I have a rattle in my right lung without cough or cold symptoms. I am unable to clear it as it feels deep in my lung. It comes and goes. Sometimes when I feel it when I breathe I can just shift my body and it will go away. I used to get bronchitis alot when I was younger but have seem to have outgrown it in my adult hood. This feels very different. Like I said no cough, cold or mucus. Just feels like something is stuck down there that pops up once and a while and if I move or shift positions I can make it stop. It is more when I am lying down at night or sitting..I smoked for about a year when I was eighteen but quit. I am 33 years old.

Any Ideas?
