If you have an anal fissure, you may have the following symptoms:a sharp, searing or burning pain in or around your anus. This pain can last for a couple of hours after a bowel movement and is severe; a streak of blood when using toilet paper or drops of blood in the toilet bowl; or a sentinel pile. This is a tag of skin that can develop on the edge of your anus below the fissure. A sentinel pile isn't a haemorrhoid. If you have these symptoms, see your doctor.
