Suggest Treatment For Itching Throat And Cough

Hi dr. grief, regarding my throat, I cough when it is cold or breathe cold air, I have become very sensitive to irritants and it itches from top of throat down the sides and I cough. After I finish eating I tend to cough. It used to be a very dry cough, and now it sound as if I had phlegm in my throat. In the last few days I had a bit of pain inside and up my throat but it is gone. I had a very bad dry cough more than a year ago, doctors said it was viral, they gave me albuterol and I improved but the cough has became chronic now I think. I feel as if food stays there in my throat. I noticed that pressing my abdomen at the navel level, will make me cough as if I pushed something up.
