Hi
Thanks for posting on HCM
Strep throat will give your son all the symptoms you describe.Amoxillin is a good antibiotic for strep throat.With inflammed tonsils, swallowing may be very difficult.I will suggest :
-Continue with amoxicillin
-Add a pain/anti-pyretic/antiinflammatory medication like ibumol
-Give the child warm liquids like lemon water and tea
-Give
cold liquids occasionally to help numb the throat
-An air humidifier will be good in the room
-Sucking of throat lozenges
-Try gargling with look-warm salt water if the child can
If the symptoms persist, you will need to see your Doctor for reevaluation and to judge the need for an amoxicillin-
clavulanic acid combination since its not the first time the child is having this infection.
Hope my answer will help you
Best regards
