📖What is Restless Legs Syndrome?
Restless Legs Syndrome is a neurological disorder characterized by an irresistible urge to move the legs, usually accompanied by uncomfortable sensations described as crawling, tingling, or aching deep within the limbs. Symptoms typically worsen during periods of rest or inactivity, especially in the evening and at night, and are temporarily relieved by movement, which can significantly disrupt sleep. The condition is believed to involve dysfunction in the brain's dopamine system and iron metabolism. It can occur on its own or alongside other conditions such as iron deficiency, kidney disease, or pregnancy.
