Thank you so much for posting. I’ve had an issue of not feeling like I got enough oxygen when I breathe deeply and all tests show normal. The desire to yawn a lot hit me. I run a group and hated yawning as they were talking but needed to. Eventually, I had to let them know I was struggling quite a bit. Anxiety clearly made it worse but I fainted playing tennis because I couldn’t get a breath and became dizzy 5 minutes into playing when I typically play 2 hours. Drs seem to think it’s anxiety, which I figured they would but I feel I am very aware when my anxiety is causing physical symptoms. I changed my diet completely and meditate daily as well as yoga. I feel like it’s all in my gut for some reason. X-rays show excessive gas but I had that issue since I was a toddler. I notice I breathe better laying down with something under my lower back.
Sorry for the rant, you just posted the closest thing I’ve heard to what I am experiencing. I’m hoping it’s something that isn’t just there. I’m a healthy 30 year old. It just feels like something that doesn’t have to be permanent.
