I'm not a doctor so it would be unethical and irresponsible for me to diagnose anyone online. But I have a stretch therapy business and we relieve and reduce a lot of pain all over the body. Sometimes the person has pain in the lower back but the issue is tight hamstrings. I have also had people that have had issues such as different types of arthritis like rheumatoid arthritis, vascular arthritis, and bursitis is different locations of there body. Your case studies could try going to some specialist doctors or even going to a chiropractor. Just do your research for the chiropractors. Some are better then others and you should probably stay away from the franchise type locations. Not that the franchise locations are bad they just aren't set up to diagnosis any serious or hard cases. How are you involve in the case studies? I really don't have any context for anything you are telling me.
