Good day, the child had a temperature three days ago of 38.5. We called a doctor, who said it was tonsillitis with white coating, and prescribed Augmentin. He has been feverish all these days, reaching up to 39.6, he cries at night, his legs are cold during fever, he doesn't eat anything but drinks, today we were called back for a check-up (everything is clean), they looked in his throat, also saw the coating, and prescribed a referral to an infectious disease clinic, they said to go for injections, but today he plays normally, only eats little, I am thinking whether to send him or should consult another doctor? It's not really good
