Symptoms and signs of a sore throat include:
- swollen tonsils (two small glands found at the back of your throat, behind the tongue)
- enlarged and tender glands in your neck
- a painful, tender feeling at the back of your throat
- discomfort when swallowing
If you have a sore throat, you may also experience other symptoms associated with common infectious conditions, such as:
- a high temperature (fever) of 38C (100.4F) or over
- aching muscles
- a headache
- tiredness
- a cough
- a runny nose
These other symptoms will depend on what infection is causing your sore throat.
When to visit your GP
If you have a sore throat, make an appointment to see your GP if:
- you have a persistent high temperature above 38C (100.4F) which is not reduced by medication
- your symptoms do not improve after two weeks
- you have frequent sore throats that do not respond to painkillers, such as paracetamol, ibuprofen or aspirin
It is important to investigate the cause of your temperature because it may be the result of a more serious condition, such as:
- epiglottitis: inflammation (swelling and redness) of the epiglottis (the flap of tissue at the back of the throat, underneath the tongue) which, if left untreated, can cause breathing difficulties
- quinsy: an abscess (a painful collection of pus) that develops between the back of the tonsil and the wall of the throat
Blood tests may be carried out if your GP suspects you have a type of viral infection called glandular fever (also known as infectious mononucleosis).
At-risk groups
While most sore throats can be treated at home, some people are more at risk than others of developing complications from a sore throat and may need additional treatment.
See your GP at the first sign of infection if you:
- have HIV and AIDS (a virus that attacks your immune system, the body’s defence system)
- have leukaemia (cancer of the bone marrow)
- have asplenia (your spleen, an organ behind your stomach, does not work properly or has been removed)
- have aplastic anaemia (when your bone marrow does not produce enough blood cells)
- are receiving chemotherapy
- are taking an immunosuppressant medicine (medicine that stops your immune system working), for example because you have had an organ transplant
- are taking an antithyroid medication (medication to stop your thyroid gland producing too many hormones), such as carbimazole
- are taking a disease-modifying anti-rheumatic drug (DMARD), for example to treat arthritis (a common condition that causes inflammation in the joints and bones)

Bone marrow
Bone marrow is the soft, spongy tissue in the centre of bones that produces blood cells.
Epiglottis
The epiglottis is a flap of tissue located towards the back of the throat. It sits underneath the tongue.
Hormones
Hormones are groups of powerful chemicals that are produced by the body and have a wide range of effects.
Inflammation
Inflammation is the body's response to infection, irritation or injury, which causes redness, swelling, pain and sometimes a feeling of heat in the affected area.
Immune system
The immune system is the body's defence system, which helps protect it from disease, bacteria and viruses.
Tonsils
Two small glands found at the back of your throat, behind the tongue.
