Restless Leg Syndrome

Restless leg syndrome (RLS) is a disorder that causes uncomfortable sensations in the legs, typically accompanied by an uncontrollable urge to move them. These sensations can range from mild discomfort and tingling to painful cramping or burning, and are often described as feeling like pins and needles or a creeping crawling sensation under the skin. While anyone can develop RLS at any age, it is most common in adults between 30 and 60 years old.

What Causes Restless Leg Syndrome?​

The exact cause of RLS is still unknown, but research suggests that it may be linked to an imbalance of dopamine, a neurotransmitter in the brain that plays a role in movement control. Other potential factors include genetics, iron deficiency, and underlying medical conditions such as diabetes or kidney disease. Certain medications like antidepressants, antihistamines, and some sedatives can also trigger RLS symptoms.

Symptoms​

Symptoms of RLS typically begin after prolonged periods of sitting or lying down and often worsen at night, disrupting sleep patterns. Some people may experience additional symptoms such as:

  • An urge to move the legs, which is usually accompanied by an uncomfortable sensation in the affected limb.
  • Sensory disturbances like tingling, numbness, or pain in the legs.
  • Mood changes, including anxiety and irritability.

Diagnosis​

Diagnosing RLS can be a bit tricky since its symptoms are similar to those of other conditions. A healthcare professional will typically ask about your medical history, perform a physical examination, and may order some tests (like blood work or imaging studies) to rule out underlying causes of the symptoms. The diagnosis is usually made based on a combination of these factors.

Treatment​

Treatment options for RLS vary depending on the severity of the condition. Some people find relief with lifestyle changes like getting regular exercise, managing stress through relaxation techniques, and avoiding triggers such as caffeine or nicotine. For others, medication may be necessary to alleviate symptoms. In some cases, dopamine agonists (medications that mimic the action of dopamine) may be prescribed to help manage RLS.

Living with Restless Leg Syndrome​

While there's no cure for RLS, there are ways to manage its symptoms and improve overall quality of life. People with RLS often find it helpful to establish a regular sleep schedule, stay physically active, and engage in activities that promote relaxation and reduce stress.
