Many people don’t know that there are two kinds of physicians in this country: the M.D. (the Medical Doctor) and the D.O. (the Doctor of Osteopathy). Both are licensed physicians, both go to four-year medical schools, both go into every field of medicine (from Family Practice to Brain Surgery and everything in between). There are two differences between M.D.s and D.O.s: the first is that D.O.s are taught to view the patient as a "body/mind/spirit whole", which makes them somewhat more "holistic". The second difference is that in addition to learning all of the medicine and science that their M.D. colleagues learn in medical school, D.O.s also learn a field of hands-on medicine called Osteopathic Manipulative Medicine (also currently known as Neuromusculoskeletal Medicine). You might be somewhat familiar with OMM / NMM if you have been to a chiropractor: D.O.s learn the same techniques that chiropractors use , but they also learn how to work with every joint in the body, with the muscular system, the lymphatic system, the nervous system--in short, all the bodily systems, including working on organs themselves.
