Exercise is part of improving the structure. It improves the nutrition to the joints, tissues and muscles. I have not found any yet that work since my FMS got me. My inhalers do not work anymore. Herbal, I have great success with Tumeric, but I'd suggest working with a person, either a doctor or herbalist, who knows what he or she is doing.
Spinal surgery is rather invasive jump.
Try gentler approaches first. I have two patients for whom spinal surgery did not work. The disks were fused. I don't have any more information. In closing, I'd like to tell you all that I've observed that people with these diseases require prolonged and a very specific therapy that incorporates physicians and healers of different specialties, both naturopathic, homeopathic and alopathic.
