Thank you for your query.
I should commend you for taking the appropriate steps in your son's case. You can wait and watch. In case his respiratory rate
increases or he develops a cough
or he becomes febrile then you should consult your doctor and get a x-ray chest done to rule out pulmonary complications
. However by the description provided by you it appears that your son is well settled and would not be requiring any further medical attention.
I hope I have answered your query to your satisfaction.
Wishing your son an early recovery.
Rajiv K Khandelwal
