 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 two types of hemorrhoids:
External 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
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. Sometimes internal hemorrhoids may be pushed out through the anus from straining, which can be quite painful. These are called prolapsed hemorrhoids.
