Yep, I am allergic in that I react the most to yellow jacket stings and swell up to heck but location dependent I just deal with it... The first time in a LONG time (15 or so years I think) I was stung by a yellow jacket it was right above the left eye, I was leaf blowing and apparently got to above their nest, several of them dive bombed me and one got me... Anywho, a trip to the hospital and $550 later I was basically told to keep an eye on it and take benedryl, and given a prescription for steroids. My wife is around most of the time I'm doing goofy things so I use some Sting Kill and Benedryl and it works out...
On a positive note, I found the nest that the bastage was protecting, I was 10' from it when I got stung, it was 10" diameter and under a half wine barrel by the front porch... the nest is dead and received around 2 cans of spray...
