The last time I got a nasty burn from my oven I kept putting those frozen icy pole stick things on it - the ones that are in the plastic tubes. It was really nasty and I had a heap of pain from it so much so I had to have the tubes on it for many hours (one after another as each one stopped easing the pain - lucky we had lots in the freezer). My usual burn cream (Butesin Picrate) didn't help like it usually does. It looked like it would blister but it didn't & I think it was because of holding one tube after another for hours. It was the quickest I've ever seen a burn heal.
