Girls, hello everyone. Very urgent question, who had children with pneumonia? We spent a week in the hospital, received antibiotics course, and now we were discharged, day was at home, everything was great, and today from morning started shortness of breath, and temperature 37 was. And in the evening 38.3 already. In addition, they prescribed home treatment, inhalations and antibiotics tablets. Can there be fever on antibiotics? Already no strength, hard ? little one feels good, cheerful. I want to observe for now, if something immediately ambulance. Maybe someone had it like that?
