http://hemorroidesremede.fr/ | Hemorrhoids are enlarged veins within the anus and rectum. They resemble varicose veins that occur on the leg. When irritated, hemorrhoidal veins might itch, burn, or bleed and trigger unpleasant inflammation in the encompassing membranes. Hemorrhoids are often caused by straining throughout a bowel motion, heavy lifting, childbirth, severe coughing, and constant sitting.
