I Had A Partial Gastrectomy 8 Years Ago. I Suffer

I had a partial gastrectomy 8 years ago. I suffer with terrible eosinphiloc esophageal and gastritis. My dr, performed an EGD last week and he still sees a large amt. Of acid and or bile. He prescibed xifaxan to passibly help get rid of the bad bacteria. Today i noticed my tongue has a milky film on it and my heartburn is so bad that I vomit. I would like to know I possibly have thrush
