I have a vein in my left leg that hurts. It is becoming larger and protruding. This vain is on my left leg above my knee on the outside of my leg. Is there a major artery there?

Varicose veins do occur in this area and are usually due to malfunctioning valves in either the saphenous vein or anterior accessory saphenous vein.
