Hi,I had gone through your query and understand your concern.
Asthma is chronic inflammatory disorder of the airway.There is no permanent cure of it.But the good news is that if asthma symptoms are only in relation to viral infection and there is no history of
atopy ,there is a good chance that symptoms will resolve as the child gets older.
If a patient follows physician's advice properly and take medicines regularly,there is more chance of having good asthma control even patient may remain symptoms free without medications.
It is difficult to confirm the diagnosis of asthma during childhood since there is difficulty in preforming objective test.
If I were the treating physician ,I would confirm the diagnosis first by objective test and then advise your son to
>Avoid triggers (eg.dust,cold etc)
>
Steroid inhaher twice daily
>
Bronchodilator (
salbutamol) inhaler as required
>Add other medications according to symptoms control status
So my suggestion is :please consult with a respiratory medicine specialist to perform objective test and confirm the diagnosis.
Hope this helps you.
Wish your son good health.
