I am worried about the blood test report of my son. Please guide us.

Hi doctor,

This is regarding the treatment given to my son for viral fever. He is 8 years 3 months old. When we observed my son's fever, I gave him one teaspoon of P250 for three days. On the fourth day, I visited hospital due to continuous fever. As the blood report confirmed it as viral fever, he was prescribed with P 250 and antibiotic pills 100 mg (four tablets). Also, he was given Piperacillin and Tazobactam injection (half morning and half evening) for the next three days. My son has become weak, did not eat food and had vomited. After three days of injection, he was little better and had some food. We had another blood test after three days of injection and I have attached the report. Again, the doctor advised us to continue the same injection and he had the same for the next two days. Now, my son feels better and eating all kinds of food. Now, we are yet to meet the doctor for follow up and blood test. I am so worried about his blood test reports. Please guide us doctor.
