Internal Medicine

Restless Legs Syndrome (RLS) is a common cause of uncomfortable leg sensations, often described as tingling, crawling, aching, or pulling. These feelings typically worsen in the evening or at night and create a strong, often irresistible urge to move the legs for relief. RLS can disrupt sleep, affect daytime energy, and impact overall quality of life.

Because leg discomfort can also point to other conditions—such as circulation issues, nerve problems, or mineral deficiencies—it's important to understand what may be driving your symptoms before deciding on next steps. Taking a free, instant, online symptom check can help you narrow down possible causes, identify red flags, and get personalized guidance on when to see a doctor. It only takes a few minutes and could save you hours of uncertainty.

Explanation

Restless Legs Syndrome (RLS) is a condition that can cause an uncomfortable feeling in the legs. People with RLS often feel like they need to move their legs, especially in the evening or when they are trying to sleep. This can make it hard to get a good night's rest.

Key Points about RLS:

Symptoms: People with RLS feel unpleasant sensations in their legs, such as tingling, burning, or itching. These feelings usually happen when they are resting or lying down.
Relief: Moving the legs often helps relieve the uncomfortable feelings.
When it Happens: Symptoms typically occur in the evening or at night, which can make it difficult to fall asleep or stay asleep.

RLS can affect people of all ages, but it is more common in older adults. If someone thinks they might have RLS, they should use a free symptom checker to better understand their symptoms and discuss the results with a healthcare provider to find ways to feel better.
