Thank you for your query.
I can understand your concern regarding your son's illness. Though you have mentioned about a shadow on the X-ray you have not shared any other investigation findings. Were blood, stool and urine examined?
If your child is constantly throwing up and running fever
then he needs to be re-examined and, if required, admitted for rehydration. I would refrain from using Augmentin
in diarhhoea as it is known to increase the frequency of motion in a number of cases.
I hope I have answered your query to your satisfaction.
Wishing your son a speedy recovery.
