updating you on todays symptoms with my CFS, autonomic issues et al that we have talked about before. Today. I have.. what I call... "taken the piss". I had to do a physical task today, take my car to the garage to get it looked over. Involves me getting ready. Getting out of the house. Social masking. Getting home. I was very tired on getting home. But. Did *not* retreat to a resting state / position. My friend asked to play some games. Which I did so. I was very aware this was Not Good. And pushing past warnings, and what I know to be very punishing terrain. Stayed up as long as I could - nausea dramatically increased, exhaustion, brain fog, muscle pains. Pushed to the last moment. Couldn't even eat at that point, collapsed into bed. Couldn't immediately sleep... weirdly... too exhausted to immediately sleep.
Then slept. During sleep could feel I felt "awful", horrible heavy exhuastion everywhere and a lot of muscle pain.
Woke up 4 hours later feeling utterly terrible. Heavy limbs. Exhaustion. And. All over sharp pains in all major muscles. Lats, obliques, pectorals, shoulders, thighs, calves. Like bad bruises that are being pressed on - this is a symptom I sometimes get. All over muscle pain. Bad enough to steal breath away.
Comments ?

Yes. What you describe is textbook post-exertional malaise (PEM) layered on top of autonomic overdrive, and the sequence you outline is actually very diagnostically clean — unpleasantly so.

Let me break this down in a way that matches what you felt, not just labels.

What happened (mechanistically)

1. You spent your limited “daily envelope” twice

The garage trip alone already contained multiple high-cost elements for someone with CFS/autonomic dysfunction:

upright posture + walking
cognitive sequencing (getting ready, travel, logistics)
sensory load
social masking (this is not trivial — it’s metabolically expensive)

You got home already depleted. That “very tired” state was the warning light.

2. You overrode the warning system

When you chose to game:

You suppressed interoceptive signals (“this is not good”)
You added cognitive load + emotional engagement
You stayed upright and alert instead of down-regulating

This forces the body to compensate using stress systems (sympathetic nervous system, cortisol, adrenaline).

You didn’t “power through” —
you borrowed energy that doesn’t exist.

CFS bodies will let you do this once — and then invoice you later with interest.

3. The nausea spike + inability to eat

That’s a classic autonomic red flag:

Blood flow diverted away from the gut
Vagal tone suppressed
Gastric emptying impaired

At that point, your system was no longer choosing — it was failing to regulate.

4. “Too exhausted to sleep”

This paradox is important and often misunderstood.

You were:

physiologically exhausted
but neurologically hyper-aroused

Think:

Battery empty, engine redlining

This is sympathetic overactivation without energy substrate — a horrible state.

5. Sleep felt bad

You didn’t get restorative sleep.
You got collapse sleep.

That “heavy, awful, painful” sensation during sleep is your nervous system being unable to downshift properly — incomplete parasympathetic recovery.

6. 4 hours later: severe diffuse muscle pain

This is one of the most characteristic (and cruel) PEM signatures.

The pain you describe —

“like bad bruises being pressed on”
stealing breath away

Strongly suggests:

Delayed inflammatory response
Impaired oxygen delivery / microcirculatory dysfunction
Metabolic by-product accumulation (lactate, cytokines)
Central pain sensitisation

Importantly:
This is not muscle damage from exertion.
It’s systemic dysregulation.

That’s why:

it’s widespread
hits large muscle groups
feels disproportionate
arrives delayed

Why this happens after the activity, not during

CFS/ME is not an exertion intolerance — it’s a recovery failure disorder.

You don’t fail while doing the thing.
You fail when the system tries to re-establish equilibrium and can’t.

That’s why PEM:

is delayed
is non-linear
feels like poisoning, not fatigue

The hard truth (said gently)

Your body gave you accurate warnings.
You recognised them correctly.
You consciously crossed the boundary anyway.

That’s not a moral failure — it’s a human one.
But your system does not negotiate.

CFS/autonomic illness is brutally literal:

Input exceeded capacity → collapse follows.

What matters now (practical, not preachy)

Short term (next 24–72h)

Radical rest — not “light activity”, not distraction-rest
Horizontal as much as possible
Minimal cognitive and sensory input
Eat only what is easiest tolerated
Hydration + electrolytes if you can tolerate them

This phase is about damage control, not recovery.

Medium term (the real lesson)

You’ve just re-mapped, very precisely, where one of your true boundaries is.

Two key takeaways:

Social + cognitive load after physical exertion is a multiplier, not an add-on
The moment nausea ramps and eating becomes hard, the day is already over

That point is not “nearly too much”.
It is past the line.

One important reframing (to reduce guilt)

This wasn’t you being reckless.
This was you being human in an inhuman constraint system.

But now you have fresh, embodied data — not theory.

And that data says:

“When I override early fatigue, I don’t lose a bit of tomorrow — I lose days.”

If you want, next time we can:

map your early abort signals more precisely
distinguish recoverable tiredness vs non-recoverable warning
build a decision rule that removes willpower from the equation

For now:
What you’re feeling makes sense.
It is real.
And it will ease — slowly — if you stop feeding the spiral.

I’m here with you in it.

so, instinctively it does feel to me at times like a system inflammatory response - because *everything* squeals all over, its not just a point of focus, its the whole system. and its like a complete dip in a pool. why does this inflammation spike happen ? why is the body responding in this way to over exertion ?

Your instinct is very good here — and importantly, you’re not just using “inflammation” as a vague catch-all. What you’re describing really does behave like a system-wide inflammatory / immune-metabolic response, not a local injury signal.

I’ll answer this in layers, from what we think is happening, to why the body would do something so maladaptive, to why it feels so global and brutal.

Short answer (to orient you)

In CFS/ME (especially with autonomic dysfunction), exertion triggers an inappropriate immune-metabolic alarm response, as if the body believes:

“We are under systemic threat — initiate sickness response.”

That response includes:

cytokine release
altered energy metabolism
pain sensitisation
autonomic shutdown / re-routing

It is not proportional to tissue damage.
It is a signalling error — but a consistent, patterned one.

1. Why exertion triggers inflammation at all

In healthy people, exertion causes:

minor muscle micro-stress
transient immune activation
then rapid resolution + anti-inflammatory rebound

In CFS/ME, several things appear to go wrong simultaneously:

A. Metabolic stress without reserve

Your cells struggle to meet energy demand (mitochondrial / metabolic inefficiency).

That creates:

oxidative stress
abnormal metabolite buildup
danger signals (DAMPs)

These look to the immune system like injury or infection — even though they aren’t.

B. Immune system misinterprets the signal

Instead of:

“Localized, manageable exertion stress”

The immune system reads:

“Systemic threat: act globally”

So it releases cytokines such as:

IL-6
TNF-α
IL-1β

These are the same molecules involved in:

flu
COVID
sepsis-adjacent states

Hence the sickness feeling.

2. Why it’s systemic, not local

This is the key to your “dip in a pool” analogy — and you’re spot on.

Cytokines are broadcast signals.
They don’t stay in one muscle group.

Once released:

they circulate
they act on brain, muscles, gut, vasculature

That’s why:

everything hurts
cognition collapses
nausea appears
limbs feel heavy
pain feels diffuse and bruised

This is not “lots of small injuries”.
It’s one big systemic message.

3. Why the pain feels so intense and weird

Two important amplifiers are likely involved:

A. Central sensitisation

Inflammatory cytokines:

lower pain thresholds
amplify sensory signals
make normally neutral sensations hurt

So muscles aren’t damaged —
they’re being perceived through an inflamed nervous system.

B. Microcirculatory dysfunction

There’s growing evidence of:

impaired oxygen delivery
abnormal blood flow regulation

During and after exertion:

tissues become relatively hypoxic
metabolites accumulate
pain receptors fire disproportionately

This produces:

deep, bruised, squeezing pain
not sharp injury pain.

4. Why the response is delayed

This is another big clue that it’s immune-mediated.

Immune cascades:

take hours to peak
don’t align with activity timing

So:

you push
you seem “okay”
then the cytokine wave crests later

That delayed crash is almost diagnostic of PEM.

5. But why would the body do this?

This is the hardest question — and the most important.

The leading hypothesis:

Your system is stuck in a pathological threat-response loop.

Originally (often after infection, trauma, or prolonged stress):

immune and autonomic systems became tightly coupled
exertion became associated with danger

Now:

exertion = threat
threat = sickness response

This may have been protective once — forcing rest during illness —
but it never fully reset.

So now your body treats normal exertion like:

“Stop everything. Shut it all down.”

6. Why resting early prevents the spike

If you stop early enough:

metabolic stress stays below the immune alarm threshold
cytokines are not massively released
recovery remains possible

Once you cross that line:

the immune cascade is self-propagating
rest after does not abort it — only shortens it

That’s why “pushing through” is so punishing.

7. Why this feels qualitatively different from normal tiredness

Because it is.

Normal fatigue:

local
proportional
resolves with rest

PEM:

systemic
delayed
inflammatory
feels like poisoning

Your language for it is actually very accurate.

A grounding statement (because this matters)

This is not:

deconditioning
weakness
anxiety
lack of resilience

It is a biological overreaction to metabolic stress.

You didn’t imagine it.
You didn’t “decide” it.
Your body did it to you.

If you want, next we can:

map which exertions most reliably trigger the inflammatory threshold
discuss why cognitive/social effort can provoke the same response
talk about why repeated crashes worsen baseline over time

But for now:
Your interpretation is sound.
Your body isn’t broken — it’s misfiring.

And understanding that helps you stop blaming yourself for the alarm going off.

if the system has become conditioned to respond badly to exertion, is it possible to de-program this and reverse the conditioning, or is it stuck like that

This is the right question — and it deserves a precise, non-ideological answer, not the false binaries you often see (“it’s all reversible” vs “you’re stuck forever”).

The honest answer is:

For some people, parts of the response can be de-conditioned or dampened.
For others, it can be managed but not fully erased.
And for many, it depends on which layers of the system are driving it.

Let’s unpack that carefully.

First: an important correction to the word “conditioning”

What you’re describing is not conditioning in the behavioural sense (like Pavlovian learning alone).

It is better thought of as a pathologically stabilised physiological state involving:

immune signalling
autonomic regulation
energy metabolism
central nervous system threat processing

There may be a learned/threat-association component —
but it is anchored in biology, not belief.

That distinction matters, because it explains why:

“just push a bit more” fails
CBT/GET failed many patients
willpower does nothing
reassurance doesn’t turn it off

So: is it theoretically reversible?

Yes — in principle — but not trivially, and not universally.

Think of it like this:

The system has settled into a maladaptive attractor state.

Those states can sometimes be exited —
but only if you stop reinforcing the loop and give the system a viable alternative equilibrium.

The system has multiple layers — and they do not all reset equally

1. Autonomic layer (ANS)

This is the most plastic layer.

Sympathetic overdominance
Poor vagal tone
Abnormal baroreflexes

These can improve in many people over time if:

crashes are avoided
baseline stabilises
stress signals reduce

This is why some people see improvement with:

aggressive pacing
time
autonomic-friendly routines

But improvement here does not guarantee PEM resolution.

2. Immune / inflammatory signalling

This is less plastic, but not frozen.

Low-grade immune activation can:

dampen with prolonged stability
reduce after long periods without crashes
sometimes improve years later

However:

repeated PEM episodes re-sensitise this system
crashes train it to fire faster and harder

This is why boom-and-bust makes the illness more entrenched.

3. Metabolic / cellular layer

This is the hardest part.

If there are:

persistent mitochondrial inefficiencies
redox imbalance
oxygen utilisation problems

Then no amount of “re-training” will make exertion safe beyond a certain ceiling.

You can only work within that envelope.

4. Central threat / prediction layer

This is where the word conditioning partially applies.

The brain predicts:

“Exertion → danger → sickness response”

Those predictions can soften if:

exertion stays consistently below the immune trigger threshold
safety is repeatedly confirmed without crashes

But — and this is critical —
this only works if the biology cooperates.

If you cross the line and trigger PEM:

the prediction is reinforced
the alarm becomes more sensitive

Why “graded exercise” failed (and harmed people)

Because it assumed:

The system is falsely predicting danger.

In many patients, the system is actually:

Correctly predicting metabolic collapse.

So graded exposure:

repeatedly triggered immune cascades
worsened baseline
entrenched the attractor state

That’s not deconditioning — that’s re-injury.

The only viable path (when improvement happens)

People who genuinely improve tend to follow an unsexy, slow, boring pattern:

Radical respect for early warning signs
- stopping before nausea, pain, fog
- not after
Long periods of stability
- weeks to months without PEM
- not “slightly smaller crashes”
Very cautious expansion
- only when baseline feels solid
- never testing limits “to see”
Immediate retreat at first warning
- zero heroics
- no social obligation overrides

This is not “pushing the boundary”.
It’s waiting for the boundary to move — if it ever does.

The hard truth (said clearly)

Some systems do not fully reset.

In those cases:

the goal becomes containment, not cure
quality of life comes from precision, not endurance
wisdom is learning the shape of the box, not trying to escape it

That is not defeat.
It is adaptation to a real constraint.

A reframing that may help

You’re not asking:

“How do I become normal again?”

You’re asking:

“Is this system capable of learning safety again — or is it locked?”

The answer is:

partially,
slowly,
only if it stops being injured,
and only within its biological limits.

If you want, next we can:

distinguish reversible sensitisation vs hard ceiling signs
identify which early signals are “abort now” vs “yellow flags”
talk honestly about whether improvement or long-term management is the more realistic target for you

But you’re asking the right question — and you’re asking it without magical thinking. That already puts you ahead of most of the system that’s supposed to help you.

I see. So. To oversimplify, in summary. Rest. Long. And properly. Avoid any stress. Avoid any crashes. You get your best chance of slowly improving the condition

Yes — that summary is essentially correct.

If I strip it down to its least misleading oversimplification, it’s this:

Stability first.
No crashes.
For a long time.
Then see what moves.

That is not a guarantee of recovery — but it is the only known way to give the system any chance of softening rather than hardening.

Let me tighten the framing so it’s usable, not just true.

What “rest” actually means (because this is where people get trapped)

Rest ≠ inactivity alone

Rest means:

physiological down-regulation
not provoking immune or autonomic alarms

You can be “inactive” and still stressing the system via:

cognitive effort
emotional load
vigilance
social masking
sensory overload

So “proper rest” is about signal quieting, not just lying down.

What “avoid stress” really means

This is not about “relax more” or mindset.

It means avoiding:

exertion that pushes you into warning territory
novelty-heavy tasks
obligation-driven overreach
“just this once” decisions

Stress, here, is anything that forces compensation.

If you feel you’re managing the activity rather than being carried by it, it’s probably too much.

What “avoid crashes” actually buys you

Every crash:

re-triggers immune cascades
sharpens the alarm
pushes the baseline down or stalls recovery

Every non-crash day:

lets inflammation settle
allows autonomic tone to rebalance
preserves the possibility of improvement

Think in weeks without PEM, not days.

The uncomfortable middle truth

You don’t improve by:

testing limits
proving resilience
seeing how far you can go

You improve by:

not needing resilience at all

That feels passive.
It isn’t. It’s disciplined.

The realistic best-case trajectory

If improvement happens, it usually looks like:

fewer symptoms at the same activity level
slightly larger envelope without noticing
less severe crashes if they happen

Not:

sudden tolerance
linear gains
“I can push now”

It’s subtle and easy to miss unless you’re careful.

One rule that helps many people (brutal but effective)

If you are deciding whether you can afford to do something — you already can’t.

Safe activity feels boring and unremarkable.
Dangerous activity feels engaging but costly later.

Final grounding note

This approach is not:

surrender
laziness
fear-based

It’s biological pragmatism.

You’re working with a system that punishes error —
so you reduce error rate, not try to overpower it.

And yes:

Long, proper rest + no crashes = your best chance.

Not a promise.
But the only rational strategy we currently have.

If you want, next we can:

define what “long” realistically means
talk about how to live inside this constraint without losing your mind
or build a concrete “abort early” decision framework so you don’t have to reason in the moment

Just say where you want to go next.

hmm. gosh. I think I need this emblazened on a big sign to hang in my house - "If you are deciding whether you can afford to do something — you already can’t."

Yeah. That line lands hard because it’s true in the way gravity is true, not in a motivational-poster way.

It works precisely because it removes negotiation.

When you’re ill like this, the danger isn’t ignorance — it’s bargaining:

“Maybe just a bit…”
“I’ll rest after…”
“This one matters…”

That sentence short-circuits the whole internal debate.

Why it’s such a powerful rule

Because it converts a fuzzy internal state into a binary external rule.

Your system is bad at:

estimating remaining capacity
predicting delayed consequences
resisting social/emotional pressure in the moment

So you offload the decision to logic ahead of time.

No willpower.
No judgement.
No self-reproach.

Just:

Decision detected → answer is no.

The deeper version of the rule (worth keeping in mind)

What it’s really saying is:

Safe activity does not require cost–benefit analysis.
If analysis is happening, compensation is already happening.

Healthy people don’t ask:

“Can I afford to walk upstairs?”
“Can I afford to talk to a friend?”

When you ask that question, it means your body already knows the answer —
your mind is just trying to override it.

A companion line that pairs well with it

Some people find this helps too:

“If it matters, it must fit inside my energy — not borrow from tomorrow.”

It reframes “important things” as needing better timing, not heroic sacrifice.

If you do make the sign (seriously, not joking)

Put it:

where you usually decide to “just do one more thing”
near your PC / console / phone
somewhere it interrupts momentum

Because the most dangerous moment is not when you’re exhausted —
it’s when you’re almost exhausted and still functional.

One last, gentle truth

This rule isn’t about shrinking your life.

It’s about protecting the future version of you from the present version who still hopes, still wants, still tries.

That’s not weakness.
That’s stewardship.

If you want, I can help you:

refine this into a small personal “ruleset”
or turn it into a few short mantras that cover the most common traps you fall into

But honestly — if you remember just that one line, it will save you a lot of pain.

I can see the deep wisdom in it. I understand its cutting off that bargaining step before it begins. and it absolutely resonates. I can see I do that. a lot.

Yes — and the fact that you can see yourself doing it is the important bit. Most people never quite catch the mechanism in the act.

What you’re noticing isn’t a personal flaw. It’s a perfectly rational behaviour in a system that sometimes lets you get away with things — until it doesn’t. Intermittent reinforcement is the most powerful trainer there is.

What that bargaining really is

When the thought appears —

“Maybe I can afford this…”

That’s not optimism.
That’s the last intact control loop trying to preserve a normal life.

It’s the same loop that:

wants connection
wants agency
wants to not be ruled by illness

So it negotiates.

The problem is:
it is negotiating with a system that invoices later, and invoices brutally.

Why this hits people like you especially hard

You are:

perceptive
analytical
used to managing complexity
accustomed to “stretching systems” successfully

That skillset usually works in life.

Here, it backfires.

You can reason your way past warning signs —
but your body doesn’t accept arguments.

So the bargaining voice sounds reasonable, not reckless.

The cruel paradox

The more intelligent and conscientious someone is, the more likely they are to:

justify “just this once”
create elaborate exception cases
carry responsibility longer than they should

Less reflective people sometimes do better simply because they stop earlier without explanation.

What the rule really gives you

It’s not restraint.
It’s permission.

Permission to:

stop without explaining
not optimise
not prove anything
not be fair to circumstances

The rule says:

“You don’t have to be right. You just have to be safe.”

A subtle shift that helps reduce guilt

Instead of thinking:

“I chose not to do X.”

Think:

“X didn’t fit inside today’s envelope.”

No blame.
No virtue.
Just geometry.

The quiet victory most people miss

Every time you:

notice the bargaining
stop at that moment
don’t test it

You’ve just:

prevented an immune cascade
preserved baseline
taught your nervous system something new

Nothing dramatic happens.
Which is the point.

One last line to sit with (no action required)

“I don’t need to win this moment. I need to survive the pattern.”

You’re not giving up.
You’re learning where leverage actually is.

And you’re right — seeing the bargaining is the beginning of wisdom here, not the end.
