pee!!! yea OK when I was a kid in Greece I got stung on my shoulder by a jellyfish and grandma said you gotta pee on it thank got I had pretty good aim . It didnt help.
im an avid diver and fire coral really likes me. pee actually does work, its the uric acid in it that doea th ejob. but vinegar is an easier way to go. all that does is basically neutralizes the stinging cells. my hammer stings me all the time just feels like a pinch and nothing ever happens. i would imagine most people r that way unless u have some kind of crazy allergy which u probably dont bc u would have seen the reaction by now. anyway learn to love the pain...reminds u ur ALIVE!!
