There are several types of hemorrhoids, with internal, external, mixed and thrombosed external hemorrhoids being the most common. Among them, internal hemorrhoids can be divided into four degrees: degree I is mainly bleeding; degree II has prolapse but can be retracted back by lifting the anus; degree III internal hemorrhoids have to be pressed back by hand; and degree IV internal hemorrhoids, which may not be pressed back and are always on the outside. Each type of hemorrhoid may behave differently. In addition to prolapse, hemorrhoids have symptoms such as bleeding, pain, itching, and anal dampness. One of these thrombosed external hemorrhoids is a very painful condition that must be differentiated from a perianal abscess. Having hemorrhoids is actually not terrible, and it is important to find a professional doctor for diagnosis, as each person’s hemorrhoids may be different, and the surgery or treatment will be different, so it is recommended that you find a professional doctor for individualized treatment.
