My 10 year old daughter had a fever of 103.2 on Monday. She complained of a sore throat and upset stomach. I took her to a doctor who said she had all the symptoms of Strep, even though the quick test was negative(could be false negative). He put her on antibiotics. I continued to treat her with ibuprofen to keep the fever down, which began to rise to 104.2. No change occured since, except no sore throat and stomach ache, so I took her to her pediatrician today. He said it s not bacterial, but may be mono. He confirmed that she has an ear infection and took a blood workup. He advised me to continue the antibiotics, because she must complete it since starting it. She seems fine one minute and then sleep for a few hours the next. I m checking her temp every 3-4 hours and it s always up. I give her ibuprofen at 4 hours. I just took her temp and it s 104.4. I m concerned and wondering if I should take her to the ER. Please advise.
