An anal fissure is a small tear in the lining of the anal canal. Common in infants ages 6 to 24 months, anal fissures are less likely to develop in older children. Adults may develop anal fissures as a result of passing hard or large stools during bowel movements.

Anal fissures may cause pain and bleeding. More than 90 percent heal on their own, and you can use topical creams or suppositories to provide relief as they heal. Anal fissures that fail to heal may become chronic and cause considerable discomfort.

If you develop an anal fissure that fails to heal, surgery may relieve your discomfort.
