Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: Pediatrics, please!Hello! Worried Mom here.Patient is 5 years old (almost 6). He weighs 35ish pounds and is in the 90th percentile for height. He is a picky eater, but there has been no loss of appetite.His symptoms are diarrhea. I believe this is from lactose intolerance (his dad has the same issue) because the worst episodes are after he consumes anything that could contain lactose.What I am concerned about are the dark circles beneath his eyes that have developed lately. These two symptoms (diarrhea and the dark circles) pull up neuroblastoma when I Google (I know, no Googling). I had a friend whose child had this so it hits a little closer to home, but I know its rare.He has an appointment Monday. Should I push for tests? Or is it probably just lactose intolerance and allergies/lack of sleep and I am just freaking out as a Mom?I do have health anxiety that is being dealt with by a professional- counselor and medication - but every time my children are sick I always jump to cancer.Thanks for any advice!. ### Response: More concerning that he's not hydrated well, or very tired. Neuroblastoma, just...no. Not up high on the differential at all..
