How Pain is Processed in Our Nerves
Pain is a phenomenon that is deeply intertwined with the brain and nervous system. When something is wrong with the body, signals travel to our brain as neural impulses. These impulses are then interpreted by the brain as pain, which is basically the body's signal to us that we need to fix something.
