Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
He has loose motions, abdominal pain
, and fever
. You gave tablets for symptom relief, but not for cure.
For complete relief he should use medicines to cure the infection.
I advise you to consult a physician for diagnosis and treatment. He may need to be infused with fluids, if dehydration
Wishing for a quick and complete recovery.
