Why do your fingers and toes hurt so bad as they get warm after being so cold?



  1. 0 Votes

    This is because when your fingers and toes are cold, they constrict blood flow and to limit the amount of energy the heart needs to pump in order to supply blood for the body. This is why frostbite can claim toes and fingers because the capillaries constrict and cut off blood flow to protect the internal organs. When you warm your hands, capillaries open and blood rushes in. The warmth from your blood against your cold hands creates the pain which is really just a sensation within the nerves in your hands.
