Anal fissures may present with rectal pain described as burning, cutting, or tearing that occurs with bowel movements. Spasm of the anus is very suggestive for an anal fissure. A history of constipation or passage of hard stools may be present. Typically, bright-red blood appears on the surface of stools, but blood usually is not mixed into stool and is present only in a small amount. Occasionally, blood is found on toilet paper after wiping. The patient may report no bleeding.
