Spider veins and smaller varicose veins can be treated by Dr. Tresley at our Chicago area practice. Dark leg veins can be an unsightly blemish. Often hereditary and more common in women than in men, leg veins are caused by weak vascular walls and poor circulation. Do you work long hours on your feet? This can also be a contributor to spider and varicose veins. For more information or to schedule a consultation, contact our office today.
