How do i know if i have a hemorrhoid, or anal fissure?

Have it evaluated: I suppose if you were a contortionist and had a mirror you might figure this out by looking. However, spotting a fissure would not rule out having a hemorrhoid internally that could be your main problem.Having you doc or a GI doc do a formal anoscopy (look at and up your anus) would sort this out. If you just have minor itching down there, local application of emollients like coco butter can help.
