question: My daughter was at the doc today and suspected sinus infection.  102 fevers, vomiting, nausea when fever is up.  Feels well while fever is below 100.  I am having trouble keeping her fever below 101 even with Ibuprofen.  She also has had recent pyelonephritis in June.  neg. UA today but she acts just like when she had that in June.  She is 6 yrs old weighs about 45lbs.  They started her on Amox. today 800mg BID.  She took Omnicef for the pyelo in June.  She just presents so much like she did with the pyelo.  I can keep her drinking if her temp stays 100 or below but right now with Ibuprofen 2 hrs ago, it is still 101.  What else can I do?  Should she have vomiting when her temp rises with a sinus infection?
