I have been having body parts go numb. I'm scared, it's like they are almost asleep. Sometimes it happens to one side of body..then a leg or arm, then the other side of body. Usually when i lay down at night it is worse. Could this be poor circulation? Last night my right leg was so tingly, numb that it hurt from deep inside, I couldn't rub it out. Does anyone else do this? It's freaking me out..
