@robertwwh : Seems strange that your MRI does not really show anything, but the doctors still think degenerated lumbar disc, perhaps. IF that is the case, some old fashioned, boring, core strengthening exercises may help with that. I’ve had a squashed, dried out lumbar disc for about 35 years, developed chronic back and sciatic pain 11 years ago, have been doing a 5-minute exercise set EVERY morning for 6+ years. Keeps things moving and mostly pain free. Of course, this may not be the cause of your pain, but it definitely cannot hurt to try. Give it at least 6 weeks to see if pain improves.
