  • What exactly is an anal fissure?
    MedlinePlusMay 2026

    An anal fissure is a small crack or tear in the lining of your anus, which is the opening at the end of your large intestine where stool leaves your body. It's a common problem that usually causes pain and sometimes bleeding.

  • Why do I have pain when I go to the bathroom?
    MedlinePlusMay 2026

    Anal fissures cause pain during bowel movements because the tear in the sensitive tissue gets stretched when stool passes through. The pain can be sharp and may last for a while after you go to the bathroom.

  • Can stress or diet make my fissure worse?
    MedlinePlusMay 2026

    Yes, diet and stress can make fissures worse. Hard or dry stools from a low-fiber diet can irritate the tear, and stress can tighten the muscles around your anus, increasing pain and slowing healing.

  • Will this condition ever get better on its own?
    MedlinePlusMay 2026

    Many anal fissures do heal on their own with time and self-care, especially if you keep your stools soft and avoid straining. However, some fissures need medical treatment to heal properly.
