Hello
You were having bacterial
bronchitis ( as in query ) and took ,
steroid , antibiotics ,
codeine & inhaler.
Still
cough present with whistling sound during expiration .
This indicate that you are having asthmatic allergic bronchitis ( asthma ).
When such patient visit my clinic I only prescribe montelukast+bambuterol tablet once or twice in day and patient respond on day one .
I don't like to prescribe STROID , CODEINE ,& ANTIBIOTICS & INHALERS .
Hot coffee and steam inhalation provide much needed relief in every case .
If you don't respond this treatment then consult a pulmonologist and get his opinion .
Avoid dust , mite , pollen , mold , pests ( cockroaches )
smoking ( active & passive ) sudden change in temperature ( increase or decrease) , fumes , powder , as these are predisposing factors for such symptoms.
Good luck.
