Except that some of it is supported by research. We've rehashed this time and again in ATOT. For back pain, quite often, chiro care is just as good as PT or traditional medicine. And, iirc, some of the research spelled out that among those with equal results after 3 months, those receiving chiro care were the most satisfied during those three months.
After years of headaches starting in my neck area, I finally broke down & went to a recommended chiropractor. The headaches went away; required visits for a month or so. A couple years later, chronic headaches; he said just the one visit was going to do it. During one of those visits, he said, "hey, looks like you must be having numbness and tingling in your fingers." I hadn't thought anything of it - just considered that darn it, I've got carpal tunnel syndrome, and like my wife, I'll be having surgery in a few years for it. I think it was the C5 or something that he said something or other about. A crack or two, and that tingling went away. I was just thinking about it today - that numbness/tingling is back in my right hand after driving for a while. I just got done with hay season = lots of back breaking work; I must have done something. So, hopefully a visit will take care of it.
