I think I might have post nasal drip, which is causing an extremely strange and nagging cough.  My cough is mostly forced by me because I am feeling like there is phelgm caught in my chest, but then when I try to cough it up I hear a sound like a horn and it is dry.  Sometimes I am just sitting here and the cough happens by itself after I try to take a half way deep breath.  What is this?
