How can I tell if I have LPR or Gerd? I went to my Dr because I had nausea and vomited a few times started PPIs but 11 days in and now I think food is sticking in my right side throat. Can gastroscopy clarify what type of reflux it is? Some of my original symptoms are gone but I hate the constant urge to swallow saliva and the sensation (or even reality) of food being stuck only in the right side where when I experience burning pain is always there. Help me
