Hi, Welcome to Hcm, I m glad to hear that your child s tonsils have become better following antibiotic therapy. Now the symptoms you mentioned seems to me due to viral infection which can be just upper respiratory infection or if you live in a dengue epidemic area,possibility of dengue needs to be considered. As a remedy at home, child has to take plenty of liquids, paracetamol in case of fever and ssevere pain and rest. Hope this helped. Happy to clear any further queries. Take care.
