Among other problems I've had awful breathing issues for almost a year.
I've seen every specialist under the sun about my problems and I am currently being told I have some sort of neurological disorder.
However, over the past few months I've become increasingly aware that breathing through my nose has become more and more difficult, to the point that my body goes into full-on stress mode when it cant ger enough oxygen whilst breathing that way.
It's beginning to seem like it may be the underlying issue, as I breathe through my mouth a LOT, which is only meant to be the back up and I'm thinking I may have actually changed the way I breathe because of it which has causes these problems.
Just wanted to add - I don't know what post-nasal drip feels like, but I often get clear liquid running out of my nose, stop breathing when I'm really tired and falling asleep. My sinuses feel very tight and constricted, almost like they're being squeezed. But no pain that I've noticed at all.
