My brother recently sent me some reading material which has steered me in this direction. Greens are very rich in vitamins, minerals, fiber, enzymes and amino acids. When we cook them, some of the nutrients are lost to denaturing by heat. We also tend not to eat enough of these foods for our health. I was hoping for an overall boost in immunity and well-being, but not knowing what to expect. I've been happy to have reduced back pain since a few days after adding raw greens to my diet. As I said, it may be coincidence. I tend to eat a lot of vegetables anyway, but I have now increased my consumption of raw dark leafy veggies by whipping them up into smoothies with fruits like bananas, apples, oranges, etc. They look odd, but taste quite refreshing.
Stretching (especially back extensions) has helped me somewhat with herniated disk pain and sciatica. I've also found it helpful to keep up my fluid intake. Disks contain a lot of moisture, and if they're dehydrated, they have less cushioning capacity.
These are all conservative measures which should do no harm, and may do some good. Good luck.
I've heard about increasing my liquid intake before but had forgotten. First on my list of resolutions this year is getting my back healthy and now I'm going to increase raw greens in my diet!
Happy New Year!
