[|Human|] 9 year old boy, healthy, no allergies, NKDA. In the last two months, has become sick, very suddenly at night. No fever, no vomiting (though he thinks he might). Severe headache, hot/cold, general malaise. attributed it to dehydration first few times but I have been strict about water intake as of late. worse night was tonight, he seemed to not be able to get comfortable at all (body aches?) Cool compresses helped, finally asleep. Seems like the flu but no fever and usually wakes up feeling 100%. Any ideas?
[|AI|]  Hi.... Fever of few days without any localizing signs could as well a viral illness. Usually rather than fever, what is more important is the activity of the child, in between 2 fever episodes on the same day. If the kid is active and playing around when there is no fever, it is probably viral illness and it doesn't require antibiotics at all. Once viral fever comes it will there for 4-7 days. So do not worry about duration if the kid is active. Hope my answer was helpful for you and if so rate it if you are happy.  I wish your son a speedy recovery. Regards -
