My 3 year-old daughter has had a fever for about 5 days (it comes and goes throughout the day, but has gotten up to as high as 103° and has been telling me that she hurts), she has a nasty cough.. I took her to the doctor and they tested her for RSV and influenza, and both came back negative. Idk what else it could be. It doesnt seem to be going away, and my poor baby is miserable (also off and on).
