Arteries bring oxygen-rich blood from your heart to the rest of your body. Veins return oxygen-poor blood back to your heart. Varicose veins are swollen veins that you can see through your skin. They often look blue, bulging, and twisted. Left untreated, varicose veins may worsen over time. Large varicose veins can cause aching and fatigue as well as skin changes like rashes, redness, and sores. As many as 40 million Americans, most of them women, have varicose veins.
Treatment for varicose veins may include self-care measures, compression stockings, and surgeries or procedures. Procedures to treat varicose veins are often done as an outpatient procedure, which means you usually go home on the same day.
