Mild Sinus, Turbinate and DNS. Issues.

Hi Doctor, I have issues with nose blockage, runny nose, too much cough even if I swallow I can feel it. Whether it's summer, winter or rainy season. If I come in contact with direct air (somewhat cold) then I used to have a cold. Even if I take a bath with cold water during summer also, it happens. I usually cover my face when I sleep directly under the fan or in front of the cooler even in the AC, I used to have a runny nose. Whenever I woke up in the morning under the fan I used to sneeze. I have had coughs and cold issues since childhood, so not sure exactly how many years I am dealing with. I tried medication multiple times, till I was on medication I felt good then I stopped taking it and again the same issue. I have attached a CT scan report too. Please check let me know how to get rid of all these issues.
