People that are affected by restless leg syndrome (RLS) experience uncomfortable sensations in their legs and feel the urge to move them to feel better temporarily. These feelings most often occur in the legs but can also affect the arms or other parts of the body. The discomfort is usually worst in the evening and when the legs are at rest and you are sitting or lying down. Restless leg syndrome may begin at any age, affects about 10% of the population, and although it occurs in both men and women it is more common in women. The cause of RLS is unknown, although about half of people affected also have at least one family member that is also affected. The development or worsening of RLS may be affected by chronic diseases (such as Parkinson’s disease, kidney failure, or diabetes), medications (antinausea drugs or antidepressants among others), and pregnancy. This condition is diagnosed by your symptoms since there is no medical test for it. However, blood tests and other exams can be used to rule out other disorders. RLS can be alleviated by hot baths, massages, or lifestyle changes including: implementing a regular exercise program, maintaining regular sleep patterns, and limiting use of tobacco, alcohol, and caffeine. Drugs such as dopaminergic drugs, benzodiazepines, narcotic pain relievers, and antiseizure drugs can also be used to treat RLS.
