Anal fissure, a tiny tear in the thin, moist tissue that lines the anus. It usually occurs when you pass hard or large stools during a bowel movement, and it results in pain and bleeding with bowel movements. If you notice the initial signs of the fissure, it is essential to get it treated to heal faster. For anal fissure, healing without surgery is unlikely. We advise patients to undergo surgery if the pain is not bearable by ointments or other measures.
