Question: I have been having shortness of breath a chest pain for the past 2 weeks. I had a pulmonary function test done 1.5 weeks ago and it had some slightly lowered mvv at 75%, a normal mip, and lowered mep with some increases rv. I was told this could be due to poor exertion, which I did give me all, or weakness and and or Neuromuclar issues. Since then the shortness of breath feeling like its hard to talk because I can't get air has been worse and the occasional pain in chest. I've been to the ER and they told me that I was just anxious and sent me home. I additionally have been having on going sinus tachycardia that was diagnosed as possible pots and a month ago had a d-dimer and vq scan which I was told was normal. However, the shortness of breath and difficulty with speaking/ pain didn't happen until 2 weeks ago. Would my pulmonary function test 2 weeks ago have shown a possible pulmonary embolism which could be the cause for these symptoms?
