Did you symptoms just come in the last several months?
Your story kind of reminds me of mine.
I initially had a chest tightness like a hard time taking a deep breath.
Went of PPIs, it helped but my throat got sore, then I got a burning chest, then throat, then mouth.
I believe that is a form of LPR which is GERD.
Continue your treatment as instructed by your GI. But don't worry, you are not alone in this. I just had a Lap Nissen today. Overall I'm happy with the surgery and will embrace the recovery.
I hope you feel better.
