Of course there are problems, waiting lists, lack of funding. But damn, it's good and (mostly) free. I feel lucky.
Perhaps there are regional differences, but in my city, it's really good.
I think variance is big and individual examples are useless unless you have the exact same problem in the exact same locality as someone else. But I think it's safe to say that anything falling outside standardized diagnosis may not work out so great. I had to do my own research myself and beat a professor's (of medicine) prediction and amazed a few other doctors with "miracles", but I did not actually do anything special, just what I thought was kind of obvious after some research. When you fall into one of the many blind spots your experience will be bad, if you fall into one of the categories which are "standard" you'll probably be one of those people who are very satisfied by what the system provides.
One has to understand how doctors are trained and what the system they work in forces them to do (and what not to do). Once you understand that you may get more satisfaction. For example, doctors prefer treating immediate problems. If you come with a long and varied history, they don't have a time for that, and often they would not know what conclusions to draw anyway - the body is complex and even if they had a hunch, the more possibilities there are the harder it is to diagnose. Also, expectations of expectations: Doctors know (sometimes learned the hard way) that people expect miracles or at least solutions from them when in reality they themselves often don't know.
Finding the cause of a problem may take months or even years of commitment (in retrospect, after a diagnosis, it's always clear of course, "why didn't we think of that sooner"). Few patients have the resources, the patience(!) and will to slowly and iteratively work on a problem, especially when success is highly uncertain. I only solved the one I myself had because I took some very radical steps that set me back income-wise for a decade at least and cost me a few social connections. The majority of people would have gone with "placebos", symptom-covering "solutions" for immediate problems, instead of choosing the great uncertainty (and when I started it was very uncertain indeed and everybody advised me to be "reasonable" and not throw my life away to chase ghosts but listen to the doctors). If I was a doctor I would never treat someone like me - because it would be highly unlikely that the person would be as extreme as I was and give up so much of their current life for very uncertain future benefit. So what doctors offer also is a mirror of what patients expect and are willing to invest (and I don
't mean money, the time and effort under uncertainty is much harder to bear).
By the way, my tonsils disappeared by themselves! I went to nose and throat specialists a few times during the last decade because during my long recovery I had plenty of throat issues. At some point they wondered why my tonsils where so tiny, and during the last appointment last year or so I was asked when they had been removed - they weer gone. I never had surgery, and I'm sure I still had them a decade ago. No use asking, nobody knows what happened. They were definitely never removed (or the doctor three years ago would not still have found them to be unusually small, and the next one three years later that they were not there at all).
The experience of various family members at different stage of their life (we had to deal with childbirth, cancers, complex surgeries, broken bones, and simply old age, etc) and my experience in living in different countries. I am happy of my city hospital.
That's all pretty standard, all of those I'd trust most modern hospitals with. Yes there can be big differences, but at least all of those are part of the standard things modern medicine excels at. Anything ER, surgery, child birth. Cancer treatment is more variable but there's standards, they know what the problem is, they know what to do for diagnosis, and treatment is pretty standardized and most variance is how much they are willing to experiment with the latest (and most expensive) treatments.
Try having anything that is systemic and not easy to see (or invisible to any biomedical imaging). Each time you have a clear diagnosis for which doctors can go to their catalog of appropriate treatments you are lucky. Anything obviously and visibly broken (incl. by using imaging tech) is "the easy stuff".
Your satisfaction also depends on how willing you are to accept whatever the doctors tell you!
If I had accepted the verdict some ten years ago I would never have found that there actually was a relatively easy to identify and treatable cause for my issues. If I had accepted the endocrinologist's recommendation for surgery to remove the nodule in my thyroid, and part of the enlarged thyroid too, I would have had a happy surgery experience, because they are good at hat. But I didn't - and the nodule disappeared and the thyroid shrank back to normal to the great amazement of the endocrinologist.
I don't mean to criticize your assessment, I'm happy myself too - but I had to do all the heavy lifting myself, it's just that I know how to use "the system" and how to get what I want from it and not asking for things they are bad at delivering. If you always accept what they tell you psychologically you will be a satisfied customer and life is easy (even if the problems persist, but if you accept them as inevitable your mind learns to ignore them pretty well). If you don't know and never assume that things could be better you'll always give top-rates.
I was extremely satisfied (no exaggeration) and full of unshaken trust in all doctors for almost 40 years, and I had things like jaw surgery to correct an under-bite. I went into this surgery as if it was an appointment for a hair cut, they did not even give me anything to lower anxiety even though they had planned to - my trust was complete, and for things like surgery it still is. Only when I had a problem where there were symptoms but no known cause did I hit a wall and had a very rude awakening.
I looked it all up and read a lot online afterwards, his procedures were immaculate and complete including all the blood work he had ordered, beyond a normal checkup, left nothing left to ask for given the symptoms I had presented. His diagnoses was 100% correct and according to all guidelines in the modern medical world, whether you are in Europe or the US.
Except that nothing made sense.
He completely ignored when I told him that I had never in my life had so many issues as with the PPIs. He asked me to be patient, just a few more weeks and we could lower the dose. But in addition, I felt that 99.9% of all my problems were "unaccounted for" in that diagnosis, that it only was about one tiny issue, but I felt it was much more systemic and that the recommendations would do nothing whatsoever towards finding a solution. It was putting buckets under the leak instead of finding the leak in the roof and fixing it. But I found that it was perfectly normal not to look for the deeper explanation, the cause of problems such as I had had!
First thing I found after a few weeks was that I had a huge candida outbreak. The professor had ignored the symptoms, I found the description on some website that I thought was entirely bonkers and esoteric, which is why I ignored it at first. But after weeks of no solution, and it got worse, I went back to that website and checked other ones too. I thought, it must be candida! I got an oral anti-fungal (cheap, no recipe required) - and within 15 minutes I had confirmation that it was a fungal infection. I went to a doctor with the diagnosis and got it confirmed, and I even got systemic anti-fungals (fluconazole based), all of it with huge success.
HOWEVER - I soon learned that a fungal infection isn't a cause, it is itself only a symptom. The only thing I found that was a remote possibility was: heavy metal poisoning. I did a test, I searched for specialists, I had to go travel a few hundred kilometers to an environmental medicine doctor at a university clinic, he said I'm a gray area case and I must have something else but that I should start chelation. He never found anything else, and ALL problems I ever had slowly disappeared, including miracles such as the thyroid thing. The prediction about "PPIs forever"? I have not taken one since 5 weeks after the professors prediction and my gut health now is PERFECT, like I never knew it, not even in childhood.
Growing up as a child in East Germany we had lead pipes at home, but they had a thick layer of mineral build-up and even though I also heavily used DMSA, a prime chelator for lead, no significant amounts of lead ever showed up. Given that health came back - to levels not seen in decades - without us ever seeing much of lead, only mercury, I guess it must have been mostly mercury.
The only possible source is amalgam fillings in teeth, which I got in childhood in East Germany. I found a document that indicates that the kind of mixture they used there was different and was abandoned elsewhere long before, so that may be a contributing factor. Nevertheless, my jaw bones had lost their trabecular structure and were in a bad state in exactly the places where the amalgam fillings had been. This was found by the doctor who just wanted to do a regular injection into the buccal mucosa - and ended up deep inside the bone. Ooops, that's bad, he said. He injected DMPS, mercury chelator, and in the following months my jaw bones "came alive". In a positive sense. A year later he found the bone impenetrable everywhere he tried, it was penetrable by a simple needle without pressure in all four quadrants before that (I had had fillings in all quadrants, fortunately none very deep).
I also remembered that my East German dentist, after reunification asked me if she should replace some of the amalgam fillings with plastic fillings. I had no idea why and what and did not care, I always said "yes" to every suggestion a doctor ever made to me, I was completely unaware of any "amalgam controversy" until I had to do my desperate research of what was wrong with me. But now I remember that at exactly that time, just a year after I had started studying, I had suddenly and out of the blue developed severe, almost asthma-like allergy, had inexplicable problems in various joints, had terrible sleep issues, and a lot of other stuff. And I barely managed to pass the math classes (CS study) - I had always been a top math person and we had high-level math instruction at high-school (in year 3 of the CS study I discovered that the lecture was exactly about the same stuff that we had had in high-school from our over-achieving teacher). I had gotten "stupid", but I only realized it when everything cleared up under the chelation treatment and I've taken over 60 mostly STEM courses on Coursera and edX and now my brain works again. My dentist had removed the amalgam fillings with a normal drill and without any protection. When I did the research eight years ago even a fresh doctor in residency warned me not to have my remaining amalgam fillings removed - because of the danger of mercury being freed ("this is dangerous" was what she said), the drill creates vapor no matter how much water you use to cool it, and mercury vapor is the worst since it can penetrate all the surrounding tissues. When I had the remaining fillings removed it was done with special equipment and a chelating agent to wash the mouth after each removed filling.
There's a lot more - A LOT... after all, all those years of (essentially) experiments that hardly anyone ever performs. I've taken waaayyyy more chelators than even the doctors who think amalgam fillings cause poisoning and offer chelation treatments usually do, but since I have had success that could be clinically proven, and since I seem to be handling the whole thing very reasonably the doctor keeps filling my prescription. My conclusion, based on actual, sort of, "experiments" - on and off chelators, is that heavy metals have effects given FAR lower amounts than are clinically relevant today. I feel my conclusion is in line with science, given that we have reached the official conclusion for lead that the amount with zero effects is zero lead - and mercury is worse than lead (according to an NIH document I found). But you won't be able to detect those effects unless you try. The slow decline of health and mind is very subtle, I was "lucky" that I hit an extreme. I see soooo many people with issues I had, such as psoriasis, warts on the feet, colds that won't end, issues with eyes, etc. etc. - a looong list, that I have to wonder.... I DID take bio-chemistry, physiology, anatomy, etc etc. - at least a thousand ours of medical lectures and courses if not more over the last few years, so I am aware of the complexity. I just think that heavy metals contribute much more than is currently accepted. All you have to do to get (what I now think is) a significant amount of mercury is to eat lots of sea fish, especially the predators.
You're not alone there: my partner's tonsils "dissolved" when she was younger. I've never heard of this anywhere else until now.
