Hello. I had an endoscopy to check for problems I MIGHT have w a gastric lapband. The band was not adjusted beforehand. Since then, I have had horrible heartburn and pain. I started taking Omeprazole on the doctors suggestion. I m also diabetic, under control. Could the Omeprazole OR the endoscopy have stirred things up? I am having horrible burning and pain, to the point where I nearly went to the ER 2 days ago. I stopped the pill, which I m taking about a week, and it seems a bit better.
