So sorry you're having so many problems and not getting results or improvement. I know what you mean with the meds not working. I took Protonix 40mg twice a day, and still had reflux. My reflux caused severe asthma symptoms, so that's why I finally opted for the Nissen Fundoplication surgery, and I'm really glad I did. I'm so much better now! (I also began with reflux during my pregnancy.)
I totally agree with Bill that you need to pursue the basic testing that he listed. That testing can determine your suitability for surgery--although like me, some people don't fit the mold. My reflux wasn't as severe as many people here, but it was enough to set my lungs off and keep them in a constant state of inflammation. Your symptoms are the most telling aspect of your reflux problems. Of course, if you had absolutely no reflux with the PH monitor, they'd probably start looking elsewhere for the solution to your problem. I highly doubt that, though.
Hang in there, girl. You will get help for your problems. You've just got to get through the testing and searches for answers.
Best wishes! This is a great place to find many answers and lots of support.
