How Do You Know if You Have Hemorrhoids… or Something Serious?

2. What Is a Hemorrhoid, Exactly?

Hemorrhoids are veins in the wall in your rectum and anus that have become twisted, swollen, and inflamed. They can form either internally or externally, and the resulting lumps can cause pain and bleeding.

If you have a hemorrhoid inside your anus, above the junction of your rectum and anus, you have an internal hemorrhoid. If your hemorrhoids are below this junction and under the skin around the anus, they are considered to be external. Both types of hemorrhoids may remain in your anus or protrude outside it.
