How dangerous is quinsy?

Quinsy, or peritonsillar abscess, can be quite dangerous if left untreated, as it may lead to serious complications, including airway obstruction, sepsis, and the spread of infection to surrounding tissues. Symptoms typically include severe sore throat, difficulty swallowing, and swelling. Prompt medical treatment, often involving drainage of the abscess and antibiotics, is crucial to prevent complications. While it can be serious, most cases are successfully managed with timely intervention.
