Easy explanation!!! It can happen the upper extremity as well. You just clamp down on one of the major arteries and stop the
flow of blood to the l;eg. Then you begin walking and it goes away. Not dangerous if you do not have compromised circulatory
problems in which case I would avoid those positions which causes the legs to fall asleep.
