Anorectal Fistula
An anorectal fistula is a tube-like tract that forms a continuous opening between the anus and the skin around it. These fistulas often develop as a result of an untreated or incompletely treated anorectal abscess. They are difficult to treat with Chinese medicine alone due to their location and the potential for contamination with feces. Symptoms of an anorectal fistula include chronic discharge of material, pain, and itching.
