Can claudication be a possible symptom of peripheral arterial disease?

Yes: Patients with intermittant claudication(pain with walking, usually involving the calf muscles, but can be higher)may have blockages or narrowing of their arteries that go to the leg, thereby decreasing the amount of available oxygen for active muscles.

A principal symptom: Claudication, or the tensing up of the calf muscles during walking, is the main symptom of peripheral arterial disease. It is caused by blockages in the arteries that give blood supply to the calf muscles. Claudication may be called "intermittent" because it goes away when one stops walking and may recur on resuming walking -unlike spinal stenosis which causes rest pain down the legs.

Absolutely: Claudication is one of the cardinal signs of pad.
