Hi, I am Dr Sonia S V. I am an ENT Surgeon & Head & Neck Specialist.In this age group the problem of a post nasal drip
may be due to adenoids.Adenoids are tissues like tonsils situated right at th eback of the nose and blocking th enormal breathng through the nose.Many children grow out of it but some require specific treatment for the adenoids as adenoids can cause nose block,cough
,ear indfections, hering loss,repeated colds etc.Do meet a good ENT Surgeon in your locality who can diagnose if your child is having adenoids.
All the best
Dr Sonia Suprabha Venugopal
