The most common causes of perianal lesions include hemorrhoids as well as perianal abscesses and rectal polyps. Hemorrhoids around the anus can lead to painful finger examinations, the formation of blood clots or venous blood clots around the anus, and even painful bowel movements and blood in the stool. Most perianal abscesses form a fistula around the anus that connects the skin around the anus to the end of the rectum, which can cause increased pain when the anus is pressed. In addition, the end of the rectum can be compressed during anal fingering. If a rectal polyp occurs at the same time, the pain may be unbearable due to the pressure during the finger examination.
