An anal fissure is a tear in the lining of the anal canal or anus that may be caused by trauma to the anus and anal canal by chronic constipation, straining to have a bowel movement, prolonged diarrhea, anal sex and anal stretching or insertion of foreign objects into the anus. Anal fissures can be painful and may bleed.
