My mom had a sudden acute glaucoma, we didn't knew it was glaucoma yet, and she was sent to hospital.
Same shit, wealth extraction, no proper care.
We begged help from her usual eye doctor, sent to him photos of her eyes that had obvious glaucoma for someone that know what glaucoma is, and he just replied she is fine.
Eventually we found on our own she had glaucoma and transferred her to a university, where students wanting to learn treated her, or tried, since they couldn't do anything without permission from licensed medics, and the medics and their teacher all were for "some reason" unexpecteadly absent.
She is getting better now, but got some permanent damage that wouldn't have happened if someone bothered to look at her.
In the initial hospital she went to, nurses told me they asked for a medical specialist to come and see her, that I could rest easy and they would fix the issue. Later on, my father asked one of the hospital administrators that is his friend, and he checked the records, and found out the nurses lied.
If that is the treatment you get when you are paying and when hospital administator is your friend, imagine when you are poor...
EDIT: in general, I don't trust medics, almost all medics I know are liars, scam artists or butchers, I have a list of medical malpractice on people I know bigger than the list of stuff fixed, including deaths caused by medical malpractice.
My personal issues are mostly self-treated, with me going to medics only because the law obliges me to to get the needed prescriptions.
My wife is pregnant, and her medics told us a lot of suspicious stuff, I hired a doula and some nurses out of my own pocket, a team that helped with childbirth of a friend of my wife, and asked them about all sketchy stuff the medic said, and they gave me the details, including the science, to prove to me the medic is actually trying to scam my wife into having a privately paid caesarean section in a expensive hospital. And indeed when I asked the medic later how much he expects the birthing to cost us, he quoted us a totally eye-watering figure and said our health insurance wouldn't cover it (a lie, we checked this already).
EDIT2: how to be a butcher: insist a guy has cancer, when everyone insists he doesn't have cancer, then have a exploratory surgery to find his cancer and kill him on the sugery table, then you say "oops, he didn't had cancer after all!"
