To some/many it would seem reasonable to expect an apology for a mistake but on the other hand it is distinctly unrealistic to expect one from a member of the medical profession, individually or collectively. Sadly, it is only too easy to come across incompetence there and all too often leading to an early death. Society puts these people on a pedestal of sorts and is in awe, and this in turn has encouraged arrogance and carelessness among far too many medics. If the system by which medical services effectively leave you little choice as whom you get to listen to your request for assistance with some ailment then you end up stuck with a reaction, wrong or right that becomes the diagnosis - including that there is nothing wrong with you except your mind. It is true that doctors bury their mistakes and in all likelihood it will continue without lessening at all.
