Hello doctors, two or three days ago, I noticed that I had to gasp to take a deep breath, which would result in either a complete or an incomplete yawning. I asked a free question and the doctors told me it was air hunger and it was because of stress. It did seem plausible, as I underwent a stressful event the night before experiencing these symptoms. But, now, I am sure Im unable to breathe properly. I try to breathe and it feels like Im only taking in 50% of what I was able to. I try to take a deep breath and Im simply unable to. I have to force myself for 4-5 breaths, after which I can finally take a single deep breath, and then it returns to the "barely able to breath" situation. No cough, or pain in chest. I do have some mucus, but I've struggled with more mucus before and never felt this way. My Noise watch says my blood oxygen is 98%. Please advise.
