Thank you for your query.
I can understand your situation.
The child is suffering from post viral allergic cough
Your child needs a chest x ray
and a cough suppressant along with the prescribed antibiotics.Consult your physician if the cough turns worse.
I would advise you to keep the child at home and give him rest and plenty of fluids.
Hope this answers your query.
If you have any other queries kindly direct them to me.Wishing your child a speedy recovery.Have a nice day.
