my daughter is very sore in her nostrils, i can see tiny bumps, it is crusting over and causing her alot of pain, it is very red. She also has a few spots around her mouth, one of which looks like a blister. She also is very sore in the top of her ear where it folds over, it is oozy and red. Any idea what is wrong? She is sneezing alot and seems congested but says she is well apart from that. she is 5.
