Possible Gastritis?

[Lagaile]

I started having tightness around my upper stomach and back. Then gnawing and burning in mid upper stomach. No vomiting. The gnawing and pain is almost gone. If I move around alot my mid back hurts til I rest awhile. I now have bloating and rumbling stomach. Feels like something is stuck in my left side. I am taking nexium 40 MG. I have yellow diarrhea. I have random single hiccups off and on all day. Going on 3 weeks now. I am having a endoscopy  and colonoscopy done in a few weeks. The anxiety is getting the best of me worrying. Anybody going thru same symptoms? I was told years ago I have dyspepsia,  but this is worse than I felt then and more symptoms.
