Varicose veins are larger than spider veins. The word “varicose” comes from the latin word “varix,” which means twisted. Varicose veins are usually blue and tend to bulge. As they enlarge, they may even become twisted, tortuous, gnarled, or even cord-like. They can occur anywhere in your leg from your groin to your ankle. Any vein can become a varicose vein, but they most commonly occur in your legs and feet.
Many people with varicose veins do not experience discomfort. In some cases, as more and more blood flows backward in the abnormal vein, the vein can become leaky causing symptoms of leg swelling and leg aches. Occasionally burning and throbbing occurs in your muscles as blood pools or backs up in your legs. Symptomatic varicose veins usually require treatment.
