My 15 year old has had a fever off and on since Wednesday, various other symptoms at different times: mild sore throat, headache, nausea, lack of appetite. No ear pain. Saw doctor Friday, he prescribed amoxicillin (did not test for strep). She does not seem to be improving, and her fever was up to 104.6 earlier. It always seems to respond to ibuprofen.  Any suggestions for what it could be and what else we can do? The high fever concerns me, am planning to call doctor in the morning.
Hello Your daughter is having high grade fever with sore throat, headache, nausea, loss of appetite, as all these symptoms are an indication of viral fever or flu. As amoxicillin is not providing relief. In such symptoms give her Tylenol (alternatively ibuprofen) whenever she develops fever, plenty of liquid, water, juice (without ice) and rest. Local antiseptic solution will provide relief in sore throat. Since after Wednesday only 4 days passed, so at least wait for next 4-5 days for complete relief. Still, if fever persist then consult another doctor and get his opinion. Hope this will be useful for you.
