GERD: I see you're treated for GERD and have taken Nexium/Esomeprazole. At 29, your risk for heart disease is exceptionally low. Your symptoms are very strongly suggestive of acid reflux with esophagitis and/or gastritis/or dyspepsia. Have you been checked for H. pylori? Barrett's Esophagus? You need more testing to find out why your symptoms are so severe.
