What symptoms characterize intermittent claudication?

• A. Numbness and coldness in extremities
• B. Muscle pain during use that subsides at rest
• C. Severe swelling in legs and feet
• D. Persistent burning sensation in limbs

Answer: (B)

Intermittent claudication is characterized primarily by muscle pain that occurs during physical activity, such as walking, which then subsides during periods of rest. This symptom is due to inadequate blood flow to the muscles, often as a result of peripheral artery disease. As a person engages in exercise, oxygen demand increases, yet the narrowed arteries cannot supply sufficient blood, leading to pain in the muscles, typically in the legs. Once the activity stops, blood flow dynamics change, alleviating the pain and allowing the muscles to recover. Other symptoms mentioned, such as numbness and coldness in the extremities, severe swelling in the legs and feet, and persistent burning sensations, may relate to other vascular or circulatory issues but do not specifically describe the hallmark symptoms of intermittent claudication. Numbness may suggest nerve issues rather than purely vascular ones, while swelling often points to venous problems rather than arterial.
