I took my 21 month old to the doctor today and they said it wasn’t hand foot and mouth. Since the doctors appointment i’ve noticed her rash has gotten significantly worse. She hasn’t ate much in the past few days and she has gotten very little sleep. she’s constantly playing with her feet and refuses to wear any sort of clothes including a diaper. the rash is literally all over her and the doctor only looked at her hands and feet. she wasn’t prescribed anything either. what could this be?
