What are varicose veins?
Varicose veins are enlarged, twisted, blue veins that are close to the surface of the skin. Because valves in them are damaged, they hold more blood at higher pressure than normal. That forces fluid into the surrounding tissue, making the affected leg swell and feel heavy, achy, tired, painful, and fatigued. Skin symptoms include itching, burning, dryness, redness, and ulceration. Sometimes varicose veins can be present without symptoms. Eventually the veins get worse and symptoms develop.
