First of all yes I have had a steam burn the last one was on Thanksgiving, can I say ouch. Second I am sorry to hear that you burned yourself. Third of all for future referrence don't put butter, or vaseline on a burn it can make the burn worse. Instead run lots of cool water on it or a cool compress that you are constantly rewetting with cold water, you might be doing this for a long time, you really shouldn't put ice on it either as it can damage the already tender skin with frostbite. Then you can put aloe vera, solarcain, or another otc burn cream if you want to put something on it, but it isn't necessary and cover it with a band aid or gauze. Sending

that the burn heals quickly.
ETA: I see Elizabeth already gave directions.
