Varicose veins are swollen blood vessels that appear just under your skin’s surface in your lower body. When your vein walls are weak and your valves aren’t working right, blood backs up in your vein. This causes the blue and purple bulges you see on your legs, feet or ankles. Several treatment options can work, but varicose veins can return.
What are varicose veins?
Varicose veins are swollen, twisted blood vessels that bulge just under your skin’s surface. These blue or purple bulges usually appear in your legs, feet and ankles. They can be painful or itchy. Spider veins, which may surround varicose veins, are smaller red or purple lines that appear close to your skin’s surface.
Although they can be unsightly and uncomfortable, varicose veins aren’t dangerous for most people. In some cases, severe varicose veins can lead to serious health problems, such as blood clots. You can relieve most varicose vein symptoms at home or your healthcare provider can treat them with injections, laser therapy or surgery.
What is the difference between varicose veins and spider veins?
Varicose veins and spider veins are both types of venous disease, but they look different. Spider veins are smaller and thinner than varicose veins. They look like red or blue spider webs or branches of a tree, and they are close to the skin’s surface.
Spider veins aren’t usually painful. They can appear anywhere on your body, most often behind your knee, on your feet or on your face. Varicose veins usually appear on your feet and legs.
