Sorry to hear about what you are going through :( We all can relate, so you've come to the right place! And welcome :)
Have you had an endoscopy? If so, what were the results? What about the pH Bravo capsule test? A lot of us have had that fun manometry :/
I can tell you had I had to go through a few different doctors and do my own research to finally "fix" my problem. You are your biggest advocate and it's smart to educate yourself as much as possible with all of this. This forum is great for that too.
I was scared of surgery but PPI's, diet change and lifestyle change barely took the edge off. I ended up having the LINX surgery and I know I'm only 3 weeks in but it has changed my life. Surgery isn't for everyone but I'm just letting you know what finally helped me :)
