is tempting not to drink very much if it is painful to swallow. You may become mildly dehydrated if you don't drink much, particularly if you also have a fever. Mild dehydration can make headaches and tiredness much worse.
- Paracetamol or ibuprofen ease pain, headache, and fever. To keep symptoms to a minimum it is best to take a dose at regular intervals as recommended on the packet of medication rather than now and then. For example, take paracetamol four times a day until symptoms ease. Although either paracetamol or ibuprofen will usually help, there is some evidence to suggest that ibuprofen may be more effective than paracetamol at easing symptoms in adults. Paracetamol is usually the preferred first-line option for children, but ibuprofen can be used as an alternative. Note: some people with certain conditions may not be able to take ibuprofen. So, always read the packet label.
- Other gargles, lozenges, and sprays that you can buy at pharmacies may help to soothe a sore throat. However, they do not shorten the illness.
Do I need an antibiotic?
Usually not. Most throat and tonsil infections are caused by viruses, although some are caused by bacteria. Without tests, it is usually not possible to tell if it is a viral or bacterial infection. Antibiotics kill bacteria, but do not kill viruses. However, even if a bacterium is the cause of a tonsil or throat infection, an antibiotic does not make much difference in most cases. Your immune system usually clears these infections within a few days whether caused by a virus or a bacterium. Also, antibiotics can sometimes cause side-effects such as diarrhoea, rash, and stomach upsets.
So, most doctors do not prescribe antibiotics for most cases of tonsillitis or sore throat.
An antibiotic may be advised in certain situations. For example, if the infection is severe, if it is not easing after a few days, or if your immune system is not working properly (for example, if you have had your spleen removed, if you are taking chemotherapy, etc).
Things to look out for
In nearly all cases, a tonsillitis or sore throat clears away without leaving any problems. However, occasionally a typical tonsillitis may progress to cause a complication. Also, a sore throat or tonsillitis is sometimes due to an unusual, but more serious, illness.
Therefore, for the sake of completeness, the sort of things to look out for include the following:
Sometimes the infection can spread from the tonsils to other nearby tissues. For example, to cause an ear infection, sinus infection or chest infection.
Infectious mononucleosis (glandular fever)
Infectious mononucleosis is caused by a virus (the Epstein-Barr virus). It tends to cause a severe bout of tonsillitis in addition to other symptoms. See separate leaflet called 'Glandular Fever' for more details.
Quinsy - also known as peritonsillar abscess
Quinsy is an uncommon condition where an abscess (a collection of pus) develops next to a tonsil due to a bacterial infection. It usually develops just on one side. It may follow a tonsillitis or develop without a preceding tonsillitis. The tonsil on the affected side may be swollen or look normal, but is pushed towards the midline by the abscess next to the tonsil. Quinsy is very painful and can make you feel very unwell. It is treated with antibiotics, but also the pus often needs to be drained with a small operation.
Non-infective causes of a painful or swollen tonsil
These are rare. For example, cancer of the tonsil is rare, but pain can be the first symptom.
The 'take home' message is ... see a doctor if symptoms of a sore throat are severe, unusual, or if they do not ease within 3-4 days. In particular, seek urgent medical attention if you develop: difficulty in breathing; difficulty swallowing saliva; difficulty opening your mouth; severe pain; a persistent high temperature; a severe illness, especially with symptoms are mainly on one side of the throat.
What about having my tonsils taken out?
If you have recurring tonsillitis you may wonder about having your tonsils removed. Guidelines suggest it may be an option to have your tonsils removed (tonsillectomy) if you:
- Have had seven or more episodes of tonsillitis in the preceding year, or
- Five or more such episodes in each of the preceding two years, or
- Three or more such episodes in each of the preceding three years.
- The bouts of tonsillitis affect normal functioning. For example, they are severe enough to make you need time off from work or from school.
The adenoids may also be removed at the same time. Although full-blown episodes of tonsillitis are prevented after tonsillectomy, other throat infections are not prevented. However, there is a good chance that the overall number and severity of throat infections will be reduced. Also, the risk of developing quinsy is reduced. Many people say they generally feel better in themselves after having their tonsils removed if they previously had frequent episodes of tonsillitis.
Tonsillectomy is usually a straightforward minor operation. But note, as with all operations, there is a risk. For example, there is a small risk of life-threatening severe bleeding from the throat during and just after the operation.
