Complications of anal fissure can include:

  • Failure to heal. An anal fissure that fails to heal within six weeks is considered chronic and may need further treatment.
  • Recurrence. Once you've experienced an anal fissure, you are prone to having another one.
  • A tear that extends to surrounding muscles. An anal fissure may extend into the ring of muscle that holds your anus closed (internal anal sphincter), making it more difficult for your anal fissure to heal. An unhealed fissure can trigger a cycle of discomfort that may require medications or surgery to reduce the pain and to repair or remove the fissure
