I get white clear cough from the right side of my chest. It also feels inflated sometimes especially when I eat something sour or cold or use earphones. It has been there since a long time now. I once had bronchitis sometime near the end of 2018 and I think it has been there since then. I feel as if a lot of cough is stuck throughout the right side of my food/wind pipe whenever I use ear phones the congestion increases and if I eat something cold or sour occasionally blood comes along with cough otherwise only clear cough comes out but I have to force it alot and sometimes it also pains in my lower right side area of the chest, under the right side ribs also I can breath much less from my right nostril than the lest one and it produces some wizi sound on breathing especially while sleeping.
