The fact the doctor placed you on courses of prednisolone
and inhalors for these infections indicate that there is a reactive airway component to the infections. In some cases of pneumonia
only antibiotic therapy is needed, however is the the airways are hyperresponisve and there is associated increased mucus production and closure of the airways then prednisolone and inhalors may be needed.
To improve your symptoms you would need to eliminate the factors that could aggravate the asthma or reactive airway such as (1)smoking or exposure, if possible, to second hand smoke (2) treat any associated allergic rhinitis
, determine if there are any specific allergens that you can identify that trigger a response (3) treat any associated GERD
Remember to use the preventer inhalor daily as prescribed, it will help reduce your symptoms and carry the ventolin with you always in case of an attack.
You may need a mucolytic
to help break up the mucus and allow for easier expulsion. Drinking alot of water is also recommended to reduce the thickness of the mucus.
I hope this helps and I hope that you feel better soon
