Thank you for your query.
With all the complaints mentioned by you I believe that your son needs to be examined by a doctor so that he can be treated for the problems that he is having. I fail to understand why he is receiving Augmentin
without being examined and investigated for the problems. You can continue with paracetamol/acetamenophen and bath to reduce his temperature till you see the doctor.
I hope I have answered your query to your satisfaction.
Wishing an early recovery to your son.
