To the OP:
Without spending time to read the other responses, I'll give you my perspective. So I apologize in advance for repeating anything anyone else may have said.
I suffer from low back pain and fairly often will have flare ups of severe low back pain. I have seen many physicians for this problem and feel that in my case I can begin to generalize... insofar as to say that it all depends on the practitioner. The difference between MD and DO philosophy, collectively, is that the DO's have a uniting philosophy whereas the MD's do not. The DO philosophy is to consider both the host and the disease in the continuim of the illness process. We take into account all factors contributing to the host (environment, structure, impaired function, etc.). Many individual MD institutions, and MD students and practitioners have adopted a similar philosophy, but there is no uniting philosophy binding all MD education.
As a further illustration, though, of how it all depends on the practitioner, one must take into account the mindset of the individual applying the treatment. If that person (whether she be a DO or MD) does not have any vested interest in such a philosophy, then their mode of practice will follow suit.
I have been to many a physician (DO and MD) who could care less about the whole patient philosophy. The majority of these have been MD's but that only reflects the proportion of MD's to DO's that I've seen for my dysfunction.
I will say that since becoming a medical student, I have been undergoing a lot of stress (which in my case usually elicits a physical and immune response). I have been less sick (ie fewer colds, URI's and other problems) since I've become a regular OMM guinea pig to my classmates and the second year students. I've also suffered from a case of the flu almost every year since childhood. I have yet to get the flu this year (no vaccine) despite being surrounded by family members who have. Also, the few times I've felt "under the weather," the duration of this sickness has been much less this year. Is this proof that OMM and the DO philosophy works, not necessarily, but it is one more piece of anecdotal evidence.
I welcome anyone who wants to slam my perspective, but as I stated before, this is my perspective and my opinion only.
peace...
