The basic facts about varicose or spider veins

Your calf muscles help push blood toward the heart through veins and capillaries. Inside these vessels are little trapdoor-like valves that help prevent blood from flowing backward and collecting in the legs. With varicose veins these valves don't work properly: Blood pools, causing veins to bulge, and the resulting pressure permanently dilates the vein. Spider veins are like varicose veins but smaller. They begin as tiny capillaries and appear as blue or red squiggles.

What to look for if you're concerned about varicose or spider veins

Family history If relatives have varicose veins, your odds are higher.

Dull aching Pressure from pooled blood can cause a bothersome throbbing feeling that runs through your legs.

Thick, ropelike or twisted veins Varicose veins can protrude from the skin. Spider veins are tiny, flat weblike lines.

Simple solutions for your sexy legs

Maintain a healthy weight. Extra pounds put additional pressure on leg veins, which can weaken vessel walls.

Avoid crossing your legs. It slows blood circulation and also increases pressure inside the veins in your legs.

Rotate your ankles and stretch your legs. Do so periodically if you stand or sit a long time. If possible, take a quick walk. The movements boost blood flow and keep veins healthy.
