I am not going to say most, since I do not know that, but far too many chiropractors are just heavy pushers of woo woo. A lot of the stuff that you will hear from them is nonsenses. If they oppose vaccinations you know that you have a purveyor of woo.
I can agree that there's probably far too many pushing woo, but there's far too many doctors behaving in less than desirable ways, too.
I remember when my heart problems started cropping up, the attitude was very laize faire from doctors, who said it was probably just anxiety. It took a long time to find someone to investigate(it wasn't anxiety). One of my kids also ran around with a staph infection for 6 months(we saw 5 different doctors) because the doctors were too proud to run a swab test(because I suggested it might be staph, and what does a patient know?). I finally found one in an urgent care who did so(it was staph). The doctor and nurse on that visit helped me find a good doctor for the kids; I've been happy with him. I am happy with the chiropractor I've seen for years(since before my 16 year old was born, actually). He's helped with SVT symptoms, hyperactivity in the middle child, and other aches and pains.
I suspect you're best off finding a medical professional who will listen to you, and whom you know is pulling for you. If they can't help, they probably know someone in the right profession who can, and who will care and listen.
