I have had GERD for 3 years now. When was very stressed or had bad anxiety I tended to get pain in my chest which radiated to my back. I had my heart tested. It was OK. When this happened Gaviscon or Slippery Elm did not help at all. I, later realised that this might be the spasm of esophagus. Drinking a glass of very cold water or taking 2.5mg Valium seemed to get rid of it. Does anyone have esophageal spasm pain? What would you do?
