None of the articles you linked answered my question about how OMT would actually treat the migraine. If you can't explain how it works, how could you tell it's not just a placebo effect? It's been decades or more than a century since some of these techniques have been practiced, and we are still looking for evidence that they work 100 years after the fact.
Also, there's no need for personal attacks or psychoanalyses. If I wasn't curious about the subject why would I care at all? I already said that I do believe a good portion of OMT is useful and makes scientific sense. Even if I didn't, isn't it just as unintellectual to go through four years of DO school, learn all the ins and outs of every technique, spend hundreds of hours studying for in-house/board exams/practicals, and not question any of it? It's okay to acknowledge that many of the techniques and principles DO schools still teach exist so that DO's can be unique. I don't have an inferiority complex for saying that, and I think that line of thinking is more beneficial to the DO profession than blindly believing everything we've been taught.
