An acute anal fissure is essentially a tiny paper cut located in the skin of the anal canal, which is the short, muscular tube that connects the end of your bowel to the outside of your body. Because this area is filled with many nerves, even a very small tear can be quite painful.
This happens when the skin is stretched beyond its limit. It is considered 'acute' because it is a new, recent injury rather than a chronic or long-term problem that has been present for months.
Common Symptoms
- Sharp, stinging pain during or immediately after a bowel movement.
- A feeling of burning or throbbing that can last for several hours after using the bathroom.
- Small amounts of bright red blood on the toilet paper or on the surface of your stool.
- A visible tiny tear or crack in the skin around the anus.
