Leg Pain. Varicose vein disease is a common and often underappreciated cause of leg pain. Varicose veins may be overlooked as a cause of leg pain because not all varicose veins bulge on the surface; some are invisible and located deeper in the leg. Leaking varicose veins cause blood to pool and waste products to accumulate in the leg.
There are three types of veins in the legs: 1  Superficial veins, which are the ones just below the skin surface. You can often see or feel the larger superficial veins. The superficial leg veins are the ones that may develop into varicose veins. 2  Deep leg veins, which pass through the muscles. You cannot see or feel these.
