What Causes Numbness In Arm During Sleep?

I wake up in the middle of the night and my entire arm is numb, if I sleep on my side, the arm opposite the side I am laying on is the numb arm. It happens every night for the last few months. It s starting to really concern me. I am an RN, and can t think of a reason this would happen.

General & Family Physician,  's  Response
Hello dear,
cause of a tingling hand or arm is simply the result of sleeping on your arm or hand for a long period of time. The pressure of your body's weight can disrupt nerve pathways and circulation to that particular part of the body.
The flow of nutrient-rich blood to tissue in the arm can be restricted because the arteries are being compressed.
As a result, nerves in the arm can't always send the proper signals to the brain and understand the signals that are being sent out from the brain. The disruption of nerve communication can then leave your hands or arms asleep until better blood flow is restored.

So it is no serious problem.
Just take sleep in proper position.
Hope this may help you.
Take care
