Restless Leg Syndrome – Symptoms, Causes, and Treatment Options

Overview of Restless Leg Syndrome

Restless Leg Syndrome (also known as Willis–Ekbom disease) is a common but often underdiagnosed neurological condition. It affects up to 5–10% of adults worldwide, though prevalence can vary depending on the population and definition used (Allen et al., 2014, Sleep Medicine).

People with RLS describe it as an uncomfortable crawling, tingling, pulling, or aching feeling deep in the legs. These sensations are relieved only by movement—such as walking, stretching, or even just shifting position. The hallmark feature is that symptoms worsen at night, often leading to insomnia and daytime fatigue.

The condition impacts much more than just sleep. RLS can interfere with work performance, sports participation, travel, and social activities. Because symptoms typically peak in the evening, many people struggle to relax, spend time with loved ones, or fall asleep. Over time, poor sleep can also contribute to mood changes, anxiety, and depression.

Although RLS is not life-threatening, the ongoing discomfort and sleep loss can significantly lower quality of life. Many people find themselves avoiding long car rides, flights, or situations where they cannot easily move their legs. In families where multiple members are affected, RLS can disrupt household routines and relationships.

Symptoms of Restless Leg Syndrome

The primary symptom of RLS is the urge to move your legs, usually accompanied by unpleasant sensations. These feelings are often described as:

• Tingling or crawling under the skin
• Pulling or throbbing inside the muscles
• Aching or itching deep in the legs
• “Electric” or “creepy-crawly” sensations

Key Features of RLS Symptoms

• Worsen at rest: Symptoms are most noticeable when you are sitting or lying down.
• Relieved by movement: Walking, stretching, or even moving your legs around can temporarily ease discomfort.
• Evening and nighttime pattern: Symptoms are much worse in the evening and at night, leading to insomnia.
• Sleep disruption: Difficulty falling or staying asleep is one of the most common complaints.

Severity and Impact

RLS symptoms range from mild (occasional restlessness) to severe (daily discomfort that makes sleep nearly impossible). Severe RLS often leads to chronic sleep deprivation, irritability, poor concentration, and reduced work performance.

Red Flag Signs

If symptoms are sudden in onset, severe in intensity, or associated with weakness, numbness, or pain in other areas, it’s important to seek medical evaluation. These may signal another condition that needs attention, such as neuropathy or vascular disease.

Causes and Risk Factors for Restless Leg Syndrome

The exact cause of RLS isn’t fully understood, but research points to a combination of genetic, neurological, and lifestyle factors.

Neurological Factors

• Dopamine imbalance: RLS is linked to dysfunction in brain pathways that use dopamine, a chemical messenger that helps control muscle movement.
• Iron deficiency: Low levels of iron in the brain can affect dopamine activity. This explains why iron supplementation can help some people.

Lifestyle and Health Risk Factors

• Age: RLS can affect anyone but is more common with increasing age.
• Gender: Women are nearly twice as likely as men to develop RLS.
• Pregnancy: Up to one-third of women experience RLS during pregnancy, especially in the third trimester. Symptoms often improve after delivery.
• Chronic health conditions: RLS is more common in people with kidney disease, diabetes, or peripheral neuropathy.
• Medications: Certain drugs (e.g., antihistamines, some antidepressants, and antipsychotics) can worsen symptoms.
• Lifestyle factors: Obesity, sedentary habits, smoking, and high caffeine intake may increase risk or worsen symptoms.

Family and Genetics

Research shows that RLS often runs in families. If a parent or sibling has the condition, you are more likely to develop it yourself.

Diagnosis, Recovery, and Management of Restless Leg Syndrome

How do doctors test for Restless Leg Syndrome?

Restless Leg Syndrome is diagnosed based mainly on your symptoms, medical history, and a physical or neurological exam. Unlike many other conditions, there’s no single test or scan that can confirm RLS. Instead, doctors use a set of clinical criteria developed by the International Restless Legs Syndrome Study Group:

• An urge to move the legs, usually accompanied by uncomfortable sensations.
• Symptoms worsen at rest and are relieved by movement.
• Symptoms are worse in the evening or at night.
• Symptoms are not better explained by another condition (such as arthritis, leg cramps, or neuropathy).

Clinical Evaluation

Your doctor will usually:

• Ask about your symptoms, sleep patterns, lifestyle, and family history.
• Check for underlying conditions such as iron deficiency, kidney disease, or diabetes.
• Review medications that may worsen RLS, such as antihistamines or certain antidepressants.

Lab Tests & Imaging

• Blood tests may be ordered to check iron and ferritin levels.
• In some cases, tests are done to rule out neuropathy or other nerve problems.
• Imaging (like MRI) is rarely needed unless another neurological condition is suspected.

Because RLS symptoms can overlap with other disorders, doctors sometimes recommend a sleep study (polysomnography). This can reveal periodic limb movements during sleep, which are common in people with RLS.

Recovery Timeline for Restless Leg Syndrome

Recovery from RLS depends on whether your condition is primary (genetic or idiopathic) or secondary (linked to another health issue).

1. Mild cases: Symptoms may improve quickly with lifestyle changes, iron supplementation (if deficient), or short-term medication. Relief can occur within weeks.
2. Moderate cases: With regular management, symptoms can be controlled over months. Many people experience fluctuating symptoms throughout life.
3. Severe cases: Chronic RLS may require ongoing medication and lifestyle adjustments. Symptoms can be long-term, but severity often improves with treatment.

Long-Term Outlook

• Relapse risk: Even when well-managed, RLS symptoms often return if treatment stops.
• Pregnancy-related RLS: Usually resolves after delivery, though some women develop long-term symptoms.
• Secondary RLS: Improves when the underlying cause (e.g., iron deficiency, kidney disease) is treated.

Return to Daily Life

• Work: Most people can continue working with adjustments, such as taking stretch breaks or standing desks.
• Sport & activity: Exercise is usually encouraged, though excessive high-intensity activity may worsen symptoms in some people.
• Sleep & mental health: As sleep improves, so does mood, focus, and overall energy.

If untreated, RLS can progress and lead to chronic sleep deprivation, increasing risks for anxiety, depression, and reduced quality of life.

How to Manage Restless Leg Syndrome

Management focuses on relieving symptoms, improving sleep, and addressing underlying causes.

Self-Help & Relief Tips

If you have mild to moderate RLS, you can often reduce symptoms with simple lifestyle adjustments:

1. Stretching and walking: Light stretching before bed or short walks during the evening.
2. Heat or cold therapy: Warm baths, heating pads, or cold packs can reduce discomfort.
3. Sleep hygiene: Keep a regular bedtime, avoid screens late at night, and make your sleep environment comfortable.
4. Limit triggers: Reduce caffeine, alcohol, and nicotine.
5. Activity breaks: On long car rides or flights, stand up and move your legs regularly.

👉 Quick snippet-friendly tip: If your legs feel restless at night, try walking around your bedroom for a few minutes or doing gentle calf stretches.

Medical & Professional Management

If lifestyle changes aren’t enough, doctors may recommend:

• Iron supplements: For people with low ferritin levels.
• Medications: Such as dopamine agonists, anti-seizure drugs, or benzodiazepines (depending on severity).
• Addressing underlying conditions: Managing diabetes, kidney disease, or neuropathy can reduce symptoms.

Decision Pathway

1. Mild RLS: Try lifestyle changes first. If symptoms improve, continue self-management.
2. Moderate RLS: If symptoms persist, add iron therapy (if deficient) or discuss medications with your doctor.
3. Severe RLS: Requires long-term medical management, often with prescription medications plus lifestyle strategies.

Long-Term Management

RLS is often a chronic condition. The goal is not always a complete cure but to minimize symptoms, restore sleep, and maintain daily function. With consistent care, most people find a routine that keeps symptoms under control.

Multidisciplinary Coordinated Care for Restless Leg Syndrome at CARESPACE

Restless Leg Syndrome (RLS) can feel overwhelming because it affects both your body and your mind. At CARESPACE, you don’t just get one perspective — you get a team-based, multidisciplinary approach that blends physical therapy, lifestyle support, and mental health care into a single, personalized plan.

How does CARESPACE treat Restless Leg Syndrome differently?

Most traditional approaches to RLS focus on medication alone. While helpful, this often doesn’t address the underlying triggers like stress, sleep issues, or muscle imbalances. CARESPACE takes a broader approach by combining expertise across physiotherapy, chiropractic care, massage therapy, kinesiology, psychotherapy, nutrition, acupuncture, and fitness training.

This means your care plan doesn’t just reduce symptoms — it supports your whole-body health, improving both daily comfort and long-term outcomes.

👉 Example: You might start with a physiotherapy assessment to check leg strength and flexibility, while also receiving massage therapy for muscle tension and counselling for sleep-related stress. Together, these treatments provide relief that’s deeper and longer lasting.

A Team Approach Across Physical and Mental Health

CARESPACE recognizes that RLS is not just a physical condition. The urge to move your legs at night can cause chronic insomnia, frustration, and even anxiety. That’s why our approach combines physical therapies with mental health support:

Related Conditions for Restless Leg Syndrome

Restless Leg Syndrome (RLS) can sometimes be mistaken for, or overlap with, other conditions that cause leg discomfort. Knowing the differences helps ensure proper diagnosis and treatment.

• Leg cramps: Unlike RLS, cramps are sudden, painful muscle contractions, usually in the calf, that don’t improve with movement.
• Peripheral neuropathy: Nerve damage from diabetes or other causes can mimic RLS but often includes numbness, burning, or weakness.
• Parkinson’s disease: Both involve dopamine pathways, but Parkinson’s includes tremors, stiffness, and slowed movement.
• Varicose veins or vascular disease: These conditions cause aching or heaviness in the legs, often worse after long standing.
• Sleep disorders (like sleep apnea): RLS often disrupts sleep, but it can also co-exist with other sleep conditions.
