Restless legs syndrome is a syndrome that patient feels an uncomfortable and strange feeling on the legs but he can not describe exactly; and as a result of this feeling he can not fall asleep. As a rule, patient feels this strange feeing while he rests; and complains about the inability to explain it to other people and to doctors. Because, this feeling – which can not be called as pain- is sometimes described as tingling, numbness, pull out of legs by the patient. Some patients describe this feeling as “my legs are being squeezed”. Patients get rid of this feeling only if they move their legs. Patient feels relaxed for some time after moving the legs; but would start to feel the same feeling only a few minutes later.
