Jump to content. An anal fissure is a tear in the lining of the lower rectum anal canal that causes pain during bowel movements. Anal fissures don't lead to more serious problems. Most anal fissures heal with home treatment after a few days or weeks. These are called short-term acute anal fissures.
Haemorrhoids, also known as piles, are enlarged and swollen blood vessels which are in or around the lower rectum and the anus. Most of the time you are not aware of having haemorrhoids but in most cases you will feel a small lump which is just inside or outside the anus. Bleeding from a pile can be quite scary when first discovered but it is not serious. Haemorrhoids, anal tears and anal fissures can all result in bleeding from the anus, which can be quite alarming. All these conditions are relatively common and in most cases any bleeding is not a cause for alarm. However, any bleeding from the anus should always be investigated immediately as it may be a symptom of a more serious condition.

An anal fissure fissure-in-ano is a small, oval shaped tear in skin that lines the opening of the anus. Fissures typically cause severe pain and bleeding with bowel movements. Fissures are quite common in the general population, but are often confused with other causes of pain and bleeding, such as hemorrhoids. Anal fissures can occur at any age and have equal gender distribution. A small number of patients may actually have fissures in both the front and the back locations.
