An anal fissure is a tear in the lining of your anus, or the lower part of your rectum, where stool passes out of your body. If you have an anal fissure, you may have pain during bowel movements or bright red blood on your stool or on the toilet paper after a bowel movement.

Anal Fissure Treatment at Rush

At Rush, a gastroenterologist can help you find relief from the pain of your anal fissure with a personalized treatment plan. This may involve one or more of the following:

  • Lifestyle changes, such as eating more high-fiber foods and drinking more fluids, to ease your pain and prevent future anal fissures
  • Medications that can relax your anal sphincter muscles that open and close to let stool pass
  • Botox (botulinum toxin) injections, which temporarily paralyze your anal sphincter muscles to reduce muscle tension and spasms that can prevent your anal fissure from healing
  • Lateral internal sphincterotomy, a simple surgery that can reduce pressure on the anal sphincter so your anal fissure can heal
