This constant stomach burning...

I was diagnosed with stomach erosion , esophagus erosion and acid reflux after an endoscopy but I never get heartburn.
After every meal I eat regardless of what it is I have this constant stomach burning that can get really bad. I'm waiting for an appointment with a new gastro but I'm worried about this.

All my lower abdomen constantly feels like it's on fire and this all started after a course of Antibiotics , it tends to get very bad at night time.

I'm debating on what could be wrong with me , gastritis , low stomach acid , bile reflux , candida causing all of this , who knows !?.

All I do know if that a carb free diet didn't help me much and since reintroducing more of them I've felt better.
I've started to eat more foods for my liver like beets ( going to try beet juice soon also ) and am only ever drinking water and my diet couldn't be better.

It just seems as if my stomach continues to burn constantly, any ideas ?.
