When Visible Veins May Be a Medical Concern
Although visible veins are usually harmless, there are certain situations where they may signal an underlying vein condition.
Varicose Veins
Varicose veins are enlarged, twisted veins that commonly appear in the legs. They occur when valves inside the veins weaken, allowing blood to pool instead of flowing properly back toward the heart. Symptoms may include aching, heaviness, swelling, or itching around the veins.
Chronic Venous Insufficiency
This condition occurs when the veins have difficulty sending blood from the limbs back to the heart. Over time, this can cause swelling, skin discoloration, or discomfort in the legs.
In these cases, the veins may appear bulging, twisted, or painful, which is different from simply being visible under the skin.
