Hemorrhoids also called piles, are swollen veins in the anus and lower rectum. Hemorrhoids are similar to varicose veins. Hemorrhoids can develop inside the rectum, called internal hemorrhoids.

Hemorrhoids are very common. They result from increased pressure on the anus. This can occur during pregnancy or childbirth, and due to constipation. The pressure causes the normal anal veins and tissue to swell. A hemorrhoidectomy is a surgical procedure to remove hemorrhoids.

Hemorrhoid excision surgery can be quite painful, so you'll probably need to take medication afterward. You can discuss the various options with your doctor. The options may include a prescription pain reliever or an over-the-counter variety.
