An intriguing truth about the spine is that when you feel significant pain, such as banging your palm against a door, your body will remember it as well as your brain. For a few days, the neurons in your spinal cord send pain signals to the nerves in your wounded hand. As a result, your hand will be more sensitive, and even little touches will elicit an uncomfortable and unwanted sensation. This occurs because your spine stores a memory of pain. Furthermore, because your spine has a long memory, you should treat and care for it from an early age. Control your posture, exercise, and stretch your back muscles to ensure your spinal cord's long-term health.
