8 -10 white face bites put me in the emergency room a couple of summers ago. I hit a nest on mowing and it felt like burning embers shooting into my shins, at first I thought maybe the lawnmower was throwing sparks.
After about 30 minutes it was insane burning and itching in my lymphatic areas and my face started to swell up. Sitting in the emergency room it started to get worse and worse and the staff kept telling me they were still nine people ahead of me in line so finally I told my wife to just tell them I was having chest pain's. They wheeled me in immediately LOL
They jammed a harpoon of epinephrine into my thigh, I thought my heart was going to explode, Now I have an EpiPen prescription. The funny thing is I had had plenty of stings over the years something about the wfh really made me react poorly. Fortunately I have not seen wfh in a few years but I'm still pretty cautious around Yellowjackets.
