my child has cough... i went pediatrics, he suggested to take neplization.. after 5days it cured.. but now cough will come again what is the reason?? what I can do

A. Maybe cough didn’t subside completely because nebulisation actually helps a lot in reducing down and clearing the cough from the chest and throat of your child so it’s a very good thing to be done if the child again facing the problems and you have to consult your doctor again
