For a while now it has been feeling like when I breath I can't get enough air or my lungs feel uncomfortable if I try to take a deep breath or even breathe out really far. It feels like my lungs won't expand to accomodate the oxygen or something. It seems like i'm feeling like I can't breathe more than I can breathe normally. When i'm sleeping usually the only comfortable position for me is on my side. I always have to cough too and clear my throat. I know i've read on here about people not being able to breathe when they have panic attacks, but does anyone get it on a daily basis whether you feel anxious or not?
