So if we are talking about “what’s going on with ME”, and throwing some ideas into a mixing pot, here are a few of mine:
(There have been a few more posts as I was typing…. )
1.
Adrenalin:
I can perform much better under adrenalin’s influence. As a biologist I recognise it as the “flight or fight” hormone. So basically it is about survival in the moment. Blood is diverted away from the gut, and towards the brain and muscles ready for action. Pain signals are also down-played, so the body is able to respond with less inhibition.
I won’t deny, I love a little adrenalin in my system.
However, as an ME patient, I find that once in my system, adrenalin leaves rather more slowly than I’d like.
A friend and I coined the phrase “dangerously okay” to describe the period when adrenalin fools you into believing you are better than you really are. This phase lingers even after an activity has drained the muscles of their energy. I KNOW I should be laying low, but I find it really difficult to appropriately rest in this state. It seems I don’t get PEM until after this phase passes.
2.
Gut:
I have found I do active things better on an empty stomach. This may be because “doing stuff” involves adrenalin which diverts blood away from the gut, so of course it’s better if there isn’t a load of food in there. I regularly skip breakfast, and always on the days I’m going out to work my dogs.
3.
Compression Wear:
So it seems if I want to do something a bit more active (eg my dog agility rounds which involve about 40 - 50 seconds of high concentration and co-ordination of my muscles - I’m just walking but none-the-less this is “active” effort). Lower body compression wear helps keep me on my feet for this, and means my brain able to keep thinking. This suggests to me that my peripheral blood vessels don’t respond correctly when I up my effort levels, because without compression wear, I quickly feel un-coordinated and sort of drunk (without the happy part).
4.
PEM:
PEM feels like an immune reaction to something. This seems to tie in with its delayed response (48+ hrs after the event for me) and with PEM’s incapacitation. ‘Flu leaves you feeling sore all over, sensitive to light, sensitive to noise, without an appetite, and unable to get-up and go-on. As I understand it, these symptoms are down to the immune system fighting whatever virus is causing the ‘flu. PEM for me feels like this too. Whereas in the 24 hours after activity, I can feel like I’ve escaped the PEM reaction (no doubt the adrenalin), the “day after, the day after” brings home the truth.
5.
If PEM is an immune response, to what is the immune response directed?
So here I’m feeling about in the dark.
A) Might it be that the gut gets “leaky” and our immune system fights some of those larger molecules that slip into the blood stream? This might connect with my observation that I “do better” on an empty stomach. Maybe if there’s less in the gut, then less leaks out of it? Who knows.
B) Might it be that the poor response of the peripheral blood vessels causes “something” to get flushed from the tissues to the lymphatic system, where an immune response is initiated to that particular molecule?
C) Might the fact that my muscles are highly fatiguable and the consequent anaerobic respiratory processes mean some weird respiratory by-product is produced at levels that sets off an immune response??? (Not sure on this one…).
D) Maybe the lack of production of ATP (cos anaerobic respiration can’t keep up) and the eventual conversion of ADP to AMP, could not only leave use drained of physical energy but also lead to other metabolic pathways that delay our ability to recover appropriately?
6.
Energy Ceiling?
None of these things seem to account for the fact that each ME individual has an energy ceiling effect.
What factor accounts for its level? Why is it relatively consistent over time? Why does it occasionally change for the better or worse? If over exertion causes it to drop what is the mechanism for that drop? If an antiretroviral drug causes it to lift (as happened for me during 2016) why is that? What was the mechanism for the change?
What is it that sets the level for each person’s energy ceiling? What can we do to nudge the ceiling up again?
All we know now is that normal rehabilitation involving exercise is counter-productive. Why is that?
It also seems that rest, although essential for maintaining a current energy threshold, doesn’t necessarily help the threshold to re-adjust upwards. Though a waiting game of rest, may eventually mean that some natural change happens to restore a better energy level…. Or of course, it may not!
7.
Boom and Bust
?
So here’s the thing, NO-ONE ever does the same amount each day! Not one person! We all go through cycles of doing a bit more, and then doing a bit less.
So if I choose to rest today and tomorrow, so I can do something a bit special the next day, and fully plan in my rest and recovery for the few days afterwards, then why should I not do that?
I have been doing exactly this for the past six years. In truth I have found it much more difficult to come back after a period of several days doing “just a tiny bit extra” than from a single day of “quite a bit extra”.
Understanding how these activity patterns work would also be useful, but I can’t seem to suggest a mechanism right now. It “feels” like there is something critical that gets depleted, and I just need to wait (and rest) until is gets restored.

Ooops… long post dumping a whole load of thoughts… hope it’s not too off topic. But maybe as the first of a load of “dumb ideas” it might make someone more knowledgeable than me think “Ah ha!”….
