If this heat rash? We’ve been having problems with my daughter skin for over a month now with regards to blister type spots popping up on her currently waiting for urgent dermatology appointment because doctors don’t know what it is… anyways this has nothing to do with them (I hope) she’s got this rash she’s had it since Wednesday it is now Monday it’s gradually got bigger covering the whole of her back and bum and going down her arms. She’s on an antihistamine anyways to help her stop itching the spots she’s got but this rash is really bothering her as you can see on the pictures. Does it look like a heat rash? Is there anything I can do to help her 😔
