No, seriously though, it burns when I breathe. I'm not congested, I don't have any mucus up in there. It just burns when I inhale, I don't smoke, I used to, but haven't in about a year. Even doing like housework and stuff I get out of breath, sometimes just sitting down my breathing get's labored. The closest I could describe it is when you run really really hard, sometimes you get that burning when you breathe? It's like that but all the time. It's been going on for a little less than a week, What the hell?
