Such reactions could be common, but people:

1) walk around clueless/don't know their bodies

2) don't report issues "How will that help me?"

I’m not sure I understand what you’re saying. How do those two points connect here?

If people don't report/just assume their Dr filed the report, issues go unreported.

I suspect this is largely the case in USA at minimum.
