Overview
Peripheral artery disease is a condition of the blood vessels that leads to narrowing and hardening of the arteries that supply the legs and feet.
The narrowing of the blood vessels leads to decreased blood flow, which can injure nerves and other tissues.
What are the symptoms of Peripheral arterial disease?
The classic symptoms are pain, achiness, fatigue, burning, or discomfort in the muscles of your feet, calves, or thighs. These symptoms usually appear during walking or exercise and go away after several minutes of rest.
- At first, these symptoms may appear only when you walk uphill, walk faster, or walk for longer distances.
- Slowly, these symptoms come on more quickly and with less exercise.
- Your legs or feet may feel numb when you are at rest. The legs also may feel cool to the touch, and the skin may look pale.
When peripheral artery disease becomes severe, you may have:
- Impotence
- Pain and cramps at night
- Pain or tingling in the feet or toes, which can be so severe that even the weight of clothes or bed sheets is painful
- Pain that is worse when you raise the leg and improves when you dangle your legs over the side of the bed
- Skin that looks dark and blue
- Sores that do not heal
