So sorry to hear about
your difficulties. There are lots of people here who can relate to your experiences with GERD. My symptoms weren't like yours, but I've read many posts that describe similar experiences. I can identify with the Maalox--that has always been my most soothing medication. Even now, 5 months post surgery, when my wrap is irritated (it's still healing) I love my Maalox!
It really sounds like you need to get to a GI doc if you can. I know insurance is a problem for many people, but if you can manage it, I think a GI doc could get to the bottom of your problems and give you lots of help. Anxiety is also very common with uncontrolled GERD symptoms.
Be sure to continue to post here. Ask as many questions as you like, and members here will do their best to offer you support and information.
You're in a good place--people here really understand what you're going through.
Hang in there. You'll find relief.
Best wishes! We're here for you!
