Patient was educated on the early findings of peripheral artery disease as follows:

1. The involved extremity can be cold to touch and appears light bluish in color.
2. The classic early symptom of peripheral artery disease is leg pain when walking, which often resolves with rest. This pain is called intermittent claudication.
3. This is due to the muscle of the leg needing more oxygen during exercise, such as, walking.
4. More oxygen supply to the limb can be provided by improving blood supply, as hemoglobin in the blood carries oxygen.
5. But, since the arteries in the extremities are narrowed, increased blood supply to meet the demand of more oxygen can be difficult.
6. So, muscle in the limb hurts, as it is starving for the oxygen during exercise.
7. Pain in the limb characteristically settles with rest during the early phase of the condition.
