Hi there ...
Thank you for the question ...
As you have Chronic cough that is of more than 2 months duration , not responding to antibiotics / and other measures .
You have no fever , but much pronounced S.O.B at this stage it would be ideal for you to have few test to see the exacu cause of cough .
I will suggest you to have Chest X ray PA view to look what is going in lungs , in addition to that you should have Blood CP along with ESR to see cell count and to look for infection .
Treatment depends on exact diagnosis , test will help you out to reach the final conclusion .
Please get test as early as possible and consult Pulmonologist ( Dr who deals with chest medicine ).
Please proceed as I advised you .
Regards ***** ***** luck .
