I was recently diagnosed with GERD and am on 40 mg Nexium twice a day. However, I am also very fatigued, constantly cold, and have both nausea and stomach cramping (which the Nexium has helped somewhat). I can only eat small meals as I get full very quickly. My doctor suggested a HideScan but he doesn't know what to make with my constant coldness and fatigue. Does anyone else have these symptoms? Thanks.
