"Basically, you have to double-check everything they do, and endure their cynical rebuttal when you make suggestions, ask questions or try things they didn't request."I had frequent headaches and the student health service referred me to a well-known and very respected hospital for tests as an outpatient. The doctor to whom I was referred was a well-known neurologist with papers to his name—probably the most eminent neurologist in the country at the time (even now, some decades after his death, his name appears on Wiki as someone of eminence).
He then sent me for a series of tests at the hospital and they extended over a number of days although not consecutive (which was inconvenient). Those tests were rather exhaustive and included amongst others neurological tests, brain x-rays, electroencephalographs and testing my eyes including injecting fluorescein into my veins to improve the contrast of the photos they took of my eyes/retina—afterwards I was pissing out that brilliant florescent yellow dye for the better part of a day.
Keep in mind that those tests involved other doctors and clinicians who would have examined the neurologists report, so decisions weren't taken in isolation.
After all that and multiple visits to the hospital he said that they could find nothing wrong with me and suggested that I be admitted for at least three days for further tests! I declined as I was about to have uni exams and never did return to be admitted.
Several months later I visited a local GP practitioner because I'd had a bad dose of the flu and after he'd dealt with that I mentioned my ordeal at the hospital.
He was palpably furious and mumbled quietly under his breath which was just audible enough for me to hear "fucking idiots". Within a split second he went on to say "presumably during all this testing no one actually suggested that you might have migraine?" to which I replied "no". That made him even more annoyed.
He then prescribed a common Parke Davis formulation called Ergodryl, which, back then, was a common go-to drug for migraine, it's a formulation of egotamine tartrate, caffeine and diphenhydramine (a well-known antihistamine).
Problem solved, that drug completely killed my headaches. I've never forgotten that incident and although I've experienced similar inept performances I've never experienced one on that scale again. Ever since I've never fully trusted a medical diagnosis unless confirmed by second options and backed up with tests. It pays to be not only cautions but also to do one's own independent investigations.
From my experience, not all doctors are mediocre to the extent that I'd wished I'd seen another, some I've visited are quite exceptional and have an innate ability to cut to the core of a problem immediately, or at least start investigations on the right footing. Unfortunately, from my experience, they seem few and far between in numbers.
I was once introduced to a state director of health (the State's top medical officer) through a common interest outside of medicine and I got to know him relatively well. Some time later I mentioned that incident and he said to me without hesitation that he would not trust 90% of his profession to make a competent diagnosis, and he went on to say that if I were ever to be stricken by some dangerous life-threatening disease that I was to give him a call and he'd provide me with a short list of the competent ones who he'd trust—one's that he would go to if he became sick. Fortunately, to date I've never had need to take up his offer.
Frankly, for the lay person this has to be a significant worry. How on earth does one know who is competent and who is not, especially if it's at short notice?
