text: how do i prevent a burn from blistering? i spilt scalding hot soup down my arm as i took it out of the microwave; i've held it under cold running water for about 10 minutes, is there anything else i can do? if it blisters, it blisters. there is no way to stop it from blistering, but keeping it cool is a great idea. usually i get hot glue gun burns. get it under cold water asap and then check it for blistering. burns hurt so bad that i have to wrap them in a wet towel and getit wet every half hour or so. they seem to heal faster when you keep them cool.  sory, i hope you feel better soon!!!!!!!!!!
