Hi.
Thank you foe your question.
From the symptoms of your son,it seems to
Bacterial gastroenteritis.
However to confirm it I need to know certain answers.
What is the age of your child?
Had such illness present in past?
What antibiotic you gave?
Did the child had worm infestation?
Is it associated with
vomiting,
abdominal pain,passage of
blood in stool,body ache?
Is the child weak and dehydrated?
I will advice you to have some investigations done:
Complete Blood Count
Stool culture and sensitivity.
Child must be well hydrated.So give oral
Dehydration Solution.
Ensure that the child is on proper diet.
Start antibiotics only after the stool culture report comes.
Wish you and your son healthy life.
Best wishes.
