An anal fissure is a tear in the lining of the lower rectum anus. It can itch and cause pain. You may notice bright red blood on toilet paper after you wipe. A fissure may form if you are constipated and try to pass a large, hard stool or if you do not relax your anal muscles during a bowel movement. Most anal fissures heal with home treatment after a few days or weeks. If you have an anal fissure that takes more time to heal, your doctor may prescribe medicine.
About Anal Fissures | Memorial Sloan Kettering Cancer Center
An anal fissure can occur when someone passes a large or hard stool poop , which stretches the lining of the anus until it tears. It also can happen when frequent diarrhea irritates the lining. You may also see blood on the stool, baby wipes, or toilet tissue. In infants, anal fissures are very common and tend to heal completely with basic care, including soaks and ointment. In older kids and teens, the cuts can take several weeks or longer to heal and sometimes tear open again.
