 ==Overview==
-An '''anal fissure''' is an unnatural crack or tear in the [[anus]] skin. As a fissure, these tiny tears may show as bright red rectal bleeding and cause severe periodic pain after defecation.<ref name="new">Gott M.D., Peter H. (March 5, 1998) [[The Fresno Bee]] ''New thearpy coming for anal fissures.'' Section:Life; Page E2</ref> The tear usually extends from the anal opening and located posteriorly in the midline. This location is probably because of the relatively unsupported nature of the anal wall in that location.
