Flue like - I feel comfortable with ‘flue like’ in that often I find it hard to know if I am in PEM or coming down with a virus, which is something that others also report. This did mean in my very early stages I could not distinguish between my presumed triggering infection (glandular fever/mono/acute EBV) and ongoing symptoms that would eventually be diagnosed as ME/CFS.
I can get a runny nose or even chest pains akin to the start of bronchitis linked to PEM, making even harder to distinguish it from some sort of infection, meaning it may take a few hours or even a day or so until the course of the PEM makes it clearer that it is not an emerging infection.
Like a hangover - Often when describing PEM to people I will say ‘flue like’ or ‘as though I have ‘a severe hangover’. I find it useful using both together. The hangover wording raises the experience of feeling poisoned that many report, but also by using both together it makes it clear I am striving for comparators rather than intending to be taken literally.
Currently I have a headache, nausea, mild discomfort in my throat and mild yuckiness. I currently I can not be certain whether this is just a general ME/CFS impact, particularly because I have just woken and it usually takes a couple of hours to recover from sleeping, or if I am coming down with something, or I have developing PEM. A review of my recent activity, I did go on a brief shopping trip 48 hours ago but spent the time since mainly lying down, makes the first option the most likely, but I will not be sure until after my tablets I have gone back to bed for several hours.
Complex multi system - I am not advocating the use of this phrase and I do understand why it is just plain wrong, but it does crudely explain an aspect of ME/CFS that I feel needs to be expressed. Namely that the symptom configuration does not superficially fit into how medicine divides up illnesses and diseases. We have symptoms that cross the divide of different bodily systems and do not fit comfortably into how medicine in terms of its specialisms divivies up the patient/disease universe. Would using a phrase along the lines of ‘diverse symptoms that can appear in multiple biological systems’ help?
