I don't know much about Montoya but you could be correct, since we have no disease mechanism and no approved treatment we don't have a huge arsenal to attack the disease with.
We can try to work on the symptoms, digest new research and work on finding the mechanism/cause and we can do our best to make sure people are not being diagnosed with ME/CFS who don't have it. Treating comorbid conditions can also be done. We can also accept some people do improve spontaneously and its likely a percent of the improvements would have happened with no treatment given and its coincidence. Once we have a disease mechanism we will know more and be able to research this better.
All this said doesn't change anything i said about KDM.
No, but it does change the implication of it. If what you said about him applies to all the other ME physicians, then the implication is that seeing ANY ME physician is fraught with risk. If that is the implication, then it would be more accurate to phrase it like that. Some people only seem to care about KDM though.
