Hi. For about 3 months, I've had a feeling that something is sitting on my chest. I cannot get a full breath out, and I'm always yawning to get that full breath. I don't have any other symptoms of pain, coughing, wheezing, etc. I've had blood work done, a chest X-Ray, an EKG (which showed a left atrial enlargement), and an Echo-cardiogram done. The echo. was done because of the EKG results. Everything turned out fine. I also had sinus surgery done a month ago. I was hoping that was part of my breathing issues, but evidently, it was not as I'm still having a hard time breathing. I've been on Buspar to see if it was anxiety......not helping at all. I've bought essential oils and a diffuser - no change. I did have a lot of stress about 3 months ago (3 funerals in 6 weeks, went back to work, etc.) I don't know if that triggered something or not. I have "another" appt. in 2 days to do other tests.........more money. Just wondering if anyone else had this and what it ended up being.
