Veins have one-way valves which prevent blood from backing up into the legs when we stand or sit. When the valves become incompetent (or begin to have reflux), blood pools and causes an increase in pressure in the leg veins. This may contribute to varicose veins and causes symptoms of fatigue, heaviness, aching, burning, throbbing, itching, cramping, swelling and restlessness of the legs. Severe varicose veins can compromise the nutrition of the skin, leading to eczema, inflammation or even ulceration of the lower leg.
