No I have never smoked..And that is why I am so puzzled about
this..If I was sick a lot I might could understand but I feel fine most of the time and do not have a cold or any sinus problems. But the rattle that I feel is mostly nerve racking and worries me a lot. I have had a few people in my family die with lung cancer. I don't know if i should start with a regular MD or go to a lung DR.
