I'm a 20 year old male with great overall health, I haven't been sicker than just sniffles since I was a kid. I got this cough maybe 1.5 months ago. It started as just a dry cough but lately I've been coughing phlegm. I was smoking cigs for 2 weeks around the time the phlegm started (2-5 cigs a day) so I think it's fair to say that's what caused the phlegm? Maybe?
Sometimes maybe once a day I'll have pretty bad coughing attacks that make it very difficult to breathe to the point where I am swallowing air, which makes me burp, and wheezing. They usually happen when I am doing something active like running around with my dog or hiking.
I have not seen a doctor because I don't have any health insurance and still believe it might pass but any advice would be great.
