Overview
An anal fissure is a small tear in the lining of the anus, usually caused by passing hard or large stools. It causes sharp pain during and after passing motions, along with a little bright-red bleeding. Though very painful, fissures are not dangerous and most heal within a few weeks with a high-fibre diet, plenty of water and soothing measures. Long-standing fissures may need creams or a minor procedure.
Symptoms
- Sharp, burning pain while passing stools
- Pain that can last for hours afterwards
- Bright-red blood on the stool or toilet paper
- A visible small tear or skin tag near the anus
- Spasm and tightness of the back passage
When to see a doctor
See a doctor if pain or bleeding lasts more than a couple of weeks, is severe, or keeps returning.
Causes
Hard, large or frequent stools, constipation, straining, and sometimes diarrhea or childbirth.
