Tonsillitis is when the tonsils at the back of your throat become swollen. It’s caused by an infection.
Symptoms of tonsillitis include red, swollen tonsils, a sore throat and difficulty swallowing.
You can ease tonsillitis with things like lozenges, throat sprays and painkillers. A GP may prescribe antibiotics if it's caused by bacteria.
