Things to know about anal fissures
What is an anal fissure (fissure-in-ano)?
An anal fissure (fissure-in-ano) is a small cut or tear in the skin or moist tissue (mucosa) lining the opening of the anus, mostly in the posterior (back) midline of the anus. Usually oval in shape, the tear causes severe pain and bleeding with bowel movements. Fissures are common in young infants but can affect people of any age. Often confused with other causes of pain and bleeding such as hemorrhoids.
