Tiredness when walking and cramping or pain in your lower extremities could mean you have peripheral artery disease, or PAD. The American Heart Association says the disease often goes untreated by health-care professionals because they can mistake it for something else. It’s important to understand the signs and symptoms so you can have an educated discussion with your doctor.
The AHA says PAD is the narrowing of the peripheral arteries to the legs, stomach, arms and head. It is most common in the arteries of the legs. PAD is caused by atherosclerosis that narrows and blocks arteries in these critical regions of the body. People who have PAD are at a much higher risk for a heart attack or stroke.
