> I've also started to doubt that PEM is a reliable indicator of having ME/CFS.
can we assume you mean that if you have pem, you might not have me/cfs?
are there e.g. rare diseases, with objective signs, that have the enormous number and diversity of symptoms that can occur in a single pwme? including "weird" symptoms? e.g. mold intolerance and and whatever else doctors hate?
that number and diversity and weirdness made me feel incompetent to figure it out. y2kish i scoured harrisson's and lange's internal medicine textbooks and found nothing with that kind of number and diversity and weirdness.
pretty thiiiiiiiiiiiiiick textbooks. did i need a rare diseases textbook instead?
wegener's granulomatosis, maybe [should i get tested?]?, and a bunch of diseases like sle with "and other symptoms"; thanks guys, that's real helpful there; mind mentioning them and the number that is possible to have at the same time?
i guess hiv/aids was about as close as wegener's [name changed to Granulomatosis with Polyangiitis].
cfs was there with like ONE SYMPTOM and reassurance as the treatment. reassurance that WHAT?
the potentially big thing, i think, is that i found NOTHING with the weird symptoms, circadian, intolerances, oi, exec dysfunction, dysauto, allergies, etc., number, or diversity. now i have more, angioedema, etc. also, there is something else that sticks in my mind:
for a long period, every few months to a year, i got a new disease that never went away. what disease does that? what metadisease?
so, for concreteness, suppose maybe it is sle. it's common and supposedly can have all sorts of symptoms. i test positive on anti-ds dna for sle. supposedly very high specificity except for a virus you can test for or so.
but my doctor said my clinical picture does not match. where can i find that picture? those textbooks were useless for finding anything. there is no picture to match the clinical picture to. "and other [!@#$] symptoms."
what persuaded me that m.e. is viable was not pem, but circadian, rare in general but common in m.e. in ccc. recent results in e.g. genetics.
surely, if all pwme have some existing thing, we'd know about that by now? idk.
behcet's or whatever. which, i still don't know if it has objective signs and the number, diversity, and weirdness.
i find subjective resonance in the experiences of pwme. is overlapping common? is it confirmation bias?
i remain really confused by pem, unto even the, almost taboo, opposite of what i think you are saying [i.e. if you don't have pem closely as described by certain descriptions of it, it seems you might still have m.e.] exertion takes a lot out of me and can lead to permanent harm.
pem as a concept seems just too confused imo. at least for severe? the permanent pem thing, the immediately vs. 24h delay, whether pem is the same as a crash, the limitation to cognitive physical and sometimes emotional as opposed to lots of other intolerances also, whether it is a symptom or a metasymptom, which symptoms get worse, etc. the confidence in pem out there in pem as a pathognomon confuses me given the confusion surrounding it.
i get that presentations vary a lot though. and i get that pem is a clear and distinct thing to observers, even if it varies. what severity levels are they though, what diversity of symptoms, what number, what weirdness?
and then there are mold, lyme, etc. [which, could be m.e.]. dysautonomia, mcas too. symptom? cause? quite confused!
