5 year old with a fever for 4 days now, have been doing the motrin/tylenol thing and it does bring fever down to 101...also have done baths. Fever has been at highest 105.4 today. Doctor doesnt know what is wrong and actually told us to lay off the meds because she has already had too much, so without tylenol her fever climed to 105.5 and I decided to give her meds. Not sure what to do. Ears, nose, mouth stomach etc all fine...white blood cell count fine, chest xray fine, no flu or strep!
