Hi @bla1958
I am trying to navigate systemic problems that include some of what you are bringing up, so I am not sure I know much. I am trying to understand what possibilities are as far as what can be wrong and what could help. Something beyond what we know, right?

I did find something recent that sorta walks through how non cardiac chest pain is addressed. I notice the authors are from Mayo Clinic. It looks like PPIs are the first go-to but maybe not the only one. Have your doctors recommended anything else to try?

@kirbylogan maybe this could help you on your quest as well. 😀
