External Hemorrhoids
External hemorrhoids occur as bulges or lumps around the anus. Because of the sensitive nerve fibers in this area, these enlarged veins are often painful, especially when sitting. They also may bleed and itch. Should blood pool in an external hemorrhoid, a blood clot referred to as a thrombosed hemorrhoid may develop and cause severe pain.
The less common of the two forms, external hemorrhoids are often incorrectly self-diagnosed because many people mistake internal hemorrhoids—or the skin tags they can produce—for external hemorrhoids. Always consult a physician to determine whether you have the internal or external type.
