Tired of being bloated and in pain, someone please help

[Melissa6204]

History:I have had GERD since about 2009, I was treating it with Prilosec, over the years I have had my dosage increased, increased again, then told to start taking it twice a day, now they have switched me to Nexium.  In 2013 I had trouble swallowing food-bread was the worst.  I had an endoscopy and they found chronic gastritis, abnormal mucosa and esophaegeal stricture, which they dilated, 6 months later I had to have it dilated again.

Current problem:  I still have heartburn and indigestion, but since October, I have been having a pain in my stomach right in the  top center, it's a stabbing pain.  I am also bloated from about an hour after I wake up until I go to bed.  I have an intense pressure/tension feeling in my stomach as though I just did 200 sit ups, but it is a constant feeling.  This is very embarassing, but I cannot stop burping either, I cannot even go 20 minutes without burping.

I went to the doctor in October, he thought it was gallstones, I had an ultrasound of the galbladder, liver & pancreas, everything was normal.  Blood tests were normal other than one time I had a high blood count, but it went back to normal when it was rechecked.  I have had low vitamin B12 and D for the last 2 years.  I went back to the doctor in February, they changed my medication and said it was a gastritis flare up, well I have had gastritis for a while and never had these additional symptoms, just the same ones I had for GERD.  The new medicine is not helping any and I am miserable.  I hate to wake up in the morning because I am constantly in pain and uncomfortable and I hate going to work because of the burping and how I feel.  I am out of breath all of the time.

I tried a 2 week eliminate all fats diet, I tried 2 weeks with no dairy, 2 weeks with no sugar.  I take vitamins and probiotics.  Any suggestions would be greatly appreciated, thank you!
