This is a fascinating discussion. I like how we are debating fatigue, as I think this is the point where I lost my dr.
I have satisfied the ICC criteria for decades, but I don't have any "fatigue".
I have muscle weakness and cognitive dysfunction.
So now I have to ask, do you have true muscle weakness? I told my dr I had muscle weakness, and he had me squeeze his hand. He said my muscles were fine as I have a good grip and can lift a heavy box. Once. But I feel extremely weak compared to what I used to be. My muscles fatigue far quicker than they used to, although I’m nowhere near as sick as I used to be. Gingergirl used to not be able to open a water bottle or the door. I would define that as muscle weakness, but I’m never sure.
With sickness type fatigue, mine is minimal now. With muscle fatigue, it’s horrible now. I used to be able to hike and bike and be very physically active on weekends. I was horribly sick all week though. Now I can barely lift a finger and rarely leave the house on weekends or my body and brain doesn’t function well.
So I believe we have three types of fatigue. Flue fatigue, I worked out far too hard at the gym muscle fatigue, and brain fatigue.
Circadian rhythm disruptions are a well-known symptom of ME/CFS, and there is no easy solution, unfortunately. It is a subject that has been talked about on these forums quite a bit.
But we are talking this thread off topic.
But is it off topic? It’s part of the ICC and I don’t see it any different from debating fatigue.
