I get cough almost every month. I cannot breathe properly. How can I overcome these problems?

Hello doctor,

I am an electrical engineering student. My age is 21 years. I have been facing some problems in the last five years. When I get a cough, I feel uneasy, and this problem is there throughout the year. If I do not take any medicine, water comes out of my nose and irritates me. I consulted many doctors. They advised cough syrups. One doctor advised taking a syrup that contains Ambroxol. Another doctor advised taking a syrup that contains Guaifenesin + Pseudoephedrine + Triprolidine HCl. When I get cold, I take this medicine. I want to know why do I have a cough periodically.

When I take a bath in cold water, I cannot breathe properly. So, I always use hot water for bathing. I consulted a local doctor to solve this problem. But, he advised me to take a bath in cold water and said that it was not a problem. This also worsened my cough. How do I reduce it?

I cannot travel by regular bus. When the bus window is opened, the outside air circulates, and if the air flows through my mouth, my mouth becomes dry, and I cannot breathe. So, I always travel by air-conditioned buses in which the windows stay closed.

How can I overcome these problems? Please help.
