Even though this is top comment, this is an underrated answer.

People always chime in with stories about how chiropractors helped them with XY and Z problem they were having.

And overall I don't doubt them. There's a lot of things that can go wrong with your spine or other joints, and I'm certain that some of them can be addressed by physically manipulating and adjusting it.

But the basic premise of chiropractic treatments is that basically all human ailments can be fixed in that way, which should sound like total bullshit to anyone with half a brain. And that's before you get into all spiritual nonsense that pervades a lot of the field.

Now some of them understand that that's a load of bullshit and may even be realistic about the things they can treat, but it can be pretty damn hard to sort them out from the ones who think that your pancreatic cancer is caused by ghosts in your spine and they know how to get them out or some bullshit like that.

Now if you have a good idea what your issue is and what needs to be done to fix it, take the time to carefully vet your chiropractor to make sure they're not going to try some crazy bullshit on you, you very well may be able to get a decent treatment from them. Maybe you'll even be able to save some money going with that.

But for most of us who aren't doctors and so only have kind of vague ideas what exactly the issue is and that the treatments we're doing actually make any sense, and don't necessarily have time to do all of that research and carefully vet that the person treating them isn't secretly a quack, you could just get the same sort of treatments from actually physical therapists, orthopedists, physiatrists, etc. with the added benefit of them actually understanding the issues and how to fix them properly.

Chiropractors are kind of like the rednecks of the medicine world. Some of them know exactly what they're doing with that harbor freight welder, they may not do things by the book but they know for certain what works and what doesn't and more importantly know when something is beyond what them and their buddies can accomplish on a free Saturday with a case of beer and when they need to suck it up and limp their truck to the shop and let a professional deal with it. Others know just enough to be dangerous and while they can get the job done 90% of the time or at least not make things worse, that 10% of the time something is literally going to blow up in someone's face. And still others are just meth heads looking to make a quick buck and it's a miracle they're not behind bars. And when you see them hanging around the local watering hole, it may not be totally clear which is which until it's too late.

Also homeopathy.

The entire industry is built on catering to the vast swaths of women who get ignored by doctors and need somewhere to turn.

I highly suspect doctors are taught in medical school, "women are over emotional and prone to exaggeration."

Hell, "hysteria" was considered a valid diagnosis until the 1950s.

Not all chiropractors are the same, but not knowing who's who is dangerous
