Varicose veins are enlarged “rope-like” veins — blood vessels — that are swollen and raised above the surface of the skin. They can be flesh-coloured, dark purple, or blue, and often look like a cluster of grapes. They are commonly found on the back of the calves or the inside of the legs. However, they can form anywhere on the legs, from groin to ankle. Spider veins are similar to varicose veins, but they are smaller and closer to the surface of the skin. They are often red or blue, and look like tree branches or spider webs. They can occur anywhere on the legs, and can cover either a very small or very large area of skin. They don’t bulge like varicose veins, but are often more noticeable.
