Observe & prepare safely
Note whether headaches are worse on waking, lying flat or upright; record snoring/sleep quality, jaw clenching, neck symptoms, visual symptoms and how long the morning headache lasts.

Morning or positional headaches with a normal brain MRI: what else can matter?
A normal brain MRI can rule out important structural problems while leaving sleep, blood pressure, dental/bruxism, cervical, migraine or pressure-related mechanisms unresolved. The most useful next step depends on the headache’s timing and positional pattern.
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
Review what type of brain MRI was actually done and what questions it answered; gather blood pressure, sleep and medication information that may not be visible on imaging.
Bring a focused question to a clinician
Ask the appropriate clinician which pattern is most important to test next—sleep-related, dental/bruxism, cervical, migraine, pressure-related or another mechanism—rather than assuming a normal MRI closes the case.
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.
