I got stung last year.
Stepped out of the shower into a dark bedroom, grabbed a pair of shorts from the drawer, flipped them open, and pulled them on. I dimly registered something landing on the carpet near my feet during this process.
The moment I put my foot down I felt it -- ZZAP! Right on my big toe. Thought I had stepped on a needle!
The pain traveled all the way up to my ankle, but never past it. Foot was numb for several days after the insane pins'n'needles sensation went away. Coincidentally this was the same foot that I had broken the previous year--the later numbness was a welcome change from the usual soreness of the break.
Never did catch the li'l bastard. Sure am glad he fell out of my shorts before stinging me!!!
Found this in my search to check that I hadn't already regaled you all with my tale of woe...
I hate scorpions!
