This is probably a long shot to settle definitively, but I’d like some opinions.
Two days ago, I felt a sharp sting on my right inner upper arm. It wasn’t terribly painful, but enough to make me jump up and do that little dance you do when you think you’ve got something in your clothes, but you’re out in public and thus can’t just throw them off. There was some buzzing in my shirt, but the perpetrator itself never emerged.
After I got home, I inspected the site, and found four or five small-ish welts (1cm diameter, I would say) with a red dot, like a puncture wound, in the center, which was about 1mm across (which both me and my wife thought rather large, with her joking that if that was made by the snout of something, it probably was an elephant—this works better in German).
I applied some Fenistil Gel to the area, and otherwise went on with business—there was no itching, and the pain was comparable to a sore muscle.
The next morning, I looked at the area again, to find that some of the bites had formed small blisters, and an area about 5x15 cm was red and somewhat swollen. The pain was still mostly comparable to a sore muscle. Today, there’s just a little bit of redness left, and it’s a bit tender to the touch.
I live in Germany, in Cologne, to be exact, and pretty much the only insects I know that have a defensive sting around here are bees and wasps. A bee, however, wouldn’t have stung more than once, and the reaction seems to mild for a wasp sting—last time I got stung by a wasp, my entire thigh got red and swelled up. Maybe I just didn’t experience as severe a reaction this time? Any other ideas?
