Thanks for your question on Health Care Magic.
I can understand your situation and problem.
In my opinion, you should
consult pulmonologist and get done PFT (Pulmonary Function Test).
It is must for the diagnosis of
bronchitis.
It will also tell you about severity of the disease.
And treatment of bronchitis is based on severity only.
Main treatment of bronchitis is inhaled treatment
So you may need inhaled bronchodilators and inhaled corticosteroid (ICS).
Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further.
Wish you good health. Thanks.
