Re: Help Please... I am so worried
An Endoscopy is a good idea .
It's possible you might have a Hiatal-Hernia. I have one and you can suffer a lot with belching and also a feeling that your food is regurgitating.
I wish you well with the Endoscopy, they are nothing to fear, you will be sedated and wont know about it.
Acid Reflux and PND often go together.
