Does anyone know of a reason why my left leg would have significantly more visible veins than my right? Both legs have quite a few visible but the left leg has more in general and some on the inner thigh that aren't visible at all on the right let. There is no pain or anything else involved. It becomes more noticeable when I am in competition shape.
My only two ideas are that is has to do with the heart being on the left side of the body or perhaps my stride is off balanced enough that my left leg is in better shape.
