I used to think the sting was okay and then cleared a largeish patch wearing a T-shirt, shorts and no gloves. (Me, not the patch.) I couldn't sleep for the tingly legs, all the next day they tingled to a very distracting extent, and I was then hyper-allergic to nettles for years and years.
I'm back to normal with them now, but you can be sure I wear protective clothing to do more than pull up a few bits that are between me and a tap.
