Brief Answer:
Post viral cough

Detailed Answer:
Hello,

This seems to be post-viral cough and can stay for a few weeks. It resolves by itself.
Since you have chronic bronchitis, it may take longer. Did you have anitbiotics and how long you took them? How many episodes of cough do you get in a day?

Antibiotics donot really act against virus but are helpful in earlier recovery for acute infections in chronic bronchitis.
You may try coconut oil gargles twice a day for recovery from cough.
