What You Should Know About Peripheral Artery Disease
Peripheral arterial disease—also known as P.A.D.—is a common, yet serious, disease. It occurs when extra cholesterol and other fats circulating in the blood collect in the walls of the arteries that supply blood to your limbs. This buildup—called plaque— narrows your arteries, often reducing or blocking the flow of blood.
The typical signs and symptoms of this disease include leg cramping, pain in the legs and feet during sleep, unhealing sores or wounds on the feet, skin discoloration on the feet, poor nail growth, and a difference of temperature from one leg to the other. Sometimes, though, none of these symptoms are present.
