A defining symptom of Restless Leg Syndrome is...

• A. Uncontrollable urge to move legs
• B. Choking during sleep
• C. Loud snoring
• D. Morning headaches

Answer: (A)

Restless Leg Syndrome is defined by an uncontrollable urge to move the legs, usually accompanied by uncomfortable sensations that begin or worsen during rest (sitting or lying down) and in the evening or night. The urge is typically relieved by movement, which is the hallmark feature that distinguishes RLS from other sleep-related issues. This pattern of worse symptoms at rest and at night with improvement with movement drives the characteristic sleep disturbance and daytime fatigue.

Choking during sleep, loud snoring, and morning headaches point toward sleep-disordered breathing or airway issues rather than the leg-focused urge of RLS. While morning headaches can occur with sleep apnea due to intermittent hypoxia, they are not the defining symptom of restless legs.
