Sheesh! At my age I had a 'first experience' with nettles yesterday - NOT to be recommended! I was clearing out some weeds on the backside of my woodstacks with a weedwacker wearing (of all things) shorts. The dang nettles were about 3' tall and they fell against my bare leg when I cut them. Wow-zers! Like a razor blade - actually two razor blades because it happened twice. To make a long, painful story short I checked out the internet and did a two step treatment: 1. Used duct tape over the affected area, smoothed it down and tried to pull out as many of those hairy nettles as possible. 2. Made a water based paste of baking soda and smothered the area - cooling relief but it didn't last too long and I simply hose rinsed it off my leg and reapplied about every two hours and tried to keep my leg elevated for at least 1/2 hour each time. For bedtime I did a fresh paste, let it dry and then covered it with a piece of large gauze & tape and then drizzled a very small amount of water over the gauze following up with 2 Advil. Lesson learned -don't cut weeds in shorts.
