a severe reaction to shell fish
I should imagine that this would be the eyebrow raising statement to the medical authorities who are paid to look after the health of your passengers, and those who live beneath your flight plan. The mention of an
epi-pen may wake the AME's from their Winter hibernation.
The more you involve medical experts, the more questions you will face.
If you threw up after a dodgy prawn, then I'd leave it at that. If you collapsed after emptying an ash tray that contained an empty packet of
skips then it may be best to seek further advice.
