Hi,
I'm in a pretty similar situation. I do have LPR and gastritis both
I have the burning pretty much constant, in my stomach up to my neck, and mouth even. It doesn't matter if I eat nothing or something, or do meds or no meds. Actually the meds helped a little, but not enough and the side effects were not fun, so am trying other things.
Are you taking any meds at all? And are you taking any
vitamins? The interesting thing, I stopped taking all vitamins that were tablets (hard, not capsules) and have been noting that I feel a little better...Just a thought. i think that sometimes we forget about those things, and they can be hard on the stomach.
Just a thought I wanted to throw out there.
Oh have you tried Gaviscon? That does help me a little with the burning.
I hope you get some relief soon, at least you know it's not an ulcer or something serious.
