I got into a patch of stinging nettles a few years ago when weeding my garden. The description above of feeling like I had walked into a hornets nest is right on. Luckily I also grow Jewelweed (Impatiens capensis). I broke a piece off one of my plants and rubs the sap all over the abrasion. I stopped the stingging right away but I was left with the numbing sensation in my hand for 2 or 3 days.
