Acid Reflux HELP PLEASE 😢

Ashley
I am in so much pain EVERYDAY because of acid reflux. I have cut out citrus, greasy food, and spicy food, but no matter what I eat these days I get it. Zantac doesn't work anymore and tums don't work. I get it so bad that it makes me throw up and prevents me from sleeping. I get so nauseous that I have to take the anti nausea meds I had in my first trimester. It also hurts when I breathe, I literally feel like I'm dying.
 I went into L&D to be evaluated because I literally couldn't do anything without being in excruciating pain and they just gave me a GI cocktail that did not work. So my guess is that the baby is pushing on something to create it. But I'm worried because nothing is working and if I have it during labor I'm not going to be able to breathe. 
I'm contemplating calling the 24 hour nurse again to see what she says but I'm not sure what to do... Help pleaseÂ
