HOT water, as hot as you can stand it. also, I know this sounds strange but, as a scuba diver I have also been told to put meat tenderizer on any stings. I actually carry it in my dive bag. Supposedly the combo of the two break down the venem in your system. you will probably swell up pretty good, but don't ice it, that will make it worse. If it gets really bad and you start to have respitory problems, go to the hospital, you may be having an allergic reaction. Good Luck!!
