A sore throat is caused by inflammation of the mucous membranes in the throat.
It results in a burning sensation, pain and irritation in your throat and mouth. It can occur on its own or be one of the symptoms of an infection such as a cold, flu, strep throat, pharyngitis or covid. It can also be caused by an inflammatory reaction, an allergy, gastro-oesophageal reflux, or caused by pollution, smoking or excessively dry air, etc.
Its symptoms generally begin with a tingling, irritated sensation in your throat, followed by pain and difficulty swallowing (odynophagia). The mucous membranes lining your throat are inflamed, so you feel a burning sensation. You may also experience hoarseness and coughing, as well as swelling of your tonsils and/or glands under your jaw. You may also experience a slight fever.
A dry or even a productive cough with mucus may follow.
Most of the time, a sore throat is not serious - although you should keep an eye on it - and lasts 2 to 7 days.
We advise you to consult a doctor if you are in any doubt about the cause of your sore throat, if it persists or if it is associated with more worrying symptoms (fever, difficulty breathing, severe pain, severe fatigue, etc.).
What causes a sore throat?
Sore throats can have several causes. They frequently occur as part of seasonal infections such as the common cold, the flu, strep throat, pharyngitis, bronchitis, or COVID-19. But they can also be exacerbated by excessively dry air, smoking, pollution, allergies, or gastroesophageal reflux.
When the throat’s mucous membranes are irritated, swallowing can become uncomfortable and the throat may feel more sensitive, dry, or sore. If the pain becomes severe, is accompanied by difficulty breathing, a high fever, or significant fatigue, or lasts longer than a week, medical advice is recommended.
