Hemorrhoids are a very common medical problem. They are small veins around the rectum and anus that have become varicose - dilated and swollen. Hemorrhoids may become inflamed, develop small blood clots or even cause minor bleeding.
There are 2 types of hemorrhoids:
External hemorrhoids are round, purple and feel like "soft swellings." They develop under the skin just outside the opening of the anus. They can itch and be painful (especially during a bowel movement) and are often tender to the touch.
Internal hemorrhoids are found further inside the rectum. Typically, they're not painful; you may not even know they're there unless they start to bleed. However, internal hemorrhoids can be quite painful - in particular when straining pushes them out through the anus.
