Anal fissures are tears in the moist mucosa that lines the anus. They result from frequent diarrhea, firm stools, and other bowel issues. While painful, anal fissures are often minor and heal with time. Ulcers can have similar qualities to anal fissures and also lead to mucus in stools. Both may result from underlying conditions that affect the mucous membrane of the large intestine.
