Anal and perianal (or anorectal) abscesses

Overview

An anal, anorectal or perianal abscess is a bacterial infection in the area around the anus. It is particularly painful during a bowel movement or when sitting, and patients can also suffer from fever and a general feeling of being unwell. Usually the pus has to be drained during a small operation.
