Because I have, and he died. Went from ok to dead in 3 days. Violently. In hospital. The details are so simple, and so distinctive, that I can't out them on yer interweb. But at the inquest the doctors lied. Then lied again in court, as it happens, so no one can talk about it even 5 yrs on as it's still doing the court rounds.
So what has happened to you and the people you know? I'm posting because the expression 'everyone makes mistakes, even dedicated NHS staff' on a current thread has made my teeth itch.
