41 year old female. non smoker (ex smoker) , healthy weight and diet. 10+year history of reflux disease. Currently on 40mg of protonix for about 2.5 years. Ppi definitely decreased the severe symptoms of globus, regurgitation and upper epigastric pain was having. The last couple weeks I have had some weird symptoms. Sore throat on and off for a week without a cold. Now the last two days, the troubling symptom started in the middle of the night two days ago. When I eat certain foods (anything that is harder than soup, or is not liquid or really soft). I chew the food and swallow it. I complete the swallow fine with no issues, but IMMEDIATELY after the swallow finishes, there is a rebound pain in the lower part of my throat. Almost as if it's that food passing through and touches that spot in my throat. It is gone as quickly as it comes. It's not every time, or every food. I am terrified. I have no actual trouble swallowing, just the pain about 70% of the time. I have a great deal of lifelong anxiety surrounding my throat, and I've been reading a lot about throat cancer. Is it possible my Ppi has stopped working?

I should also add that the last week or so, I have the feeling of globus back again, unrelated to eating and only on and off. The swallowing pain I described above though is absent all other times.
