I finally got scared enough about the chest pains that wouldn't go away and went to the ER yesterday afternoon. I told them I had been told to ask about this test and the dr. asked if I knew some doctors or something...just told him I had some knowledgeable friends (thanks everyone). Anyhow after talking with me he seemed to be concerned about the possibility of PE and ordered the d-Dimer. It came back "high" and so then I had a chest x-ray and then a CT scan of my chest. I'm happy to report that those came back negative. I'm happy that a serious medical condition like PE has been ruled out but I'm still wondering why I continue to have these chest pains. He still wants me to have the stress test on Tue. He's starting to think that it may be gastric and gave me an Rx. I'll try that and see how it goes.
