Do I have Bronchitis? To cure this.

I am suffering with the problem of cough since long and have been visiting various doctors all through. But I did not get any solution for the same. I doubt whether I have been suffering from Bronchitis (as symptoms). Just for the information, I got cough mostly every morning and the mucus comes out to be thick and white in color. Also when I am unable to breath properly and breathing issue get severe i take "Maxiflo". rotacaps capsules for inhalation. Attached is the latest prescription and medicine i have been advised to take and it gave me some relief but still the issue has not cured fully. Looking forward for any solution or reference for any specialist (Delhi) where I can visit in order to cure this.
