There are a lot of negative comments and criticisms here. It is very easy to make these negative comments, but I have not seen any constructive criticisms, nor any intelligent suggestion on how to make a better medical symptom. I see nothing mentioned in this thread that can be used to improve the medical system. Moaning is of no help. If you look at this article on How Common is Misdiagnosis, you see that misdiagnosis is massively commonplace in medicine. What are the reasons for this? How can the situation be improved? How is it that this same situation is present all over the world? These are questions you should be contemplating. I'd like to hear your intelligent and insightful reflections on these questions. If you just want to moan without offering any suggestions, well, you are not making much effort. No, I am not defending the medical system; everyone wants a better system; I am just pointing out the inherent difficulties of making improvements. It is a very complex issue, and you cannot just shirk these complexities. You saying this is exactly what I mean about shirking the complexities of this issue. You missed the point I was making about allocation of funding in order to maximize the effectiveness of the health service.
