Do you get phlegm after you eat as well, or is it just a heartburn type feeling? I bring up food sometimes 15 minutes after eating and have horrible upper stomach and chest discomfort if I lay down, but I also have phlegm every time I eat, unless it is something really small. I tried to look online but am not finding that phlegm is a symptom of GERD. Does anyone else experience this, because I know that it can be a symptom of *LS. It has been going on for a month now.
