Thank you for the query.
Most likely you do suffer from anal fissure
. Sphincter muscle is located under soft tissues and it is hard to tear it with the stool. So it is the mucosa what gets teared. And this wound hurts. It is also possible that you do have hemorrhoids which can also be very painful. Both diseases give fresh blood in stool
(not mixed with it).
To get rid of this symptoms you should: avoid constipations, increase fiber rich products and mineral water intake, ask your doctor for Nitroglycerine gel prescription (it relaxes the sphincter so the wound can get healed), have sitz baths with Quercus Cortex
. Such treated fissure should get healed in a week or so. If not, colonoscopy
should be performed.
Hope this will help.
