Lung problems

Anyone have any experience/advice? I know y'all aren't doctors (not looking for a diagnosis) but I'm afraid to google and dh is being a butt.

Has anyone ever felt like they can't breathe too deeply or you'll have discomfort and/or a coughing fit? It's been getting worse lately.

I'll notice it happens when cleaning and/or if I'm too hot. I also get winded easily.

If I do breathe too deeply I'll cough (wet cough) and then feel wheezy or light headed for a bit afterwards.

I don't think it's just a cough because I've noticed it before, it's just been more apparent lately.

Any help is greatly appreciated!
