Anal fissures are caused by trauma to the anus and anal canal. The cause of the trauma usually is a bowel movement, and many people can remember the exact bowel movement during which their pain began. The fissure may be caused by a hard stool or repeated episodes of diarrhea.
An anal fissure (fissure-in-ano) is a small, oval shaped tear in skin that lines the opening of the anus. Fissures typically cause severe pain and bleeding with bowel movements. Fissures are quite common in the general population, but are often confused with other causes of pain and bleeding, such as hemorrhoids.he typical symptoms of an anal fissure include severe pain during, and especially after, a bowel movement, lasting from several minutes to a few hours. Patients may also notice bright red blood from the anus that can be seen on the toilet paper or on the stool.
