Restless Legs Syndrome, Uncomfortable Leg Sensations

Hello. This is Baengnokdam Korean Medicine Clinic.

"Why do my legs feel strange only at night?"

A woman in her late 50s has been experiencing an unpleasant sensation in her legs every night for the past 3-4 years, making it difficult for her to sleep. This sensation is not pain, but is described as a crawling, tightening, or burning feeling.

The symptoms worsen particularly when she lies down, and while moving her legs provides temporary relief, the sensation returns when she lies down again, preventing deep sleep.

Two years ago, she was diagnosed with Restless Legs Syndrome (RLS) and has been taking dopamine-agonist medications, but her symptoms are progressively worsening. Due to poor sleep, she also experiences chronic fatigue, depression, and heart palpitations.

Moreover, she recently recalled her mother experiencing similar symptoms in her childhood, leading her to wonder, "Could my mother also have suffered from RLS?"

Restless Legs Syndrome: What's the Underlying Issue?

1. Characteristics of Restless Legs Syndrome

• Characterized by uncomfortable leg sensations that worsen at night and are temporarily relieved by movement.
• Can disrupt sleep, leading to chronic fatigue, depression, and other issues.
• Has a strong genetic component, often with a family history.

2. Causes

• Dopamine Neurotransmission Dysfunction: Dopamine deficiency or imbalance is considered a primary cause.
• Iron Deficiency: Iron deficiency can affect dopamine metabolism and neurotransmission, potentially worsening symptoms.
• Stress and Sleep Deprivation: Psychological and environmental factors can also exacerbate symptoms.

Dopamine-agonist medications are commonly prescribed, including the following:

1. Commonly Prescribed Medications

• Dopamine Agonists
  • Pramipexole (brand name: Mirapex): A first-line treatment that activates dopamine receptors to alleviate symptoms.
  • Ropinirole (brand name: Requip): Similar to pramipexole and widely used for RLS.
• Iron Supplements: If iron deficiency is confirmed, iron preparations are co-administered to improve neurotransmission.
• Benzodiazepines (Sedatives)
  • Clonazepam (brand name: Rivotril): Calms the nerves to reduce symptoms and induce sleep.
• Neuropathic Pain Medications
  • Gabapentin (brand name: Neurontin): Alleviates nerve hypersensitivity to reduce symptoms.

2. Problems with Pharmacological Treatment

• Augmentation: Dopamine-agonist medications can lead to augmentation over time, where their effectiveness diminishes or symptoms worsen.
• Side Effects: Long-term use can cause side effects such as nausea, dizziness, and palpitations.
• While medications can temporarily alleviate symptoms, they may not always eliminate them completely.

Korean Medicine Treatment for Restless Legs Syndrome

RLS is not solely a problem of dopamine dysfunction; the overall balance of the body, particularly blood circulation, nervous system stability, and relief of mental stress, are also crucial. Korean medicine treatment can help address these comprehensively.

1. Herbal Medicine Treatment

Herbal medicine is prescribed based on the patient's condition, with the following objectives:

• Improving Blood Circulation and Stabilizing Nerves: Improves blood circulation in the legs and calms hyperactive nervous responses.
  • Herbs: Prepared Rehmannia Root (숙지황), Angelica Root (당귀), Cnidium Rhizome (천궁), White Peony Root (백작약).
• Improving Sleep and Psychological Stability: Alleviates psychological anxiety and heart palpitations, promoting restful sleep.
  • Herbs: Sour Jujube Seed (산조인), Longan Aril (용안육), Lily Bulb (백합), Licorice Root (감초).
• Iron and Energy Supplementation: If iron deficiency is suspected, herbs with high iron content are used.
  • Herbs: Astragalus Root (황기), Poria (복령), Ophiopogon Tuber (맥문동).

2. Acupuncture Treatment

Acupuncture treatment is effective in directly addressing the neurological and circulatory issues of RLS.

• Acupoint Stimulation: Reduces leg discomfort and calms the nervous system.
  • Key acupoints: Zusanli (ST36), Sanyinjiao (SP6), Taichong (LR3), Yinlingquan (SP9).
• Improving Sleep: Alleviates stress and tension to promote restful sleep.
  • Key acupoints: Shenmen (HT7), Xinshu (BL15), Pishu (BL20).

3. Lifestyle Management

• Warm Therapy: Keep legs warm before bed to promote blood circulation.
• Iron Intake: Consume iron-rich foods and, if necessary, take iron supplements.
• Stress Management: Restore psychological stability through meditation, yoga, etc.
• Regular Exercise: Engage in light aerobic exercise to relax leg muscles.

Restless Legs Syndrome can be improved with Korean medicine treatment.

RLS is not merely a problem of dopamine dysfunction. Various factors such as poor blood circulation, nerve hypersensitivity, iron deficiency, and psychological stress interact complexly to worsen symptoms. Korean medicine treatment can comprehensively address these underlying causes, restore the balance of body and mind, and fundamentally alleviate symptoms.

Even when symptoms do not improve with conventional drug therapy, Korean medicine treatment and constitutional improvement can help restore quality of life. Consider Korean medicine treatment for better sleep and health.
