The symptoms described in the scenario (leg tingling, aching, and movements to relieve the discomfort) are characteristic of restless legs syndrome, which is a sleep disorder. Hypnic jerk syndrome involves sudden, involuntary muscle contractions or jerks that occur when falling asleep, but without the tingling or aching sensations. Somnambulism (sleepwalking) and REM behavior disorder both involve abnormal behaviors during sleep, but neither is associated with the leg sensations described in the scenario.
