What is Pain? What is its Purpose?
Pain is a warning system and the body's method of telling us that something is wrong. Pain is essential; without it, abnormal conditions may go undetected, causing damage or injury to vital parts of our bodies.
Even though pain is a necessary warning signal of trauma or malfunction in the body, nature may have gone too far in its design. Aside from its value in diagnosis, long-lasting persistent pain serves no useful purpose. Pain doesn't begin until a coded message travels to the brain where it's decoded, analyzed, and then reacted to.
The pain message goes from the injured area along the small nerves leading to the spinal cord. Here the signal is switched to different nerves that travel up the spinal cord to the brain. The pain message is then interpreted, referred back, and the pain is felt.
