My chest has a tight / heavy / cramping sensation. The pain seems to be in my back as well. I had a nuclear stress test on my heart and they say its not my heart causing the chest pain. I also had an endoscopy which has discovered I have Erosive Esophagitis. My pulmonologist seems to believe its possible the Erosive Esophagitis is causing some of the chest pain. But Im having a hard time believing this tight heavy sensation I have in my chest is from Erosive Esophagitis. Has anyone here evere had this type of a problem? Is chest tightness common to people with Emphysema? Does anyone have any idea whether or not Erosive Esophagitis could be causing my chest problems?
