Hello, we've been experiencing symptoms for two months now. Last week, we had a fever for three days at 38.8 degrees Celsius. We had a sore throat, some cough and a stuffy nose. Our pediatrician prescribed Augmentin and Efferalgan, and today, the temperature went down and there were some rashes. I read online that it might be roseola, but I'm not sure if anyone has experienced this before. Could you please tell me what it could be?
