I must of seen over 30-35 different ones over the years and NONE of them can manage my case (I get over 90 different symptoms with the ME). Thou I are in Australia.. my case is still a good example as primary care doctor situation wouldnt be any different to Amercia.
I'm not sure about Australia, but an American PCP can't be directly compared to, say a British GP. Our PCPs (the ones who are MDs or DOs; some PCPs are allied health practitioners like Physician's Assistants and Nurse Practitioners) typically have specialist training in either Family Medicine or Internal Medicine, though we don't actually title them 'specialists.'
The Internists typically feel more competent (than the Family Medicine practitioners do) to deal with a complex illness like this (supposing they have some idea that it is a true and complex illness), and may be able to somewhat manage a moderately complex case if they are intelligent and ambitious (being that we don't actually have too many specialists--hardly any normal rheumatologists, endocrinologists, neurologists, immunologists, etc. know anything about this disease, and many of our very few ME/CFS specialists started out as PCPs anyway--and you have to educate a lot more specialists to get well-rounded care than if you target generalists).
Of course it would certainly be much better to have a team of specialists (immunologists, heart rhythm doctors, endocrinologists, and so forth) well-trained in ME/CFS to manage patients, but one still needs a primary care physician to coordinate care between the specialists even in this ideal situation.
Where to begin education of nearly every doctor in the world (or, those falling in the responsibility of CFSAC directly, in the USA) is a bit daunting, but since everyone is supposed to have a primary care physician of some sort who, ideally, finds specialists for us who at the very least aren't prejudiced (not to mention having a faint idea what ME is), I won't quibble with starting there.
We have to start someplace.
Maybe rheumatologists would be just as good a goal, though, as they are used to dealing with patients like us... but they seem unwilling to keep politically incorrect diseases and might resist being given another (in addition to fibro). While I think we do have pathologies that would fit nicely in the rheumatological classification (autoimmune, joint, and muscle disorders), we don't have anything that is classically like their other patients. At least not until someone designs us better blood tests, which I would expect to be readily doable given funding and a sensible scientific approach, both of which have been sadly lacking.
Neurologists would be even better, and even given our strong immune dysfunctions I think we fit very well with them (very like Myasthenia Gravis, Multiple Sclerosis, mitochondrial disorders, and so on) but I think they are unreachable just now. Half their patients (I read on another thread) have diseases they cannot identify and they this basically represents personal problems of the patients. They would classify us with these. A paradigm shift is necessary in the world of medicine.
I'm not familiar enough with immunologists to suggest those. I think given the differences in how we should be managed versus diabetes, endocrinology is not a good idea for a 'home base' for us.
My experience with cardiologists suggests they are not likely to take us on. Also given the differences in how we should be managed versus many cardiac patients and the fact that the best cardiac testing for us is uncommon and perhaps experimental, this seems an unlikely 'home base' for us.
So I still think PCPs is not an awful suggestion for where to begin. The danger is that they do not leave off after having begun.
