If you find your anus spot swollen and painful during bowel release, beware that you might be suffering from piles. Piles, hemorrhoids or also known as hemroids, are inflamed rectal veins that are inside the rectum or outside the anus. It can be quite distressing to see spots of bright red blood on a square of toilet paper and you may be wondering why it’s happening to you and how to go about treating hemorrhoids.
