Overview
Tonsillitis is inflammation of the tonsils, the two soft glands at the back of the throat, usually from a viral or bacterial infection. It causes a sore throat, painful swallowing and often fever, and is especially common in children. Most cases settle within a week with rest and fluids; bacterial tonsillitis may need antibiotics. Children who get repeated severe attacks are sometimes advised to have their tonsils removed.
Symptoms
- Sore throat and painful swallowing
- Red, swollen tonsils, sometimes with white or yellow patches
- Fever
- Swollen, tender glands in the neck
- Bad breath and a muffled voice
When to see a doctor
See a doctor if the sore throat is severe, lasts more than four days, or comes with high fever and difficulty swallowing.
Emergency — call 108 or go to the nearest hospital
- Difficulty breathing or swallowing saliva, drooling, or severe one-sided swelling of the throat — go to a hospital immediately
Causes
Viruses (most common) and bacteria such as streptococcus, spread through coughs, sneezes and close contact.
