I understand the desperation part. I remember it all too well myself. Going from doctor to doctor, hoping that one would provide THE ANSWER! Yes, I too got the kind of response of "Well, those symptoms sort of fit disease X, so here's a prescription to try.", but of course the drugs didn't work because having a couple of vaguely defined symptoms in common with a disease doesn't mean that you really do have it. If you listed several of your symptoms and did a search for diseases that matched them, you'd probably get thousands of matches, and that's only for known diseases. If you did exhaustive testing, I expect you'd find quite a few differences from what is supposed to be standard/normal results, but I think that would be true of a typical healthy person (we all have our minor abnormalities), and that treatments to 'fix' those differences would mostly not have an effect on your ME.
None of my successes with treating my ME came from doctors or from test results. Most came from paying attention to changes in my ME and then figuring out what caused them. LDN was something I read about, possibly here on PR, and thought it was worth trying, and it worked for me. Food poisoning cured me of type IV food sensitivity that started with my ME, so that was just pure (Happy!
) accident. T2 and cumin were from observations of unexpected improvement, and other improvements came from noticing what things to avoid.
Someone else here on PR is a proponent for exhaustive testing and treatments based on the abnormalities found, and says that doing so was worthwhile for him. It's not a one answer fits all issue. Maybe someone will recommend a doctor and claim wonderful improvements from that doctor.
I think part of the problem is that some PWME have definite comorbid conditions that testing can find, and can then be treated, for noticeable improvements, and thus success stories. Other people lack the simple issues that can be found that way. I had several doctors tell me that I appeared to be among the healthiest patients that he had, because all the medical tests showed normal results. The tests didn't cover whatever is involved in ME.
For me personally, I'll wait until someone figures out what to test for for ME. I think that improvements from even the most well-known ME specialists are unlikely. Too many disappointments from doctors so far, I suppose.
