I used to think that this pain was just intense heartburn, but now I know it's a spasm of some kind......maybe of my lower esophageal sphincter. It starts hurting in my epigastric area, and shoots through to my back. I used to take rolaids for it, but have learned I just need to swallow something to get it to stop. Does anyone else have this as part of GERD? Curiously enough, I seem to get it very easily, when I drink water. I get this with water, even more than other drinks that you'd think would cause it.
