I guess I'm talking two things here.
Wow, thanks for going into such detail!
in the 80's or 90's, I joined support groups and went to workshops/medical presentations on the condition. That's where I learned about knotting of the muscles, their lack of efficient use of oxygen and de-conditioning from lack of use.
I wouldn't think that much of what they thought in the 80s/90s is still relevant, from what people and the criteria development says, but I agree what you list are definitely things that still apply today.
It's interesting you describe muscle inefficiency as "problems unleashing their strength"; a very apt way of putting it. Can you elaborate on that?
Glad to... Attempting a deeper think about the connections....
The unleashing works on-off and is an energy & stiffness issue.
When "on", my muscle strength can be there for a varying time (from always 30 seconds to occasionally 2h), fully to fairly fully. Then "the brakes" slowly crunch in. - Similar my fine motor skill muscles, but semi-independently of the big muscles. Even more so social interaction via body and emotional muscle energy and the energy biochemistry behind it.
All surprising to others and myself to see that switch off, takes getting used to.
Of the 15 fatigue types I've identified, I call this "quick exhaustibility". Doesn't seem to have too much to do with stamina, cos since the 3rd jab I can use "slower energy" much longer whilst I'd lost the "fast energy" completely for a long time.
The brakes can be temporarily partly suspended / delayed by eustress and Chinese acupuncture increasing cortisol (and since the jabs histamine). But these are only only a mask, cos the backlashes are severe if I use that energy / lack of stiffness. Better was whole body cryotherapy, but also varying and not controllable, only manageable. Helpful is always cold showering.
But the fact that I can "carry on where I left off" with what I can then do shows that my muscles haven't become weaker in the meantime, no sore muscles. Perhaps partly because I'd got very fit in the 10 years before fibro and still move as much as I can under or stretching the limit.
Backlashes are 'only' a severe Ache, feeling ill, partly a little nauseous.
All that's improved with (V)LDN, it's doubled (10 to >20%) and stabilized my energy and decreased backlashes. But it's still an energy "window" - one minute i can charge up the staircase or cycle pretty fast, next minute i'm toppling over, have difficult standing and walking, cos I've lost control. Working with moderate energy in the garden I can do for hours, going to my shops or walking only 30' incl. there and back.
So what do I make of these "problems unleashing my strength"?
Several things that help point to my neurotransmitters askew - GABA to serotonin, reducing histamine to histamine, reducing stress to cortisol and vagus.
Cold showering helping to these and pro-inflammatory cytokines. And my local pains seem to mainly be tendin
itis esp. varying around all joints,
Could tendinitis be connected with stiffness and energy? All inflammatory?
Maybe a underlying
chronic inflammation (nerves, tendons and askew neurotransmitters) that jumps above a certain limit (switches on and off) by a trigger, similar to what you say next:
The reason I wondered about the fibromyalgia flareup as a result of the flu and consequent effect on the muscles is because of the involvement of that system in both conditons. ... nerve endings of the muscles ... muscle/neurological aftereffects of flu .... muscle weakness, balance and other neurological problems. So you have a preexisting condition and a stimulus that, in part, targets the muscles.
Ah, I get it. Reminds me of my swine flu 2011 praps triggering the onset of fibro, cos it was in that decade that I got "Ache flares". Nerve endings me too, but no directly neurological problems, and muscle weakness only in the energy sense.
Combination definitely well possible, so best to try to work on both bits.
protein in the muscles to help fight the flu, which... variable - the immune system.
Definitely, jab-triggered MCAS has "trebled" my fibro energy problems (from 30% down to 10%) - cytokines and many more things fit to both...
However, she could accurately determine through examination, the muscle groups that were weaker than others, and I'm grateful for the exercises she gave me for that.
Yep, important is that it works. Strengthening exercises for my wrists / underarms might be my weakest muscle area, I have various gadgets for that.
