Leg Pain (claudication)
Claudication is a pain in the extremities caused by a lack of blood flow. This is often first noticed during exercise. Claudication is most common in smokers or people with long-standing hypertension and/or diabetes.
Peripheral Arteries
The peripheral arteries are blood vessels that carry blood to the arms and legs. Problems with these vessels can cause pain in the arms or legs, although leg pain is much more common. This pain is called claudication.
