A patient with bilateral leg pain and purple discoloration that improves when the feet are elevated most strongly indicates which condition?

• A. Arterial insufficiency
• B. Intermittent claudication
• C. Venous insufficiency
• D. A psychosomatic episode

Answer: (C)

The situation points to venous insufficiency. When the veins in the legs aren’t returning blood effectively, blood pools and venous pressure rises, leading to edema and skin changes such as a purple or hemosiderin-stained discoloration. Elevating the legs helps venous return, decreases this venous pressure, and often relieves the symptoms, which is why the described improvement with elevation fits venous pathology. Arterial insufficiency would typically present with leg pain that is worsened by elevation (since arterial blood flow is further reduced when the leg is up) and skin changes like pallor, coolness, and diminished pulses, not a purple discoloration that improves with elevation. Intermittent claudication refers to exertional leg pain from arterial disease that subsides with rest, not a pattern driven by leg position and edema. A psychosomatic episode wouldn’t usually produce objective vascular discoloration and edema.
