What are anal fissures?

Anal fissures are cracks or sores in the region of the anal sphincter. It’s similar to a chapped lip, which is a little crack or a fissure along the lip margin. If you have this kind of crack in the area of your anal sphincter, that is called an anal fissure. This is usually due to some minor irritation or inflammation and is not the same as a hemorrhoid.
