Effectiveness of Lung after one episode of CAP

Hi all, I had suffered community acquired pneumonia in 2013. From that time, I am regularly taking budamate 200 and then changed to budecort 200 a year before.. If I stop using it, I am getting wheezing sounds in lungs and cough. My questions are:

1) After one episode of pneumonia, will the lung be always affected and cannot return to normal state without permanent use of medicines?

2) Should I take corticosteroid inhaler throughout my life?

Appreciate any opinions. Thanks
