Restless Legs Syndrome (RLS) induces symptoms or uncomfortable sensations in the legs while the individual is seated, lying down, or attempting to sleep. These sensations may manifest in the calves, thighs, feet, or arms, including:
- Aching or burning.
- Creepy-crawly feelings.
- Pulling.
- Itching or tingling.
- Cramping.
- Pain.
- Electric sensations.
- Tension.
- Discomfort.
- Gnawing.
Some individuals may struggle to articulate the symptoms of restless leg syndrome. People with RLS often experience a strong and frequently irresistible urge to move or manipulate their legs.
Commonly Reported Patterns:
- Onset during inactivity: Symptoms commence or worsen when the individual is seated or lying down for extended periods, such as during car rides, flights, or while trying to sleep.
- Relief through movement: Symptoms typically diminish partially or temporarily with physical activity, such as walking or stretching, and tend to persist only while in motion. This compelling urge to move gives rise to the name “restless legs syndrome.”
- Evening exacerbation: Symptoms usually intensify in the evening and at night compared to the morning.
- Nighttime leg twitching: Some individuals with RLS may also experience periodic limb movements of sleep (PLMS), characterized by involuntary leg flexing and extending during sleep, often unaware of these twitching or kicking movements. In severe cases, these involuntary movements may occur even while awake.
RLS symptoms can range from mild to intolerable, and tend to worsen with age. Some individuals may experience periods of remission, where symptoms improve or cease for days, weeks, or months, or fluctuations in symptom severity. However, in most cases, symptoms eventually reappear. RLS is generally considered a lifelong condition, and currently, there is no cure available.
