If you mean, like, an insect sting or something along those lines, I don’t remember exactly. It’s probably been a few months since my last ant sting. Never been stung by a bee. A few years since the last wasp sting. Don’t recall ever being stung by a scorpion or centipede, though I’ve inadvertently stepped barefoot on the former once or twice. (They’ve been more perplexed than angry.)
