Ice causes the veins in the affected tissue area to constrict. This reduces the flow of blood while acting as kind of anesthetic to numb the pain. But when the ice is removed (and this is key), the veins compensate by expanding, which then allows a large volume of blood to rush to the affected area. The blood brings with it important chemicals that aid in the healing process.
