You are lucky, the thing that is scary with my wife is how quickly she can go from irritating symptoms to something much more serious. There are no food allergies in my blood relatives either, but several relatives are allergic to bees including both my father and uncle. Both of them and my grandmother had breathing difficulties related to bee stings.
I have a severe reaction to pseudoephedrine... it makes all my skin peal off and causes other issues as well. I also had a severe reaction to poison oak, but I am not sure if I am more allergic to it than others or if I just had a worse exposure. While fighting a brush fire, I got poison oak in my clothing next to my skin and it remained there for hours not really bothering me since we were so busy, but that evening I had a systemic meaning that I had problems even in places that had not been exposed. The allergen travelled through my blood stream. Neither of those reactions caused breathing difficulties however so they were not life threatening.
Yeah, I know what you mean. My baby daughter got poison Ivy. So I went out to rip out all the plants without being careful.
Well Mr. Nature boy, yours truly, got poison Ivy all over his arms. Lesson learned.
BTW, thank you for saving lives. There ARE those out there that really appreciate this kind of thing.
