Gerd Symptoms

I have GERD and regular GERD symptoms, along with some unusual symptoms my ENT and I seem to agree is caused by, including temporary ear pain and sinus pain, throat clearing, bitter taste in the mouth, and an indescribable, I can just smell a pungent odor . Can smell HCl acid? HCl smoking? Esophageal scarring? It's the same smell, so I do not think the stomach contents. It certainly improves a bit with H2 blockers and reversible with antacids, but is usually on and off all day, every day. Sinuses are clean, uninflamed, infected. I am in excellent health, although GERD. Any help would be greatly appreciated, thanks.
