What is an Anal Fissure?
An anal fissure is a tear in the anoderm, which is a unique skin area near the opening of the anus. Often, an anal fissure is caused by passing a hard stool. Sometimes, an anal fissure can also arise after childbirth.
This condition is painful. It results in painful bowel movements, which might be described as ‘passing razor blades’. Bright red blood is often visible on the toilet paper.
When an anal fissure causes this pain, there can be a resulting spasm of the anal sphincter muscle. This compounds the pain and can make it more difficult for the fissure to heal.
