Hi my 18 month old son went to the doctor a week ago very sick high fever 103/104 they sent him for blood work and it came back that his neutrophils and white blood cells were very low they called it neutropinic they said he either had a bacterial or viral infection wernt sure which he had a broad spectrum antibiotic shot given to him as well as a strong prescribed antibiotic and had his blood tested for 4 days until they said he was back to normal levels now this week today I took him back in with 101 temp and he was diagnosed with severe ear infection in one ear sent us home with antibiotics just a hour ago his temp spiked to 102/103 and he is vomiting also has only had one wet diaper since 1pm today I feel like maybe I should take him back in ? Is there any other things I should be worried about or is this normal ? Thank you for your time..
