What characterizes cramping in the lower extremities that is relieved by rest?

• A. Intermittent claudication
• B. Venous insufficiency
• C. Raynaud's phenomenon
• D. DVT

Answer: (A)

The main idea is exertional leg pain caused by insufficient arterial blood flow, which is relieved by rest. This pattern—pain that appears with walking or exercise and improves when you stop moving and rest—is called intermittent claudication. It happens in peripheral artery disease when atherosclerotic arteries can’t increase blood flow enough to meet the muscles’ higher oxygen demand during activity. Rest reduces the muscle demand and allows time for the limited blood supply to meet needs again, so the pain fades. In contrast, venous insufficiency tends to cause aching or heaviness, swelling, and visible changes in the skin; symptoms are worse with standing and often improve with leg elevation rather than with rest from exertion. Raynaud’s causes color changes in the extremities from vasospasm (usually of the fingers or toes) triggered by cold or stress and is not described as exertional leg cramps relieved by rest. Deep vein thrombosis presents with unilateral leg swelling, warmth, and tenderness rather than exercise-induced cramping relieved by rest. So, cramping in the legs during activity that is relieved by rest is characteristic of intermittent claudication due to arterial insufficiency.
