This. This. THIS.
I believe chiropractors can have a place treating conditions they are qualified to treat. I don't believe they are qualified to make diagnoses or universally treat all of the conditions they will lead you to believe they can treat.
When I was about 30 I started having random aches and pains in one arm and a chiropractor was my first response. Years and 3 chiropractors later, I had only gotten worse and ended up with pain in the other arm too. I finally wised up and went to a real doctor, got an MRI and found discs bulging into the space where the medial, radial, and ulnar nerves leave the spinal column in my cervical spine. A physical therapist was able to teach me a few exercises that will get rid of the pain almost immediately and it won't return for months or years. I firmly believe the chiro adjustments added trauma, which increased inflammation and swelling against those nerves and may very well have accelerated permanent damage. Yet even after they knew I wasn't getting better they kept letting me come in and pay them once a week.
I could see going back if I feel like my hips are out of alignment or something, but I'll never let another chiropractor touch my neck or try to treat nerve pain.
