Long saphenous vein blocked on left leg. could this cause sciatica? pain back of both legs, hips and right side groin. worse right side

No.: Development of a clot of what was once called the long saphenous vein may cause discomfort, tenderness to touch, redness, or warmth over the length of the vein itself -- something called thrombophlebitis. This is a local issue, self-limited, and should not lead to discomfort in the other leg or the hips. If the clot extends near its junction with the deep veins, it may lead to a DVT.
