I had a bee or wasp (I didn't ask it which) fly into my ear as I was cycling in the Pyrenees. It wouldn't come out, so I used the flappy bit of my ear to squash it and then hoiked it out in small bits at a time with my little finger.
had a very swollen and painful lughole for a day or so.
Another time, I had one fly straight down my throat and sting. Had no option but to swallow, take another hayfever pill and eat lots of ice cream... to control the swelling and to console myself!
