I went for the screening for this inhaler study and didn't qualify as my breathing wasn't good enough. It's ok, there are several more studies coming up in November. I did get to see my pulmonologist and he is going to set up my apt. with the cardiologist for and echo and stress test. I will also go back to my gastroenterologist and have more tests. He had prescrbied nexium for me which worked the best but my insurance won't pay for it. I hope to see some improvement now that I am done smoking but gerd is dangerous and can cause cancer in the esophagus. I hope very soon I will be able to get on here with good news only!
