Where to report an adverse event officially, by region Writing it up because I had to work it out twice and would rather nobody else did.
Reporting an event with the dates and the sequence, because attribution is impossible without them.
What happened, when, relative to the dose, and everything else that was in play at the time. I am not claiming causation and I would like to know what would establish it.
Nothing here is medical advice and I am describing my own case rather than asking anybody to diagnose it.
