If my legs ache or fatigue with walking, what could it mean?

Whilst venous insufficiency (and varicose veins) may result in aching, particularly when standing, leg discomfort from walking can be the sign of an arterial problem, such as obstruction. Dr. Attaran performs a comprehensive evaluation of circulation. Arterial and venous disease can be diagnosed by ultrasound imaging, in addition to a number of other modalities available at Yale University.
