In peripheral arterial disease, elevating the legs typically causes:

Explanation:
Elevating the legs lowers the hydrostatic pressure at the feet, reducing the arterial perfusion pressure to the leg tissues. In peripheral arterial disease, the arteries are already narrowed, so this drop in perfusion worsens ischemia and triggers more pain. That’s why increasing leg pain is the expected response to leg elevation. The physiological effect is decreased perfusion, but the question focuses on the clinical symptom, which is pain; elevation would not improve claudication.
