Spinal nerves relay sensation messages from the body to the spinal cord and brain, and relay instructions from the brain to the body. Pain to and from a particular region in the body is transmitted via known spinal nerves. In addition, direct irritation of a spinal nerve can cause pain messages to be transmitted to the brain from that spinal nerve. The brain interprets these messages as originating in the region of the body that usually sends messages to the brain via that spinal nerve.
