question: My son has had high fever for about 10 days. He is 4 years old and weighs 20kg. He had a running nose a week before he got fever. In the initial few days fever was around 102-103 in the armpit. After about 3 days of fever we gave him an anitbiotic (azithral). The fever didn't get better. It would get better when we gave crocin or meftal. Now we are using another anitbiotic calle Keflor. In the last two days, when we give crocin or meftal, the fever stays down for about 9hrs and starts to come back. We are on day 3 of a 5-day keflor course. We are wondering if we should get a blood test done. He is not eating much.
