When veins within the rectum above the anus, are swollen, they are called internal hemorrhoids. You can have an internal hemorrhoid and experience no symptoms, although occasionally, you might experience a small amount of bleeding with internal hemorrhoids, resulting in bright red blood on the stool or on toilet paper.
Typically, internally hemorrhoids cause no pain. However, in rare occurrences, enlarged veins may stick out from the anus. These "protruding hemorrhoids" may itch or cause some pain and discomfort.
