People with restless legs syndrome have uncomfortable sensations in their legs (and sometimes arms or other parts of the body) and an irresistible urge to move their legs to relieve the sensations. The condition causes an uncomfortable, “itchy,” “pins and needles,” or “creepy crawly” feeling in the legs. The sensations are usually worse at rest, especially when lying or sitting.
The severity of RLS symptoms ranges from mild to intolerable. Symptoms can come and go and severity can also vary. The symptoms are generally worse in the evening and at night and less severe in the morning. For some people, symptoms may cause severe nightly sleep disruption that can significantly impair a person’s quality of life.
In most cases, doctors do not know the cause of restless legs syndrome; however, they suspect that genes play a role. Nearly half of people with RLS also have a family member with the condition.
Other factors associated with the development or worsening of restless legs syndrome include:
• Chronic diseases. Certain chronic diseases and medical conditions, including iron deficiency, Parkinson’s disease, kidney failure, diabetes, and peripheral neuropathy often include symptoms of RLS. Treating these conditions often gives some relief from RLS symptoms.
• Medications. Some types of medications, including antinausea drugs, antipsychotic drugs, some antidepressants, and cold and allergy medications containing sedating antihistamines may worsen symptoms.
• Pregnancy. Some women experience RLS during pregnancy, especially in the last trimester. Symptoms usually go away within a month after delivery.
Other factors, including alcohol use and sleep deprivation, may trigger symptoms or make them worse. Improving sleep or eliminating alcohol use in these cases may relieve symptoms.
Massage is frequently recommended as a way of providing relief from RLS. Other recommendations include regular exercise, hot or cold baths, weight loss and quitting smoking. But massage has additional benefits.
Massage improves circulation. The National Institute of Neurological Disorders and Stroke theorizes that poor circulation may be related to Restless Leg Syndrome. Massage is known to boost circulation, because the pressure provided by your therapist helps move blood through congested areas.
Releasing that pressure makes new blood flow in, while also improving circulation of the lymph fluid that removes metabolic waste from your muscles and internal organs. It adds up to improved body function as well as lower blood pressure.
