I come from a family of chiropractors and have seen first hand what an amazing healing specialty it can be. No it cannot cure every ailment, but for a bad back, neck, and a whole host of other problems, it can accomplish miracles.
I took my own kids to my chirpracric family members since birth(they are all adult now) and it really helped them when they were sick or had headaches. I myself went to them throughout my pregnancies, and my sciatica went away LITERALLY in an instant. I remember vividly the day I could not get up off the floor, I was in so much pain, and my brother adjusted me right where I lay, and a second later the pain was completely gone. I thank Hashem for giving over such a talent into the hands of specialists who do not need to rely on drugs to be effective. When drugs are necessary, they are a miracle, but when chiro care can help, it too is miraculous. (And yes, you can hear a POP).
