Eh. To me a doctor is a doctor, no matter what letters follow your name.
As far as being looked at as less than M.D. Yeah, maybe. But the question is by whom? Patients? Maybe an actual physician can comment on how many patients a day ask him or her if he or she is an MD or DO. I asked a DO that had been practicing for about 10 years, he said he had that question maybe 3 times in his entire career. And it wasn´t even MD or DO, it was where he attended medical school.
By your colleagues? If I were a physician, I just can´t see myself losing sleep over what opinions my MD colleagues may or may not have about me. Any sleep loss would be over my patients, and that´s it. I guess you can let it bother you if you choose to. But people are always trying to appear better than their neighbor. It´s human nature in my opinion. Right now, the conversation is MD and DO, but among residencies, the conversation will be ¨oh I´m smarter because I matched in Dermatology and you matched in Peds,¨(Nothing wrong with peds by the way). Among surgeons, the conversation will be Neurosurgery being above General Surgery. The nonsense hierarchies will never end.
As far as OMT being a hoax. Eh, maybe. I have had it done on me and I have found it to be very beneficial. But who knows, maybe it was one giant placebo effect. Either way, I still walked away feeling better, and isn´t that the point? For the sake of argument, let´s say that it is fake. So? You still receive the same clinical training as an MD. You learn the exact same basic sciences. I would have to say go and get some exposure, then make the distinction.
As far as ¨doors being closed.¨ Eh, maybe. I know what DOs usually match into, but is it because that´s their only choice or because they are fine with that? I don´t know. I know that the majority of DOs go primary care, but there are also plenty that match into other specialties. I just don´t know if I believe that if a DO kills the COMLEX and USMLE exams he or she will not have a decent shot at the residency of his or her choice. But I could be wrong, maybe I´ll get lucky and an actual residency director can correct me.
I guess the biggest question is, do you really care? The law doesn´t, nor do compensation rates, because DOs and MDs have the exact same practice rights
But hey, if you are looking to go into something like neurosurgery, statistically speaking you would have a better shot as a US MD, and if that's what you want that is great! Good luck with your decision!
