Well all the best to him and I hope he recovers very soon.
I know at home this year, we are inundated with wasps, you cant sit outside for more than 5 minutes and you are swatting them away. I got stung in
Greece about 7 years ago, once on the stomach, which was fine as Phill sucked the sting out, and then I got stung on my left hand. I had to go to the Pharmacy and get creams and sprays, but by the time I came home, my left arm was swollen to my elbow, I had to go to A+E the same day and they had to cut my rings off.
