Most of our doctors do seem to have their own, um... preferences. I feel there's a large amount of "To the man who has a hammer, everything is a nail" in ME/CFS treatment. I tried to list those docs who seemed to have the most tools in their toolkits (to keep the analogy going). I suspect that if we could get roadmaps from, say, the four docs I listed, we might be able to combine them into some coherent whole. However, I don't think getting the knowledge those docs use down on paper is in any way an easy feat. I wonder if we could, by polling patients, find out which tests are commonly run by the top 10 (or 20) ME/CFS docs. The two I've seen both ran many tests, including tests for infections. It might give us a good starting point. Of course, the way they evaluate the results of the tests is also critical. My local GP ran a bunch of tests, but decided there was nothing wrong while my ME/CFS specialists came to different conclusions from similar tests. I think Lyme and herpesvirus tests are particularly susceptible to significant interpretation difference, for example.
