Observe & prepare safely
Note timing between meals and burning, whether symptoms are acid-like or regurgitation/throat symptoms, and whether position or specific foods consistently change them.

Reflux symptoms with a normal endoscopy and poor PPI response: what is worth clarifying?
A normal endoscopy does not by itself tell you whether symptoms are caused by acid reflux, non-acid reflux, esophageal sensitivity, eosinophilic inflammation, motility or another mechanism. The goal is to identify which unanswered question matters next rather than simply escalating treatment.
This page is general research orientation. It cannot diagnose you or determine that it is safe to delay medical care.
Initial research compass
Three ways to make the next step more informative.
Audit records & evidence
Retrieve the endoscopy and pathology report, including whether esophageal biopsies were taken and what treatment dose/timing was actually tried.
Bring a focused question to a clinician
Ask gastroenterology whether the next useful discriminator is reflux monitoring, review for eosinophilic esophagitis, motility assessment or another explanation rather than simply escalating acid suppression.
Important: these are research-orientation ideas, not instructions to self-diagnose, stop prescribed treatment, or perform unsafe home testing. If symptoms may be urgent, seek appropriate in-person care first.
Why a deeper interview can help
A short web page cannot reconstruct a longitudinal medical case.
A full WhatDx case can ask follow-up questions based on your answers, review the records you upload, reconstruct chronology, track treatment response and compare competing explanations across specialties. It then produces a research dossier that you can discuss with a clinician.
The free suitability check is the right next step if you want a case-specific answer about whether that process is likely to add value.

Before you use this guide.
Is this page telling me what condition I have?
No. The same symptom pattern can have many causes, and this page does not have your full history, examination or records. It is intended to organize useful questions, not name a diagnosis.
What if my previous tests were “normal”?
Normal results can be genuinely reassuring, but their meaning depends on what was tested, when it was tested and which question the test can actually answer. A research process can help map that context without assuming that “normal” means “nothing is wrong.”
What does the paid WhatDx session provide?
A detailed adaptive interview, record review, a persistent 90-day case state and an evidence-linked research dossier. It is research support, not prescribing or treatment.
