The most common form of PAD is caused by atherosclerosis . The arteries most commonly affected are those that carry blood to your legs. Lack of blood to these areas causes the symptoms associated with PAD.
Calf or thigh pain with exercise is termed claudication. Claudication is a sign of PAD. The discomfort may consist of cramping, limping, or a feeling of heaviness, weakness, or fatigue in the legs. Symptoms of claudication usually begin after walking a certain distance—such as a block or two—and end after resting for the same length each time.
Many people will have no symptoms at all. In those that have them, PAD may cause:
- Numbness of the legs or feet at rest
- Cold legs or feet
- Muscle pain in the thighs, calves, or feet
- Loss of hair on the lower extremities
- Paleness or blueness of the legs or feet
- Weak or absent pulse in the extremity
- Walking troubles
- Foot wounds that heal slowly
