So far, when I've compared "Locations Effect" notes with the other people who have classic ME and who are successfully pursuing extreme avoidance (i.e. according to Erik's instructions), our assessments of different places have been remarkably similar. I was really surprised at just how similar, at first.
I'm talking here in terms of triggering just the specific disease symptoms themselves though. I'm not talking about things like avoiding cold, wind, rain, heat, sun, high altitudes, noise, insects, allergens, trashy places/people, or pollution that, while unpleasant, does not lead to ME symptoms (as defined by the ME ICC criteria).
These are all people who believe that toxic mold was a big factor in kicking off their illnesses though (e.g. who were living in particularly moldy places when they got sick). And they all report classic ME case histories.
I've occasionally talked to some people who have MCS but who seemed to have had their illnesses kicked off by big exposures to some other substance (such as pesticides or industrial chemicals). My feeling is that these people may indeed have somewhat different reactivities than I do, and thus may feel better or worse in different places. This would be consistent with the idea that they have different "primaries" than I do.
I'm not convinced that these people have classic ME though. Frequently their illnesses would get them a CDC CFS diagnosis, but that's not exactly the same thing. ME seems to me to be more specifically a biotoxin illness -- mold, Lyme, ciguatera, cyanobacteria, other outdoor biotoxins.
Of course, all of this is speculative. Until we get some research into the phenomenon, or at least larger numbers of reliable reports, it's hard to know whether ME type symptoms are triggered by the same toxins/locations in all people with this disease, or even whether all people with ME are triggered by toxins at all. And the facts that locations can vary over days or seasons, and that just driving a few miles can make a huge difference in some places, makes this even more difficult to piece together.
That's why I really appreciate hearing reports on different locations, from a variety of people. This is not a perfect methodology for learning about what's going on, but at least it's a start.
Thanks very much to folks for considering contributing their experiences, therefore.
