This is the first time I've ever been stung. I was rehousing my adult pair of Hadogenes paucidens, and my male was relaxed enough to let me tail him without problem. My female decided to be a bit more feisty and somehow managed to flip her tail around and tag the side of my index finger.
The initial pain was just a "prick" sensation, and me wondering if I'd actually gotten tagged. It later rose to a dull, slightly throbbing, but almost non-existant pain. A few minutes later and it was slightly numb-feeling.
It's been about ten minutes and my finger feels a little irritated, like I poked it on a blackberry bush several hours ago.
I'd post a picture, except the sting was so minor I can't even see the sting site.
Update: It's been around an hour, and I can't really feel any more effects of the sting.
If your emperor scorpion stops eating, don't panic.
Be nice -- you were a noob once, too
