What you say is very interesting, because I have suffered thoracolumbar back pain for decades, and lately the intensity of the pain has increased. The doctors looked at my back thousands of times; they ordered countless tests (MRI, X-rays, scans, …) and the cause of that pain never appeared. I was always told that I might have a condition called "spondylitis" but it was never proven or diagnosed. After decades of fruitless searching, I gave up searching and tried my best to deal with chronic pain. I don't take any pain medication as I already take too many to prevent another heart attack. I only take a few paracetamol from time to time, because it's the only thing doctors allow me to take.
But I think your idea is good, and maybe I need to see a specialist doctor. It may be time for a spinal checkup.
Thank you very much for the advice!
