Piles are caused by increased pressure in the lower rectum. The blood vessels around the anus and in the rectum will stretch under pressure and may swell or bulge, forming piles. This may be due to: chronic constipation. Prolapsed hemorrhoids look like swollen red lumps or bumps outside your anus. Prolapsed hemorrhoids may have no other symptom than the protrusion, or they may cause pain or discomfort, itchiness, or burning.
