I have been taking Prevacid for 3 years. I had an endoscopy last month and still have slight irritation. I follow most of the rules and have my bed raised. I know when I eat chocolate and the other offenders, it acts up. However, even when I am eating correctly sometimes I get a lot of burping...nothing comes up but the pain is worse in my upper back between the shoulder blades. When I burp it improves so I am almost sure it's from gas. I also get the gas pains in my face and jaw. SO uncomfortable. I'd like to know if anyone else gets this awful back pain and what you do for it and if you are on any medications, if so, which one. Thanks.
