Yes, most doctors are assholes. But it's better not to raise your voice or to use foul language during a "medical" appointment.
"text you write down" - you mean when you fill out forms before an appointment ?
We have extensive and comprehensive (and faulty) IT system that links up all doctors visits, most lab results (some are excluded) and prescriptions (deleted after 5 years for some reason ?!?).
if you say you used cannabis for medical purposes.. if you ever try to get benefits for long term disability .. people who sit on money can access these .. (and use in arbitrary way) .. if you get doctor to write down where your pains are and how they feel before and medication.. you have an official point of reference to compare/ refer to when talking if your pains are from what ever source or from addiction withdrawal.
In US I guess papers are clinic/ hospital specific so you would have to ask to get a paper copy with you.
While the idea of combined medical database sounds good.. it is more like 'anything you have ever said can and will be used against you if you ever have issues with child protection services or try to get disability benefits'
