I see what you mean. Nevertheless, even though allergies run in my family, I can eat shrimp, shellfish all day long with nary a problem.
However, I DID develop an allergy to yellow jacket bee stings, after being stung about 19 times when fighting a hive about 10 years ago.
My face swelled up and I decided to stick it out and not call 911. (I was without my family at the time)
I’m lucky to be alive after doing so many dangerous things in my life. The Lord must like me, then. Doesn’t make any other sense.
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.
