The condition is called chronic venous insufficiency (CVI).ĬVI can occur in both superficial veins close to your skin and deep leg veins embedded inside your leg. If the valves in your veins aren’t opening and closing as they should, the blood can flow backward. As a result, your blood may pool in the veins, putting pressure on the vein walls. Blood flow decreases if a valve doesn’t open all the way.

If the valves become damaged, they no longer work effectively. Veins have one-way valves that open and close to move blood toward your heart. They carry blood back to your heart after your arteries carry it out.

Your veins are an important part of your body’s circulatory system. Problems in your veins, especially your leg veins, occur more often in adults over 50 years old, and more often in women than in men.

After you’ve been on your feet for a while, do your legs start aching and even burning? Are your feet and ankles swollen? These are some of the signs you may be developing vein problems.
