An anal fissure is a small cut or tear in the lining of the anus. The crack in the skin causes severe pain and some bright red bleeding during and after bowel movements. At times, the fissure can be deep enough to expose the muscle tissue underneath. In most cases, the tear heals on its own within four to six weeks. Certain treatments can promote healing and help relieve discomfort, including stool softeners and topical pain relievers. Or your doctor may need to look for other underlying disorders that can cause anal fissures. An anal fissure most often occurs when passing large or hard stools.

Anal fissure: Causes, symptoms, and treatments
An anal fissure is a shallow ulceration or tear in the tissue along the anal canal. During bowel movements, irritation of the fissure can trigger a spasm in the anal sphincter, the muscle that surrounds the opening of the anus. Such spasms are often quite painful and may be accompanied by bleeding. This condition is more common among women. Anal fissures are typically caused when large, hard stools tear the lining of the anal canal as they pass. Trauma to the inner lining of the anus can cause a fissure.
