I suggest that before going to a PPI you see if you can manage with lifestyle changes but also with Tums and Gaviscon if you feel anything (throat, tongue irritation, coughing), to avoid any further irritation If still problematic then first try H2 blocker before PPI. You can ask them to do a biopsy in the next endoscopy if they don't see improvement, or check cancer markers in the blood, but maybe there is no concern if you're treating it early.
