fibromyalgia does not actually cause damage to the muscles - ALS does . This is hard to understand this when you have extreme pain in the arm muscle. But a number of medical conditions produce "referred" pain
Yes, definitely true in that comparison. My muscles are still in perfect shape. I can always do 20(-30) quick pushups and when using T4 recently, the other day for the first time since fibro I could even manage 2 pull-ups in a row. However why the focus on muscle tissue? My hunch is the injury is on something like a cellular level that is as yet not measurable - associated with chemical imbalances not just in the brain, but all nerves, the muscles, the gut, the mast cells, the whole body.
there are many suggestions on the cause for fibromyalgia from lack of rem sleep , diet etc which all basically come down to a chemical imbalance in the brain that in theory effects the central pain system -
I wouldn't ever have counted these as separate causes, they are triggers, and like you say they would be a part of other hypotheses, like the CSS one.
What I'm referring to as cause hypotheses are 2) autoimmune (e.g. Goebel et al. 2021), 3) SFN, 4) AV-shunt, 5, neuroendocrine, 6) mitochondria, 7) underlying issues, praps varying (chronification of pain, sleep disorder (like you say), low GABA, other diseases like SPD, MCAS (mast cells), 8) genes,
which I've listed
here along with a load of biomarkers, which no one would claim to be a cause, just sign / association.
What do you think about these hypotheses?
I can see sleep & diet associated with chemical imbalance, but not necessarily (just) the CNS. It can just as well substantiate the other cause hypotheses or something completely different.
I can fully agree with a chemical imbalances perhaps being a crucial part of fibro though - that would also fit to my symptoms, as opposed to central sensitization, at least. These are all actually associations, no proven causation visible.
I have greatly improved local pains and sleep, but that doesn't improve my energy or Ache = my fibro.
If I push thru the Ache my wife sees my body deteriorating.
The flu doesn't injure our muscles or nerves either, but that doesn't make it necessary to invent a new pain type. Just flu inflammation is measurable, what's behind this hasn't yet been found, doesn't mean there is nothing tho.
this is where most of the research is looking at currently and at least to me it fairly logical I have no muscle loss no
In the yearly Italian summaries "Fibromyalgia - one year in research" the studies they described 2022 regarding pain neurophysiology were not in the context of
causes, but of
associations (like obesity, glucose interolance and CVD). (Liu, Sandström, Ellingsen, Lee, Müller and Raffaeli)
true stress etc can increase the pain but then stress upsets the chemical balance in the brain thus could upset the central nervous system - stress also increases my essential tremor but stress does not cause it. Diet can upset the chemical balance in the brain but diet does not cause either conditions .
I agree, stress and diet may be triggers for some. (They don't seem to be for me.)
Chemical imbalance: I agree all the way. CNS / CSS? Can't see even partially conclusive evidence.
There is a lot of good research being done on fibromyalgia at present - these may come up with a cure or better
Well the 900 pubmed articles every year show that researchers are interested. But it's hardly getting anywhere. In the last 3-4 years, the "autoimmune" study in 2021 was the only one managing to show something 'bigger'. However it was only small, and mainly mice. There's still too many basics missing.
