Introduction
-
Restless leg syndrome (RLS) is a difficult neurological disorder in which the sufferer is unable to completely control his legs at all times. The syndrome is fairly common, with an estimated 1 percent of the population suffering from it (RLS Society Statistic). Restless leg syndrome produces a nagging urge to keep moving your legs. The urge is usually accompanied by additional stimulation in the legs that feels like crawling or tugging in the muscles and skin.
Genetics
-
Restless leg syndrome is believed to develop because of genetics. Research has shown that many people diagnosed with RLS have family members who also suffer from the disorder. In fact, about 50 percent of people with RLS are related to someone who is affected (National Institute of Neurological Disorders).

Prescriptions
-
Certain prescription medications are also believed to bring on the sensation of restless leg syndrome. The most common of these medications include anti psychotics (like haloperidol), anti-nausea medications (like metoclopramide) and anti-seizure medications (like phenytoin). Some cold and allergy medications are also currently being studied as potential triggers for restless leg syndrome (NINDS).
Pregnancy
-
Pregnancy may also cause restless leg syndrome to develop. Medical professionals are unsure exactly why RLS can occur during pregnancy. However, the disorder usually develops around the last trimester and is gone within 3 to 4 weeks after the birth of the child.
Caffeine
-
Caffeine and other stimulants are also believed to contribute to restless leg syndrome. Stimulants excite the nerve endings in your body, which can trigger uncontrolled movement of the legs and other parts of the body. Eliminating caffeine and other stimulants may reduce the effects of RLS, but may not cure the disorder completely.
Disease
-
Restless leg syndrome may also be a symptom of a much more dangerous disease. Parkinson's disease, diabetes, and kidney failure all count RLS as a possible symptom to be used for diagnosis.
