I don’t know about the science here, but I believe it to be true. I haven’t been stung in at least five years, except for last weekend when a hornet got me on the bottom of my foot. My foot was swollen for practically 36 hours and sore for three days (when the normal reaction is a few hours). But as soon as I took Benadryl, things looked better. Plus, my mom told me I probably became allergic because she’s heard the same thing. Any reaction to a bee sting is an allergic reaction, doesn’t necessarily include anaphylactic shock.
