Peripheral artery disease can cause claudication, or pain that occurs in the legs usually when walking or exercising. Blood clots (deep vein thrombosis) can be another cause of leg pain. Pain in the knee and ankle joints of the leg is common with the arthritis conditions.
But as Dow's case shows, it can happen throughout the body. When it does, it's called peripheral arterial disease, or PAD. And in some people, PAD causes leg pain that acts as an 'early warning' that someone is at high risk for a heart attack or a stroke, says a University of Michigan Cardiovascular Center expert. Leg pain could be a sign of possible peripheral arterial disease.
