An anal fissure is a small tear or crack in the lining of the anus. It may occur when passing large or hard stools, straining during childbirth, or experiencing bouts of diarrhea.
An anal fissure can cause sharp pain and bleeding during and after bowel movements. It may also cause itching and burning in the anal area.
An anal fissure is usually a minor condition that goes away within six weeks. Home treatments can help ease pain and promote healing.
An anal fissure may cause one or more of the following symptoms:
a visible tear in the skin around the anus
a skin tag, or small lump of skin, next to the tear
sharp pain in the anal area during bowel movements
streaks of blood on stools or on tissue paper after wiping
burning or itching in the anal area
How is an anal fissure diagnosed?
A doctor can usually diagnose an anal fissure simply by examining the area around the anus. However, they may want to perform a digital rectal exam to confirm the diagnosis.
