Anal fissures: patterns and care

At a glance

An anal fissure is a small tear in the lining of the anus. People often describe it as a sharp, burning, or cutting pain during or after a bowel movement. It is one of the most common causes of anal pain.

This page covers what people commonly experience, what tends to help or make things worse, and when to seek care.

Common patterns people report

  • Sharp pain during bowel movements, sometimes described as “like passing glass”
  • Pain that continues for minutes to hours after a bowel movement
  • Small amounts of bright red blood on toilet paper
  • A visible small tear or cut
  • Muscle spasm that worsens pain after the initial tear
  • Fear of bowel movements leading to avoidance, which can worsen constipation

What tends to help

  • Fiber and hydration — softening stools to reduce strain. People commonly try psyllium husk, adequate water intake, and dietary changes.
  • Sitz baths — warm water soaks for 10 to 15 minutes, particularly after bowel movements. Many people find this soothing.
  • Not delaying bowel movements — responding promptly to the urge rather than holding.
  • Prescribed topical treatments — a doctor may prescribe ointments to help with healing and spasm.

What tends to make things worse

  • Constipation and straining
  • Hard stools
  • Diarrhea (which can irritate the area)
  • Prolonged sitting
  • Avoiding bowel movements out of fear of pain
  • Spicy foods (some people report this as a trigger)

Talking to your doctor

If you are considering seeing a doctor, it can help to note:

  • When symptoms started
  • How often pain occurs
  • Whether you have noticed bleeding
  • What you have already tried
  • Whether symptoms are getting better, stable, or worse

Many people feel embarrassed discussing these symptoms. Doctors see these conditions regularly and can help.

When to seek care

If you experience any of the following, seek urgent medical care:

  • Severe or worsening pain
  • Heavy bleeding
  • Fever
  • Black stools
  • Fainting or dizziness
  • Pus or unusual discharge
  • Inability to pass stool or gas
  • Unexplained weight loss
