And avoid this guy too. Yikes... And if stung, use Ammonia, and then shaving cream, and shave the unfired cycsts off (rinsing with every stroke), and then use warm sea water, warm salt water soak, or heat packs to help break down the toxins that are in the skin. So many people think urine is the 'fix'. Close... I've been stung once in the Caribbean, and it was the most bizarre experience. Like having electric wires dragged over my legs and abdomen repeatedly. I'm glad that was all it was too, no intense pain. I recovered in a few hours, and never actually saw anything, which added to the shock of the encounter. Oh, but I did have welts for nearly a week. They slowly disappeared, were itchy, and more annoying than anything. (DON'T PICK THEM!)
