Hi,
Thank you for your query.
With 2-3 pus cells per high power field, I would personally wait for a day or two as the stools will settle down. You can add some
probiotic syrup (containing
lactobacillus) to recondition the intestinal milleau and ensure that that he does not get dehydrated.
I will consider lactose free milk only if there is no improvement and stool shows presence of reducing substances.
I hope I have answered your query to your satisfaction.
Wishing your son a speedy recovery.
Regards,
RKK
