Hello! Thank you for the query. Such anal skin rupture is called anal fissure. At the beginning it appears as acute fissure and if not treated property, becomes severe one. Such severe fissure is very hard to treat and usually surgery is necessary. However if you have not tried any treatment there is a possibility that it will go away. To do that you should: - avoid constipations and do not push hard on stool - increase fiber rich products and mineral water intake - have sitz baths with Quercus Cortex - wash your rectum after every stool - ask your doctor about Nitroglycerin gel and Xylocaine gel Such treated fissure should go away in a week or two. If not, surgical removal might be the only option. Hope this will help. Regards.
