Ok, so about a week ago I went to the ER with stomach pains, nausea, and vomiting, tested me for h pylori and it came out negative I've been in and out of the hospital/doctors office for about a week with no results one of my doctors said I came out positive with an irritated stomach I get these bad pains in the middle of my abdomen right below my chest and it burns I don't have any more nausea nor am I vomiting I just have the pain and I find that I burp a lot! They prescribed me omeprazole 20 mg and Zantac 150 I find that its helping a little bit but then again I've only been taking them for 2 going on 3 days how long till the pain goes away? Do I have have gastritis or an ulcer? Am I on the right meds? Should i relax and give the meds some time? I have really bad anxiety and I'm looking for some answers, please anything helps.
