twisted, enlarged veins near the surface of the skin. They are most common in
the legs and ankles. They usually aren't serious, but they can sometimes lead
to other problems.

caused by weakened valves and veins in your legs. Normally, one-way valves in
your veins keep blood flowing from your legs up toward your heart. When these
valves do not work as they should, blood collects in your legs, and pressure
builds up. The veins become weak, large, and twisted.

look at your legs and feet. Varicose veins are easy to see, especially when you
stand up. Your doctor will check your legs for tender areas, swelling, skin
color changes, sores, and other signs of skin breakdown.

have signs of a deep vein problem.
