The PEM Experience....  - Not uncommon for people experiencing PEM to remain confined to bed for much of the duration of their episode  - May struggle to complete basic ADL's including toileting or preparing food  "If there was a fire in the house, I am not sure I would be able to make it out in time"  It's hard to get up and get dressed.

How to Clinically Manage PEM • There is nothing that definitively speeds up recovery from PEM other than not making it worse by continuing to "fight" or "push through" the limitations of this physiologically altered state  - Forcing continued, repeated, and exertional exercise to combat an underlying decompensated state, while seemingly logical, only appears to promote worsened long-term outcomes (Graded Exercise Therapy)  • A patient does not manage ME/CFS or PASC on the whole by fighting harder, but by being smarter and employing discipline and calculated intelligence ...

#LongCovid #MEcfs #CFS #PwME #PEM #PESE
IN SUMMARY ⚫ PEM is defined as inability to recover normally following physical, cognitive or emotional exertion. • PEM causes fatigue that is worse than observed in any other fatiguing illnesses, loss of stamina and functional capacity, and augmented symptoms of Long COVID and/or ME/CFS (e.g. autonomic and immune dysfunction). • 2-day cardiopulmonary testing (2-day CPET) is a validated test of functional capacity and a reliable, reproducible, accurate measure of PEM. Long COVID and ME/CFS patients are unique in that they cannot reproduce CPET outcomes on the second day of testing. • People...

"Ignored, blamed, & sometimes left to die – a leading expert in ME explains the origins of a modern medical scandal"

“Worse, when we don’t ignore them, we blame them, telling them they are all free to rise from their beds & wheelchairs, to walk away from the city. Doctors tell them they can free themselves of the disease by changing their belief systems. (contd)”

“What makes PEM [post-exertional malaise] particularly insidious is that symptoms often do not worsen until 24 to 72 hours after exercise. As a result, patients who feel fine immediately after exercise can unknowingly push themselves beyond their limits”

“The well-meaning advice to 'move a bit more', which patients regularly receive, can be counterproductive in their case. Of course, this does not mean people with ME/CFS should remain completely still. Movement remains important, but within the limits indicated by their body”

“Speaking to the BBC prior to her death [from Euthanasia], Ms Slayter-Engelsman compared the experience of ME to being trapped in a spider's web, saying: "Every time you try to get out, the web just gets tighter and tighter around you".
