The “pins and needles,” “internal itch,” or “creeping, crawling sensation” of restless leg syndrome (RLS) make it quite difficult to fall asleep, especially since those symptoms occur more often when one is sleepy or lying down and are relieved only by vigorously moving the legs. The symptoms of RLS may awaken one out of sleep, forcing the sufferer to walk around to relieve the discomfort.
Most people with RLS also have periodic limb movement disorder (PLMD), repetitive movements of the toe, foot, and sometimes knee and hip during sleep. These movements may cause arousals that lead to non-restorative sleep. Your doctor can prescribe various medications to reduce or eliminate the movements and the associated sleep disturbances (arousals) caused by these disorders. This results in a more sound sleep, one from which you awaken restored and refreshed.
