What Are the Signs and Symptoms of Peripheral Artery Disease?

Many people who have peripheral artery disease (P.A.D.) don’t have any signs or symptoms.

Even if you don't have signs or symptoms, ask your doctor whether you should get checked for P.A.D. if you're:

• Aged 70 or older
• Aged 50 or older and have a history of smoking or diabetes
• Younger than 50 and have diabetes and one or more risk factors for atherosclerosis

Intermittent Claudication

People who have P.A.D. may have symptoms when walking or climbing stairs, which may include pain, numbness, aching, or heaviness in the leg muscles. Symptoms also may include cramping in the affected leg(s) and in the buttocks, thighs, calves, and feet. Symptoms may ease after resting. These symptoms are called intermittent claudication.

During physical activity, your muscles need increased blood flow. If your blood vessels are narrowed or blocked, your muscles won't get enough blood, which will lead to symptoms. When resting, the muscles need less blood flow, so the symptoms will go away.

Other Signs and Symptoms

Other signs and symptoms of P.A.D. include:

• Weak or absent pulses in the legs or feet
• Sores or wounds on the toes, feet, or legs that heal slowly, poorly, or not at all
• A pale or bluish color to the skin
• A lower temperature in one leg compared to the other leg
• Poor nail growth on the toes and decreased hair growth on the legs
• Erectile dysfunction, especially among men who have diabetes
