Many anal as well as rectal area lesions can cause itching as well as bleeding, especially hemorrhoids, perianal abscesses, and perianal eczema. One of the most common causes is hemorrhoids. Hemorrhoids are caused by varicose veins around the anus, especially thrombosed external hemorrhoids, which cause visible clusters of veins or blood clots around the anus and can cause significant itching and bleeding from fecal irritation during bowel movements. Due to the perianal eczema triggered by the phenomenon, perianal eczema is mainly caused by the environment around the anus for a long time moisture, as well as their own hormone imbalance, will form pimples on the skin around the anus as well as ulceration, which will cause itching, pain and bleeding around the anus. In addition, acute inflammatory lesions occurring at the end of the rectum are prone to form perianal abscesses around the anus due to pus collection, and cause itching and blood in the stool.
