Hello @jamierb and welcome to Mayo Connect. I am sorry to hear of all of these uncomfortable symptoms that you are experiencing without any resolution to the problem. Many on Connect, myself included, have dealt with hard-to-diagnose health issues and I know how frustrating it can be.

We have other discussion groups on Connect similar to your situation. Here are the links to those discussions, https://connect.mayoclinic.org/discussion/mayo-rochester-gi-dr-recommendations/ and https://connect.mayoclinic.org/discussion/chronic-digestive-disorders/

You have had a number of tests. Have these included a look at your gall bladder? Are there any swallowing issues? Did the certified dietician mention trying a low Fodmap diet? This has been helpful for some people who have issues like yours.

Finally, have you considered a second opinion at a university medical center or at a facility like Mayo Clinic? These health centers are research-oriented and have a multidisciplinary approach. This might be helpful to you as you are understandably concerned about this wide variety of symptoms that you feel are not typical of GERD. If you would like a consultation at one of Mayo Clinic's three facilities here is a link to appointment information, http://mayocl.in/1mtmR63.

I hope you find some resolution to these symptoms. Will you post again with an update?
