Thanks for your question.
From your question it is evident that you have lower respiratory tract
infection but is it associated with asthma or not that should be understood if you please mention your symptoms like respiratory distress
,wheez etc but it can be a bronchial asthma
and be sure if you are not a smoker that doesnot mean you dont have any chance of bronchial asthma.
So in my opinion you should consult a chest specialist do a chest xray and treat your infection early and after that you should do a pulmonary function test to confirm your diagnosis.
How you are now on Symbicort inhaler?
let me know your future treatment
