"If your entire arm is numb that means you either slept on your shoulder the wrong way or slept with your neck in a funny position, affecting the nerves coming directly from the spine," Anthony Kouri, MD, orthopedic surgeon at the University of Toledo Medical Center who treats patients with sleep related issues, tells Bustle. If your arm numbness is related to your neck, stretching your neck out or moving it in a certain way can help to alleviate the numbness and tingling. "If you notice that raising your arm above your head improves your numbness and tingling, that is a tell-tale sign that you have a pinched nerve in your neck," he says.
