A friend (female, age 55, non-smoker) has been experiencing these symptoms in both legs: tingling, numbness, swelling. She has been to vein doctor. One vein that was larger than it should be (and therefore the valves don t close properly and blood has a harder time circulating), but not significantly. He suggested it might be a nerve issue, esp. since symptoms are in both legs. Do you agree that it may be nerve related?
