In my experience of at least 5 chiros, 2 oesteos, and 2 Physios for lower back pain – the Oesteo was far more in depth and have helped a lot. It’s a common misconception that a chiropractor is quackery but I wouldn’t agree, certainly for manipulation of joints in fact this can be fine by your GP. The quackery mantra comes from all the other stuff surrounding the health of the spine. However I would say chiropractors are the most vague at solving problems and certainly don’t spend much time after a while.
Physios were the least successful too me and very old school, in that they always get you to do more core work and don’t seem to be interested in much else.
Bottom line, still have a tight lower back, but manage it with Oesteo, lots of home massage using triggerpoint stuff and lots of lying down.
I can keep doing my 10-12 hours a week on the bike without much problem, but it’s never going away. The gp/NHS were useless and I quote , “whilst you keep doing what you are doing you will always have a tight spine/lumber.” Useful.
