Yes I had some bad discs (confirmed by MRI) but was able (via a rather brutal exercise program) to build up enough core strength to lower my pain level 95%.
It took several months, and it wasn’t fun, but I’m forever indebted to the phys therapists on this one.
95% is pretty amazing!
When I do what they told me to do, I’m fine for months or even years at a time. I have to keep the hamstrings flexible, and the lower back muscles in shape. It isn’t fun, but the stretching before bedtime actually seems to improve my sleep.
