Hello sir/mdm, My son is three and half months old. He has fever from last 2days. Sometimes fever increase upto 103 and sometimes it is 99. We went to the hospital, he is in under treatment. We did blood test but reports are normal, but still he has fever and crying most of the time. But we are not clear why this happens, what are the reasons, where we made mistake. Please suggest/consult we worring about him. :(
