Detailed Answer:
Hello

Thanks for the query

I have few queries like
1) For how many days ache is there?
2) How severe the ache is?Is the pain severe enough to disturb sleep or daily activities?
3)Where exactly the pain is i.e. upper abdomen,lower abdomen,around umbilicus?
4) Is there any other associated symptoms like vomiting,urinary problem or abdominal distension?

Bifilac contains probiotic (normal healthy gut bacteria) and can be used in any condition except few like necrotising enterocolitis. So there is no harm in giving Bifilac but I can not justify it's use in pain abdomen.
If pain is not severe, not associated with vomiting or urinary problem then mild antispasmodic agent like dicyclomine (colicaid/coaid) will help as most of the time the exact cause of pain abdomen is not known in such cases and it get relieved with this treatment.

But as causes of pain abdomen can vary from mild to life threatening condition the exact management will depend on the proper history and clinical examination.
I request you to give me the answers of the queries so that I would be better able to help you out.
Regards

According to the details provided, it appears to be due to gastroenteritis.Most of the time it is due to viral infection and symptomatic management is needed.
As there is disturbances in normal gut flora in gastroenteritis, giving Bifilac will help.
If pain is severe enough to disturb sleep an antispasmodic agent like dicyclomine may be needed. If vomiting recurs antiemeric like ondensetron may also be needed.Both of these are prescription medicines, please get it prescribed by your physician.
