Restless Legs Syndrome

Overview

Restless legs syndrome (RLS) is a condition characterized by an uncontrollable urge to move the legs, usually resulting from uncomfortable sensations. It typically occurs in the evening or during nighttime when a person is sitting or lying down. Moving the legs temporarily relieves the unpleasant feeling. RLS can disrupt sleep and interfere with daily activities. Symptoms include an urge to move the legs, sensations that begin while resting, relief with movement, and worsening of symptoms in the evening. The sensations, which are generally described as crawling, creeping, pulling, throbbing, aching, itching, or electric, occur within the limb rather than on the skin. It's common for symptoms to fluctuate in severity. If you think you may have RLS, it's important to talk with your health care provider.

Understanding the disease

Symptoms

The chief symptom of restless legs syndrome (RLS) is an uncontrollable urge to move the legs, usually due to uncomfortable sensations. Common accompanying characteristics include:

  1. Sensations that begin while resting, typically after lying down or sitting for an extended time.
  2. Relief with movement, such as stretching, jiggling the legs, pacing, or walking.
  3. Worsening of symptoms in the evening.
  4. Nighttime leg twitching, possibly associated with periodic limb movement of sleep.
  5. Compelling, unpleasant sensations in the legs or feet, which may include:
    • Crawling
    • Creeping
    • Pulling
    • Throbbing
    • Aching
    • Itching
    • Electric sensations Symptoms usually occur on both sides of the body and may be difficult to describe. They occur within the limb rather than on the skin. It's common for symptoms to fluctuate in severity, with periods of remission followed by flare-ups. If RLS symptoms are affecting your sleep and daily life, it's important to consult a healthcare provider for proper evaluation and treatment.

Development

Restless legs syndrome (RLS) can develop due to various factors, including genetics, lifestyle, and medical conditions. While the exact cause of RLS is not fully understood, it's believed to be related to an imbalance of the brain chemical dopamine. Some people may be predisposed to RLS due to genetic factors, as it tends to run in families. Certain lifestyle factors can trigger or exacerbate RLS symptoms, such as:

  1. Sedentary lifestyle or prolonged sitting or inactivity
  2. Certain medications, such as antihistamines, antidepressants, and some antid

Assessment and Diagnosis

Triage

You should see a doctor if you suspect restless legs syndrome (RLS) if the condition is interfering with your sleep and causing daytime drowsiness, affecting your quality of life. Even if you have doubts about the seriousness of your symptoms, it is important to consult with a healthcare provider to discuss your concerns and receive appropriate guidance.

Diagnosis

To diagnose restless legs syndrome (RLS), your healthcare provider will take your medical history and ask about the nature and frequency of your symptoms. They will also conduct a physical and neurological exam. The diagnosis of RLS is based on the following criteria established by the International Restless Legs Syndrome Study Group:

  1. A strong, often irresistible urge to move the legs, usually accompanied by uncomfortable sensations.
  2. Symptoms start or worsen when you're resting, such as sitting or lying down.
  3. Symptoms are partially or temporarily relieved by activity, such as walking or stretching.
  4. Symptoms are worse at night.
  5. Symptoms cannot be explained solely by another medical or behavioral condition. Your healthcare provider may also order blood tests, such as iron deficiency tests, to rule out other possible causes for your symptoms. If you have other health conditions or are experiencing symptoms that may be related to RLS, it is essential to discuss these with your provider to ensure proper management of your overall health.

Management and Treatment

Complications

Potential complications of restless legs syndrome may include excessive daytime sleepiness, which can lead to difficulties at school or work, or problems with everyday tasks, disturbed sleep, embarrassment about the sleep terrors or problems with relationships, and injury to oneself or rarely to someone nearby.

Home Remedies

Home remedies for restless legs syndrome (RLS) may include:

  1. Relaxation techniques: Practicing relaxation techniques such as deep breathing, meditation, or yoga can help alleviate stress and promote better sleep.
  2. Regular exercise: Engaging in regular physical activity during the day can help reduce symptoms of RLS. However, avoid exercising too close to bedtime as it might increase energy levels and make it harder to fall asleep.
  3. Warm or cold baths: Alternating between warm and cold baths can help alleviate RLS symptoms. Some people find that soaking in a hot bath followed by a cold shower helps reduce the unpleasant sensations.
  4. Massage: Regular massages can help relax the muscles and ease RLS symptoms.
  5. Good sleep hygiene: Maintaining good sleep habits, such as consistent sleep and wake times, a comfortable sleep environment, and avoiding stimulants like caffeine and nicotine can improve sleep quality and potentially reduce RLS symptoms.
  6. Avoiding triggers: Identifying and avoiding factors that can aggravate RLS symptoms, such as stress, anxiety, and depression, can help alleviate the condition.
  7. Quitting smoking: Smoking can worsen RLS symptoms, so quitting smoking might help improve the condition.
  8. Avoiding alcohol and caffeine: Both alcohol and caffeine can exacerbate RLS symptoms. Limit or avoid their consumption, especially in the evening. It's important to note that these remedies may not work for everyone with RLS, and individual responses may vary. Consult a healthcare professional for personalized advice and recommendations.
