One should not forget that cartilage has no arteria/vene system to provide nutrients to the cells and to rid them of the metabolic garbage. This is only done by passive diffusion, driven by compression/decompression of the e.g. discs. And cartilage has no nerves. So the body has to make up pain if it thinks something is wrong, based on some at least to me atm not known parameters in the tissue around the cartilage. The best medicine for backpain is physical activity, especially with respect to the mentioned compression/decompression. The human body is made for walking, so that is one good treatment. But in some cases it may not be enough, and more special physical exercises may be needed. If you understand German, the YT vids of Liebscher-Bracht helped me a lot. But general flexibility training should in most cases be enough. With mental exercises, one may get rid of the pain, and that might be enough in cases where it is a mere misinterpretation ,or wrong fixation of the interpretation, of the cartilage status. But e.g. a disc bulge is definitely a pathological condition. One that in many many cases can be healed with rather simple physical exercises. A good muscle 'armor' around the joints can prevent the pathology and often attenuate the severeness of done damage. So please exercise. Being dependent on medics and health systems adds to the decapacitation which is todate en vogue. Sapere aude!
