What is the definition or description of: varicose veins on legs?

Bulging Veins.: Varicose veins are bulging grape-like appearing veins which are most commonly seen on the legs. These are due to leaking(refluxing) valves usually in the saphenous system. Some causes include hereditary, pregnancy, trauma and aging. The gold standard of treatment is to have a venous reflux ultrasound to both diagnose and form a treatment plan. You should see a vein specialist.

Varicose veins: Varicose veins are enlarged (dilated) sections of veins which are located just under the surface of the skin - usually on the leg. They are often easy to see, as they look thick and knobbly. They may be less obvious if you are overweight, as they are hidden by fatty tissue under the skin. http://patient.info/health/varicose-veins-leaflet
