hello Doctor! my son is 3.5 years old. he suffers from from cough and cold very frequently i.e once in 2 months. he is alsovery restless. pediatricians suggested that he has some allergic problem and suggested to protect him from dust. as he has started going to school now it seems to be quite imposible to avoid dust. recently we visited a homeopathy doctor who advised us for an x-ray of the nasopharyngeal area. the x-ray revealed that he is having adenoid which is suppresing the airway column obstructing the flow of oxygen to the brain which can be associated to his restlessness. my query is whether it is any inborn structural deformity, is it something really very serious..
