Five Symptoms to Watch For: Watch out for these symptoms in addition to fevers as they may be signs of a serious – and possibly dangerous – illness. Keep an eye out for the following five symptoms, which could indicate a problem when coupled with a fever.
Your child has lost his appetite, has little energy, or is noticeably pale of flushed, or you notice other changes in his behavior and appearance.
Your child has small, purple-red spots on his skin that don't turn white when you press on them, or large purple blotches.
Your child is unable to swallow and is drooling excessively.
Your child has difficulty breathing even after you clear his nose with a bulb syringe.
Your child seems delirious, glassy–eyed, or extremely cranky or irritable.
If you notice any of these symptoms with a fever, call your pediatrician right away.
In general, it's a good idea to check with your pediatrician if you feel uncomfortable about your child's appearance or behavior, no matter what his temperature is. Trust your gut.
Remember, too, that fever is only one sign of illness. Be sure to mention symptoms such as a cough and ear pain (if you suspect it) or vomiting and diarrhea – these can help your pediatrician make a more accurate diagnosis.
