Just read about it on here, someone mentioned it. I've a doctor appointment on Wednesday, yes I know, about time. I had dismissed GERD a year ago cause I don't have heart burn. But I started reading up on it about two weeks ago and found out you don't HAVE to have heart burn, instead I have chest pain and vomiting. But I was afraid the doc would order tests like barium swallow and others. Foolish I know. I was 9 the first time I had that and it was terrible.
