I don’t trust doctors at all. Most doctors get eight minutes to diagnose and treat a patient. I have been misdiagnosed more times than not, because doctors just don’t care. All they care about is getting the bill paid. $200 for 8 minutes and a misdiagnosis is a waste of my money and time.
I’m so sorry about your grandmother. I can imagine how frustrating it is.
She was well up there in years by any standard, but they were pretty irresponsible to have performed the particularly invasive procedure on a woman her age. She developed - no surprise - an infection that killed her.
But hey... fetuses and geriatrics are worth less nowadays.
