An anal fistula is defined as an infected tunnel that develops between the skin and the muscular opening at the end of the anus.

Hemorrhoids are enlarged, bulging veins within and around the anal canal. The two groups of hemorrhoids are external and internal hemorrhoids which are differentiated by their location. The internal hemorrhoid problems can be classified as per the severity, ranging from grade 1 without prolapse to grade 4 in which hemorrhoid remains prolapsed outside of the anus.

Hemorrhoids are swollen veins within and around the anal canal. The veins around the anus tend to stretch under the increased pressure and may be swollen. If you have experienced an acute anal pain with per rectal bleeding related to the bowel movements, it is highly recommended to seek for an urgent medical attention. This could be the signs and symptoms of ruptured hemorrhoids.
