Thank you for your query on Healthcare Magic,
As your child is having constant nasal congestion
and requiring frequent nebulizations, it is better to rule out allergic rhinitis
and asthma with atopy by regular clinical follow up visits.
If child is having asthma treatment for short term and long term can be planned on depending on his symptoms profile.
So be in regular follow up with your Pediatrician
for proper evaluation and for appropriate medical management.
Hope i have answered your query.
