Thank you for the reply.
If I take puff regularly, I do not have any problems. But, if I do not take it, there is breathing difficulty. Two years ago, I was hospitalized due to shortness of breath and got discharged after two days. There is no weight loss or fever. I am fit, and my health is good.
I took a blood test six months before, and the report was normal with borderline blood sugar. And now it is in control.
The cough is only from the throat, and there is no chest congestion for which I am not taking any syrup or medication. Instead, I get some relief by gargling with saltwater.
