What is restless legs syndrome and its hallmark symptoms?

• A. Urge to move legs with uncomfortable sensations, worse at rest and at night; relief with movement
• B. Chronic cough
• C. Chest pain on exertion
• D. Frequent headaches

Answer: (A)

Restless legs syndrome shows up as an urge to move the legs accompanied by uncomfortable sensations. The key pattern is that these sensations begin or worsen when you’re resting, especially in the evening or at night, and they’re relieved by movement. This combination—uncomfortable leg feelings plus an urge to move that gets worse with inactivity and at night and improves with activity—is what distinguishes RLS from conditions like chronic cough, chest pain on exertion, or headaches, which don’t have this leg-focused urge-to-move pattern.
