Anecdotes are useless, I could counter that with one where I went to a chiropractor and it did not help at all. My anecdote is just as useless I am glad your pain is gone, though.
What I really want to know is; was the chiropractor also claiming to cure cancer and the common cold? Was the place decorated with healing crystals and connected to a magic healing spa that would cure gout? Those are the ones that piss me off.
The reason I am fine lumping them together with the "real" chiropractors is that the "real" chiropractors do nothing to show that the quacks are quacks.
