Hey aberleytrei91,
I have had that on and off scratchy throat from GERD off and on for years. I tried a
gluten free diet and my GERD went away. I have stopped taking my proton pump inhibitors for awhile now. I would suggest to stop carbonated sodas, caffeine, alcohol, citrus, dairy, tomatoes, peppers and potatoes and gluten for 1 week. Then reintroduce only gluten products for a day or two and see how you feel. Continue your PPI during this time. If your symptoms come back it is gluten.
