I live next door to a chiro place. The couple who run it are both chiros. I have had a bad back on and off for years, they sorted it. My missus works in health regulation, and knows just how shonky many chiros and osteopaths can be, so I went into the treatment with my eyes open, and asked both about the dodginess. They were completely upfront, explained they don’t do all the odd energy centre stuff, but operate on medical principles.
Anyway, went there 3 times, and they sorted out my back, and a dodgy shoulder I’d had for about 3 years.
There may be shysters, I may be a amazingly prone to placebo effects, but it worked for me.
To be clear, I’m trying to suggest that a good chiro can help, I’m not saying all chiros are legit.
