This is good to read about, and nice that it has and research referenced.
It's interesting to know that it's gas collapsing. And nothing to do with the bone rubbing.
And it makes you wonder what chiropractors are actually doing when they're popping your back... It's probably not doing anything to help you with your pain. And it's probably not actually adjusting anything.
If a chiropractor could adjust something by pushing on your bone, imagine what tripping and falling would do.
Chiropratic can help with pain, but not for the claimed reasons. Studies show it's as efficacious as massage therapy. I believe the same is true of cupping. Insurers increasingly cover these sorts of therapies, and primary's increasingly prescribe them, because they're cheaper than a real doctor's time, especially a specialist's, and the patient is more likely to feel better than if they were subjected to a long diagnostic gauntlet with an inconclusive end.
There is a chain of clinics here called "Emergency Chiropractic" and they advertise how they take insurance and get your adverse diagnosis fast, fast, fast.

And their mascot is literally a duck! I think it took me ten years to figure out the quack part here!
It's surprising that it's not common knowledge that "Chiropractic" is not medicine, nor a science, and the field is associated with vaccine misinformation and unproven supplements.
I recommend reading up on the actual history of chiropractic ... I've seen articles that seem to make it clear that it was long con right from the start.
I acknowledge that this is not the only view on the history.
