Acupuncture intrigues me. I don't have the foggiest idea how it works--and no acupuncturist can explain it to the satisfaction of any Western doctor--but it is occasionally very powerful.
I have used finger acupuncture to stop full-blown migraines in a couple of patients (using a finger-pressure technique I learned from--guess who--a chiropractor I know pretty well).
Actually, I don't have a problem with incorporating those types of modalities into a practice. My problem is that Chiro's entire premise is based on a lie, subluxation. There are some chiros that admit that they're really not sure exactly why adjustments help lower back pain, but that they are convinced they do, so they treat patients accordingly, and that's fine. But when I see patients who are being "treated" for sinus or gastric problems, or I hear about chiros recommending their patients NOT VACCINATE their kids, that's when I have a problem.
