Why after getting pins and needles does your part of the body go cold?!

Its because you applied pressure to the veins that facilitate blood flow to that part of your body!. The nerves do not have adequate blood flow so go into a "numb" state, and once the blood flow returns, they need to "wake up" again, Kind of like rebooting the computer- everything has to reload!. That's why it feels cold and the "pins and needles" are your nerves trying to get a sense of what's going on!. It won't hurt you but feels awful and the first instinct is to bang or shake your hand, which is actually natures way of trying to get the blood into that area faster!.Www@Answer-Health@Com
