When an infection of the tonsils (known as tonsillitis) spreads and causes infection in the soft tissues, a peritonsillar abscess may result. An abscess is a collection of pus that forms near an area of infected skin or other soft tissue. You need to see a doctor about this condition. Sometimes it can be cured with medication, but often as not the tonsils need to be removed. For more information
