possibly, because when part of your body is numb you have a restricted flow of blood to that area. as such your nerves around that area are more acute.

Could be right but i would have thought that anywhere with a reduced bood supply would also feel numb like when you sit on your leg funny or lean against your arm and your hand goes numb.
