I keep on feeling like I'm short of oxygen. Like I'll stand up and feel like I need to take bigger breaths to get oxygen to my muscles. Then my head will get random pains in it. This doesn't happen everytime I stand, but sometimes.
I also get these sudden feeling that I need to gasp for air, or I'll feel like when I'm swallowing or eating/drinking something I need to take a big breath and I'll get like a shock of panic as I'll feel like I can't (because I am swallowing/drinking) and then I struggle to breathe/swallow for a second.
These things make my panic escalate. I had an oxygen check a couple weeks ago (just the little oximeter thing) and it was ok but I'm just struggling a lot with these symptoms right now.
