Varicose Veins - Topic Overview

Varicose veins are twisted, enlarged veinscamera.gif 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.

Varicose veins are 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.

Varicose veins often run in families. Aging also increases your risk.

Being overweight or pregnant or having a job where you must stand for long periods of time increases pressure on leg veins. This can lead to varicose veins.

Varicose veins look dark blue, swollen, and twisted under the skin. Some people do not have any symptoms. Mild symptoms may include:

  • Heaviness, burning, aching, tiredness, or pain in your legs. Symptoms may be worse after you stand or sit for long periods of time.
  • Swelling in your feet and ankles.
  • Itching over the vein.

More serious symptoms include:

  • Leg swelling.
  • Swelling and calf pain after you sit or stand for long periods of time.
  • Skin changes, such as:
    • Color changes.
    • Dry, thinned skin.
    • Inflammation.
    • Scaling.
  • Open sores, or you may bleed after a minor injury.

Varicose veins are common and usually aren't a sign of a serious problem. But in some cases, varicose veins can be a sign of a blockage in the deeper veins called deep vein thrombosis. If you have this problem, you may need treatment for it.

Your doctor will 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.

You might need further tests if you plan to have treatment or if you have signs of a deep vein problem.
