#asktheexpert Hello doctor, My son has had recurrent fevers for the last 2 and a half months. The first time, it was diagnosed as viral fever. It subsided after 10 days. But after that, it has been due to a urine infection. He is getting a fever every three days if he is not using antibiotics. Got an MCUG test and no reflux was found. Please suggest what tests to be conducted. His CRP is constantly high during fever reaching 56.
