<s>[INST] 13 month old with a temperature up to 38.8 goes down with tylonol now back down to normal today then woke up screaming uncontrollably (never cries) what could this be? she has alot of teeth esp the side big ones all came in at once a bit ago. could it be possible that its a sign of two year molers? [/INST] Hi... Thank you for consulting in Chat Doctor. 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. I DO NOT THINK THIS IS RELATED TO MOLARS. Regards -  </s>
