Pain worsens the situation by conditioning one to not move the area, when immobilization is the worst possible remedy for the pain! We need joint mobility or we rob the disc of its nutrition. Basically acting like a sponge, the disc receives nutrition from physical exercise, which causes it to swell and then squeeze out fluid. However, pain can influence us to avoid physical activity, and thus prevent the much needed nutrients from washing the area. Without nutrition washing our discs, decay begins. We are as old as our joints, so our only chance at a fountain of youth comes from drinking from the well of joint mobility.
