I have hypercortisolemia since 25 years at least. I have been to various endocrinologists to investigate this.
It has caused numerous serious problems including blinding me in my left eye (from a cortisol related condition), osteoporosis, weakened immune system and other problems.
Every time they test me for a tumour, find no tumour and in every case I was told, "there is no problem".
Even though the high cortisol is screwing up my health. They do not know the cause so there is no problem.
Once the recipe book is exhausted they are just totally lost.
My brother had a problem that was eventually found to be due to salycilate intolerance. But in the meantime, until this was found, he was told he was neurotic, imagining it etc etc.
My mother was prescribed anti-anxiety medications when she actually had hypothyroidism due to a tumour, with classic symptoms.
Just about everyone you speak to has a story of delayed or misdiagnosis, problems being dismissed or denied because they didn't fit someone's cookbook.
The sooner we have AIs doing diagnosis the better as far as I am concerned.
Overworked humans suck at being humane.
No they don't. They try to give you the best advice that they can at that point in time. But I've never met a medical professional who thought they knew everything and anything.
What are you saying is really quite rude and dismissive.
