Apologies - I wasn't intending to be "dismissive", and no "personal attack" was intended. I'm simply reflecting on the tone of the several comments you've written, which seem angry, IME beyond the norm for someone simply discussing on a story on the internet.
> "This is so typical of Swedish doctors. If something doesn't work, it's ALWAYS the patient's fault. If they don't know what a problem, it's ALWAYS psychosomatic."
Re-reading this, I think I can be forgiven for the suspicion you've some history with the Swedish medical establishment? :) But of course, apologies if this is not the case.
> It is never acceptable for experts to lie.
You're wrong to call the doctor's note about an assumption they were making "a lie". A "lie" is a deliberate untruth in order to deceive, and that doesn't appear to be the case. Of course, hindsight proved them wrong, but at the time they were merely making an assumption as to the possible cause, presumably based on education, experience, and probability.
Medication errors are common, communication issues between patients and doctors are common, a patient lying to their doctor is quite common, Munchausen syndrome and poisoning are very uncommon.
They could have written "Of course there other unlikely explanations, but my current prevailing hypothesis based on the balance of probabilities is...", but... no-one's perfect.
> ‘I don’t know’ is rarely an acceptable position for an expert, especially a doctor.
I don't know what would make you believe that. It is never acceptable for experts to lie.
