No. The best analogy is to think of it like the tip of an iceberg showing above the water, but hiding a substantial presence below the surface that is not visible.
Varicose veins are only a small part of chronic superficial venous insufficiency that can be seen on the surface. In order for that to occur, blood must engorge veins just below the surface.
For some people, the dilated veins bulge at the skin surface. For others, the veins are simply under the skin and cannot be seen.
In our experience at The Vein Institute, patients who have varicose veins have one advantage in that they have a clear sign of the disease process, as opposed to those without bulging veins who sometimes wait years and see multiple doctors without a diagnosis for these relatively vague symptoms.
