Good morning. Sorry you’re having to deal with this. It’s so weird that we can have the same condition or disease and have similar or very different symptoms. I have esophagitis as well as some other health issues. And I had a pft done at my pulmonologist and it was abnormal. My dr feels it can definitely be from Gerd. He’s also sending me to an ent to be thorough. Have you had a pft done yet?
