An anal fissure is a small tear in the lower rectum which can cause pain during bowel movements. While most anal fissures heal within a couple days or weeks, some can become chronic, which may need medical treatment. Chronic anal fissure is one that hasn’t healed after 8-12 weeks.

Anal fissures are common, and affect people of all age, regardless of health. Anal fissures are caused when there is injury to the anal canal. Injury can happen due to:

  • Strain of constipation
  • Passing a large or hard stool
  • Childbirth
  • Rectal exam
  • Anal intercourse
  • Foreign object

The symptoms of an anal fissure include:

  • Pain during and/or after bowel movements (pain can be quite severe)
  • Blood on the stool or toilet paper after a bowel movement
  • Itching or irritation

The Mayo Clinic states that the best way to prevent an anal fissure is by trying to prevent constipation. This can be done by eating high-fiber foods, drinking lots of fluids, and exercising regularly.

ClinSearch is currently enrolling people with anal fissures for a clinical study testing the safety and effectiveness of an investigational injectable medication. To find out more about the study and to see if you may qualify, call our office at (423) 308-3008 or visit our website at
