My ds14 started getting a fever yesterday. It started out at about 102.5. Then today it has averaged 101. He has only taken a few doses of Dayquil and then Nyquil last night and tonight. Before I gave him this dose tonight, he vomited once and his fever was at 103.7. Other symptoms are mild cough, aches, head/eye ache. He has continued to eat a bit and is staying well hydrated. We don't treat fevers unless there are other pains going on or other symptoms in general where the benefit of medication outweighs the benefit of the fever itself. How high is too high before I take him to the doctor? I've read conflicting ideas from medical websites.
