my 10 year old daughter has had nausea & has been really lethargic in the last 10 days. She started to get some red spots on her legs and upper thigh area 2 days ago. Yesterday they were better and she went back to school today. Tonight they have multiplied to her bottom, and arms. They don t itch, but a new symptom as of last night is sore elbows. Now tonight she s sore in her ankles & knees and both elbows. . . no fever either.
