What are the symptoms of PAD? How do I know if I am at risk?

Patients with PAD usually present with buttock and hip, thigh, calf, or foot pain. They may experience pain or cramping in their leg muscles that develops with activity, is relieved with rest, and recurs upon resuming activity (intermittent claudication). Men may present with erectile dysfunction. Some patients notice a discoloration of their toes or may develop leg ulcers that do not heal in more advanced cases.
