Hello. My seven year old daughter threw up last night one time and then seemed better today. She didn t have much of an appetite today but held food down and seemed almost back to normal. Late this afternoon a rash showed up on her left arm and seems to be spreading to her other arm (lightly) one on her shoulder and one on her face as well. Not much on the torso. They are not very itchy and she is not feverish, but she is back to feeling like she will throw up. Should I be concerned and what do I look out for?Thank you, Shaye
