I believe i have and have had Restless Leg Syndrome for quite a few years now. In the past have had unexplained bruises on my legs (mainly thigh area). The past weekend i worked out in the cold during the night shift. as i stood outside i could feel my shin muscles tightening. when i went to walk to my car i had full active charlie horses in both shins legs. at 4:00 am both legs completely cramped up and i couldn't move. I was unable to sit and needed to be placed into my car. I was unable to drive myself home. It is now three days later and i am still in lots of pain. Is this normal or is there a more severe, serious problem?
