The reason I wrote my long response was because you said exercise was painful. Sure, if you overdo it, it can be painful to anyone. But it's not supposed to painful. Uncomfortable sure, tiring sometimes yes.

But not painful. Afterward you should feel alert and relaxed. And in reasonable amounts it should feel like it is increasing what you can get done. Usually anyway.

If not, something is wrong. Hopefully something that can be treated.

Good luck to you! Health can be very tricky. In so many ways health and wellness is still in the dark ages. So many incomplete models and misinformation. I've been there and feel bad for anyone else bewildered because they don't fit into mainstream ideas of how their bodies are supposed to work.
