BBC article:Long Fatigue: The exhaustion that lingers after an infection

Before long Covid there was post-viral fatigue – a mysterious set of illnesses caused by other infections. Now scientists are starting to unravel its secrets.

Keller says that this research is also helping to identify subgroups of people who seem to be more at risk of post-viral fatigue. She believes that people who already have underlying muscle or nerve tension due to lifestyle habits, chronic injuries or surgeries could be more vulnerable because these underlying factors will already be inhibiting oxygen delivery around the body.

"We've found that tension from frequent or prolonged sitting, or in the muscles of the neck, chest and shoulders due to excessive screen time, surfing on cell phones and low strength and endurance of the core muscles that support correct spinal alignment may be a contributing factor," she says. "Injuries or surgeries that cause scarring of the connective tissue such as C-section or breast reduction, may also contribute to this tension."

Putrino says it is vital that we get better at identifying the precise factors which can cause people to end up in a state of prolonged fatigue, as this will enable the development of better diagnostics and ultimately more targeted treatments aimed at various subgroups of individuals.

"There are many drivers, and it's naive to think that a single drug or a single intervention will address everything," Putrino says. "But as long as we're methodical in investigating potential target drugs, and understanding why they don't work in different people, then we stand a chance of getting more sophisticated combination drug trials within the next 12 to 24 months. That could lead to some real hope for people living with these infection-associated chronic conditions," he says.

This is a BBC article: I thought I’d highlight that as it probably makes it more noteworthy.

 

Pretty weak article overall, though it gets some details correct, but they described pacing as literally GET:

The linked reference is this review, which includes a mix of studies that also conflate pacing with GET, and misunderstands that pacing is not a treatment, an intervention, or anything of the kind. I think the review was overall not bad and concludes that GET is not useful, but it causes confusion by the mix-up of pacing with GET despite being literal opposites.

Whether you look back 1 year, 5 years, 20 years, 50 years, a century, a millennia. It's all the same. Nothing seems to ever be learned here, everything is completely stuck in place. Incredibly frustrating when your entire life depends on doing better here, and just never seeing it. Any time there's some bits that are correct, there are also many parts that are wrong, or even comically and ineptly irrelevant.
