My 9 year old daughter has a rash (bright red, very even all over with some hive looking spots- but mostly all over prickly and red like sunburn) on both of her feet that cover the tops and up the ankle. It is very itchy and uncomfortable. Her hands are bothering her too and are puffy. Her cheeks looked flushed as well. She felt sick on SUnday and threw up. Was totally fine MTW, and then today didn t feel well- headache, no appetite, chills, prickly skin. Then we noticed the rash at dinner time. She is asleep now after a dose of benedryl. Would this likely just be a viral rash?
