What type of pain is associated with arterial insufficiency?

• A. Sharp, intermittent claudication
• B. Dull constant ache
• C. Burning in the joints
• D. Sharp throbbing pain at rest

Answer: (D)

Arterial insufficiency can progress from pain with activity to pain at rest as blood flow becomes severely limited. When perfusion is only enough to meet resting tissue needs, the pain often shows up even without movement. This rest pain is typically felt in the toes or feet and is described as sharp or throbbing, and it often worsens at night when lying flat because gravity no longer helps drive blood to the lower limbs. Elevating the legs can worsen symptoms, while placing the limb in a dependent position can temporarily relieve them by improving perfusion.

So, rest pain reflects advanced arterial ischemia, a sign that the disease has progressed beyond intermittent claudication (which is the pain that occurs with walking and stops with rest). The other descriptions fit different patterns: intermittent claudication is the exertional type, dull aches are more typical of venous issues, and burning in the joints isn’t the classic ischemic pain pattern.
