Poor circulation in legs can occur when blood flow through the veins or arteries is reduced or impaired. Symptoms may include leg swelling, heaviness, aching, numbness, tingling, or changes in skin appearance. In some cases, poor circulation may be associated with an underlying vein disease that affects how blood returns from the legs to the heart. At USA Vein Clinics, patients experiencing persistent leg symptoms can discuss their concerns with qualified vein care professionals. https://www.usaveinclinics.com/vein-disease/poor-circulation/
