Hi, for more than 10 years I have had Restless Legs Syndrome. The degree of this illness could be categorized as severe. In the past few years additionally I now have problem with a sensation of skin crawling on my chest, comes in waves every 30-45 seconds. Like RLS it mostly but not exclusively occurs when lying down. Together between being sleep deprived and frequently unable to take naps for the same reason, it is affecting my ability to function. Age 67, I am very healthy and active otherwise, still working full time, and would like to continue to do so. Steve
