Thanks for wriiting your query.
I would suggest that you should get properly investiigated.
You should get following investigations done :-
1. X-Ray of your chest (PA view).
2. Complete Blood Count
3. Sputum examination.
Also get your chest auscultated and if needed bronchodilators can be added.
You can take antihistaminic like fenofexadine
120 mg once a day for relief of cough
I hope this is helpful to you.
