A complication of tonsillitis in which pus collects behind the tonsils.


Quinsy, also known as a peritonsillar abscess, happens when an infection caused by bacteria spreads beyond the tonsils. Swollen tissues can block the airway.


Symptoms include a sore throat and earache on the affected side. People with quinsy may also have a headache and feel generally unwell. Symptoms can include a high fever too.


Antibiotics can treat an early infection. The pus might need to be drained with a needle or through a small cut. Tonsils might be removed.
