The uncomfortable sensation occurs when the blood supply to a part of the body is cut off for a short time. The blood flowing back into the affected area causes the brain to send 'messages' to the nerves in the part of the body where the blood flow was affected, producing that familiar feeling we call 'pins and needles'.
