The chemicals released by the body when an injury occurs or when the body has other abnormal processes taking place actually make changes to the nervous system. The types of changes they make are related to the type of pain you feel.
The brain controls all our bodily functions, but there are three things it cannot do: 1  It cannot feel pain. The brain can feel pain from all over the body, but not within itself. 2  The brain cannot store oxygen. A person can feel a lack of oxygen after only a few seconds. 3  The brain cannot store glucose (blood sugar).
