An anal fissure is a small tear or split in the moist tissue that covers the anus. Anal fissures typically occur with the passing of large, hard stools. Most anal fissures heal with home treatment after a few days or weeks. These are called short-term (acute) anal fissures. If you have an anal fissure that hasn't healed after 8 to 12 weeks, it is considered a long-term (chronic) fissure. A chronic fissure may need medical treatment.
