Not about pregnancy but need info

Amanda • mommy of a 6 year old princess now expecting a prince💙👶🏽
My 5 year old has been getting random fevers for the passed month she looks ill a lot and complains of her stomach her doctor doesn't know what it is & when I took her to the emergency they couldn't tell me a lot of her blood work wasn't normal a lot of levels were high... I'm frustrated anyone know of a good website to ask a pediatrian a question ?
