Thank you for your query.
I can understand your concern. It is very difficult to tell the cause of the bumps described by you without seeing them. I would suggest you to wait and watch and see the effect of Benadryl
. Just ensure the face remains clean and dry. In case they persist then kindly show them to your doctor or a dermatologist
I hope I have answered your query to your satisfaction.
Wishing your daughter an early recovery.
