question: My daughter was brought into the emergency room last night because she was running  a fever of 103. After the doctor looked over her, he found a slight ear infection, so he prescribed antibiotics, and said to give her tylenol every 4 hours which we are doing, but as soon as the tylenol wears off, especially in the evening her temperature goes back up, i'm not sure whether we should be worried or if her body just needs another 24 hours to let the antibiotics work, and that's why she's still running a fever.
