my daughter got burned on her belly on sunday night (1st & 2nd degree burns), I took her to the dr on Monday. the dr gave an rx for silver sulfadiazine cream . I have been putting the cream on 1-2 times a day, thick like icing , just like they told me to. the first couple of days it seemed help, the burns seemed to be shrinking, however now one of the original blisters has popped and a new blister has formed farther down. should I just keep using the cream thickly as directed or should I lay off for a day and let it air out?
