I can relate to morning and evening body pain, regardless of exercise or no exercise.
I have ongoing fatigue, but not all the time. I do sleep a lot, and honor the fact that I am tired. I don't fight it.
My symptoms rotate, and include brain fog, balance, and an annoying wet cough that's been treated and examined. Still there, but not as prevalent.
This has shifted my lifestyle, 2 years now, and I'm going with the flow of it all. I'm 78 and not giving up...things are just different.
I wish you well.
