When you have run for a while, you get a pretty good feel of what kind of pain / discomfort you can push through, and what kind of pain / discomfort is actually harmful.
I suspect that the original poster has a better sense of these factors, for their own body, than you do and is much more suited to make these decisions.
As someone who has been running a lot for past 30 years, I respectfully disagree. This is objectively a bad idea, no matter what the "factors" or "sense of" these factors is, or what the runner's subjective situation is.
No experience with a stress fracture of my leg and running. But I know when I had the flu and did a slow easy 1 mile run I felt much better after than before. Same thing happened with Covid.
