Allergies are quite common among people, do you have any allergies? My spouse is allergic to ginger, bananas, and all types of fish. I'm not sure what I'm allergic to, I had a weird reaction to something a few years back. At the time, I worked on the opposite side of my building and in sheet metal where I handled hinges with my bare hands. I got this terrible rash on both of my arms, they were super itchy and swollen. I went to the allergist, but they just labeled it as "contact dermatitis" and never figured out what caused it. I had to use steroid cream to cure it.
