If you were saying that it was just your legs I would think that it is restless leg syndrome but since you said it is your hands too I would think that you have poor circulation. I would talk to your doctor about it, poor circulation isn't something that you want to ignore.
Im trying to get into see the doctor. Was just wondering if anyone else has had this promblem also. But it seems strange that it only happens when I go to bed.
I hope you get an answer. I have this problem too when I sleep. Its not every night but it happens on and off. I don't have insurance so i can't go to a doctor.
It happens to my mom too, she is going today to get it checked out.
