Any of you ever feel short of breath AFTER quitting smoking? I actually noticed myself getting shorter of breath, even at rest back in November which culminated in my going to the ER in December. Thought I was possibly having heart attack which I wasn't. No congestive heart failure, chest x-ray looked ok, blood tests good. Since then have tested ok on basic spirometry test for copd/asthma. I haven't smoked since I went to the ER. Frustrating trying to figure this out.

I do have inflamed nasal passages/possibly sinuses which could be a remnant of the smoking or something else. I know smoking sometimes masks other conditions and when you quit they come out. Of course I started having the shortness of breath before I quit. I've never had allergies but of course they can develop later in life.

So have any of you noticed shortness of breath after quitting? I've read online that some people have and just curious. I haven't seemed to cough or hack up a lot of phlegm since quitting like some people do. Maybe everything is still stuck and need to get it moving out.
