Thanks for writing in.
It seems that your child's ear infection
has not been fully resolved and has probably recurred. It is very common for an infection in the ear to spread to the nose and the throat. The decision to take your child to the ER will depend on his age. If he is about 1-2 years old, it would be best to take him to the ER. Otherwise, you can schedule an appointment with his paediatrician in a few days. Also, give him steam inhalation and put saline nasal drops 1-2 drops in each nostril
For the fever
, continue with the Tylenol
and sponging with lukewarm water.
Hope this helps.
