An anal fissure is a small tear at the anal opening. It can cause sharp pain during a bowel movement, burning afterwards and a small amount of bright red blood.
Common causes
Hard stools, constipation or frequent diarrhoea may contribute. Pain or bleeding can have other causes, so a professional assessment is important.

Treatment may include steps to soften stools, prescribed creams, injections or a procedure for selected persistent fissures. A clinician can explain what is suitable for you.
