... If someone is allergic to eggs? There is this part in a short story that I am planning to resume for a collection where a character becomes possessed, and I got the idea in my head that he was about to be forced to consume an egg, something that he was allergic to. Personally, I'd feel lame if it turns out that no one had ever died from consuming an egg if they suffered from egg allergies, and I had tried on my own in the past to research that, but PEANUT allergies kept coming up instead. So could it be potentially fatal? Or should I just switch his allergies to peanut? I really don't want someone to find this particular part funny if it turns out that I was all wrong about how severe allergies work. I would personally be terrified if someone tried to do themselves in that way, if I didn't know that they were possessed. Any response would be welcome.
