i have all the symptoms you mentioned. I am going nuts trying to figure out whats going on. But i get nasal inflammation and congestion, either the right or left nostril will get completely or almost completely blocked, especially when I lay down. I have no idea if this is a result of acid reflux or not. I use to get heart palps but they have gone away for the most part thank God. I now have incredible twitching/spasms and a bunch of other stuff.
I never burp and bring up acid or taste the sour acid, so i dont even know if i have acid reflux or not, but i was diagnosed with it last year.
Im at the point where i dont know if the twitching and sinus/nose mucus and inflammation problems are caused by acid reflux or side effects by PPI/acid reflux meRAB, OR if i got sum kind of virus.
i totally understand what you are going through and I know exactly how you feel. I also get extreme bouts of lightheadedness where i feel almost like im going to pass out, i was thinking that might be from acid reflux "fumes" or sumthing, i dunno.
Its all just theories.
