A peritonsillar abscess is a bacterial infection that is usually a result of a complication arises due to an untreated strep throat or tonsillitis. It mostly involves a pus-filled pocket that forms near one of your tonsils, resulting into symptoms like enlarged ,tender lymph glands in neck, painful swallowing, fever and chills, spasm in the muscles of the jaw (trismus) and neck (torticollis), ear pain on the same side as the abscess, a muffled voice – often described as a “hot potato” voice, and difficulty swallowing saliva. An incision is made in the abscess using a scalpel to drain the collected pus. An antibiotic, most commonly Penicillin is administered during this procedure. General anaesthesia may be required for young children.
