• Peripheral artery disease (PAD) is a common circulatory problem where narrowed arteries reduce blood flow to the limbs, most often the legs.

• This narrowing is usually caused by a buildup of plaque (atherosclerosis) in the arteries.

• PAD can lead to pain, especially during exercise, and can increase the risk of heart attack, stroke, and other serious complications.

Symptoms

• Leg pain when walking.

•Muscle pain or cramping in the arms or legs, often in the calf.

• Pain when using the arms, such as aching and cramping when knitting or writing.

• Coldness in the lower leg or foot, especially when compared with the other side.

• Leg numbness or weakness.

•No pulse or a weak pulse in the legs or feet.
