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.
Leg Veins. Deep leg veins (the light blue veins in the picture) include the iliac, femoral, popliteal, and tibial veins. Superficial leg veins (the dark blue veins) include the greater and lesser saphenous veins. In deep vein thrombosis, a blood clot (thrombus) forms in a deep vein, usually in the legs. Clots also can form in superficial veins, which are closer to the skin.
