i think your missing the point people that are allergic from this are alergic with stuff there whole lives like peanuts for example. you dont just wake up one day and go oh im allergic to peanuts or sea food. so what you have to try and figure out is when you got ec what were you doing different to the rest of your life for me it was putting lip balms on when i went through high school i never once put lip balms on. 6 months prior to me getting ec i was putting lip balms on like 3 times a day. the question is was it the lip balms that caused ec or was the lips reacting to something which was making me put lip balm on becasue they were uncomfortable well i guess thats the whole big question about ec. and allegries dont continue for years! if your allergic to seafood and eat sea food your body has a reaction and then it gets over it after a few days!
