After taking a bite of a cracker, Jacquie breaks out into hives and goes into anaphylactic shock. She is rushed to her Allergist where she soon discovers the truth about her violent episode. What is this mysterious condition?

Hi. My name is Jacquie. I'm from New Jersey and I suffer from a highly allergic reaction to flaxseed oil and sesame seeds. I was starving, and I took this multigrain cracker, and I ate it, and I immediately got sick. I called me allergist immediately, who was just right down the street, and he said, well, how far are you; I'm very close; he said come over right away. I got there and I went into anaphylactic shock is what happened. I got hives all over and my doctor took one of these, this is a called and Epinephrine pen, and he put it right in my leg. Immediately I started to feel better. I stopped sweating, stopped heaving, my hives went away. And he took a blood test, and it turned out I had a highly allergic reaction to flaxseed, sesame seeds. So I had to get these EpiPens that I need to have on my person all the time because you never know. I always ask at the restaurant, what's in stuff, make sure it's nothing funky, and so far so good. I have never had to use them yet.
