A hemorrhoid is a dilated (swollen) rectal vein. While humans have blood vessels in every part of our bodies, a hemorrhoid is located primarily in the anorectal region. You are usually not even aware of veins in that area until they become inflamed or enlarged. That’s when these veins can cause pain, discomfort, and, in some cases, bleeding. Hemorrhoids, in general, are a benign condition, but they can be annoying. You may experience burning, itching, and, in some cases, bleeding. If you have bleeding from your rectum, consult your physician.
