Chiropractic medicine is bullshit, right?

My mother has been experiencing back pain for a few months now, and insists her chiropractor is making it "tolerable."

Whenever I plead with her to see a doctor or a physical therapist, or suggest that maybe the chiropractor is the problem she gets very upset with me. There is no convincing her of any alternative, she won't even get a second opinion and I'm not quite sure how to help at this point.

My sister got her got her an appointment to see a massage therapist, which she went to and said nothing but good things about, but she will not budge on the chiropractor.

I dunno maybe I'll just shut up about it, but it all just seems like quackery to me.
