About two years ago, I was mowing the lawn up at my camp when I drove over a nest of white headed wasps (ground bees). They were all over me before I knew what was going on. In a panic, I ran inside to get away from them, trying to brush them off me. They followed me in. In the process, I was stung...alot. My guess, about 75 times, mostly along my R hand, ankles, lower legs and feet. I pulled off my socks, to find them down inside them, and in my pants leg. I was in a bit of a panic ,and knew this could be serious. I grabbed our allergy relief benadryl and took four, then went to my neighbors explaining what happened, asking to stay there for an hour or so to be sure I didnt have a severe reaction. Luckily, I didnt...but an hour later, I was still picking them off.
I called the wife to tell her what was happeining, and headed home....it was a long drive, and the next few days were the most miserable I ever had. I had to call in sick a few days, and two months later, my R hand was still swollen twice the size.
It took a couple weeks, but we returned to the camp with a vengeance.....fire bombed and dug up the nest, and several others we found. Everything has its place...but not those little bastards.
My recommendations...dont do what I did....IF you get attacked with multple bites...get around someone to watch you, and dont be shy about going to urgent care/ED.
