2974,
I think I saw that there is or was a forum here for that, but what is it, a blood circulation problem? because the word "restless" seems to indicate a nervous problem. I know that if you're sitting down for a while and leaning your elbow on your leg, you have a momentary blood circulation problem when you stand up. If it is the conflicting or accumulation of medicine when you lie down, that would be circulation. It sounds like your doctor never really explained a cause, yet they have a reason to give it a certain name???????????????????????????
As far as it being a bonafide affliction (instead of a money scheme), maybe the doctors are just 'pulling our legs' (sorry, couldn't resist).
