Why Do My Tests Come Back Normal When I Still Have Symptoms?
By Dr. Rusty Lavender, D.C. — upper cervical chiropractor, Lavender Family Chiropractic, Sarasota, FL. Reviewed and updated October 2026.
Our complete guide to upper cervical chiropractic care in Sarasota explains what the top two vertebrae control, how we measure them with 3D imaging, and what a correction feels like.
In short: A normal test result means the test did not find what it was designed to find. It does not mean nothing is wrong, and it does not mean the symptom is imagined. Brain MRI, blood work, hearing tests, EKGs, and neck MRIs each look at a specific set of structures, and not one of them measures the alignment of the atlas (C1) and axis (C2) under the skull. For dizziness, headaches, neck pain, ear pressure, brain fog, and the racing-heart symptoms that often travel with them, that is the piece that goes unmeasured. This page explains what each test can and cannot see, what “normal” rules out, and what we measure at Lavender Family Chiropractic in Sarasota. Call (941) 243-3729.
First, the good news in a normal result
If you have had a brain MRI, a cervical MRI, a full blood panel, and a cardiac workup and all of them came back normal, the serious things have been looked for. Tumor, stroke, multiple sclerosis, a bleed, a structural heart problem, thyroid disease, anemia, infection: those are the reasons your physician ordered the tests, and a clean set of results is a real answer to a real question. We never want a patient to read this page and skip that step. A new, severe, or changing headache, a sudden loss of hearing, weakness, numbness, confusion, trouble speaking, chest pain, or fainting belongs in a physician’s hands first, every time.
The frustration starts afterward, when the symptom that sent you for testing is still there and the conversation ends with “everything looks fine.” Normal is not the same as explained. The question to ask is not “what did the tests find?” but “what were the tests looking at?”
What each test actually measures
| Test | What it is designed to find | What it does not measure |
|---|---|---|
| Brain MRI | Tumor, stroke, demyelination, bleeding, structural brain abnormalities, Chiari malformation | The position of the atlas and axis under the skull; how the neck behaves upright and in motion |
| Cervical (neck) MRI | Disc herniation, spinal cord compression, stenosis, ligament tears when specifically protocolled | Rotation and tilt of C1 relative to the skull and C2; it is read for tissue, lying flat, and reported on what was ordered |
| CT of the head or neck | Fracture, acute bleeding, bony abnormality | Fine alignment of the upper cervical joints unless specifically measured; usually taken supine |
| Hearing test, VNG, caloric testing | Inner ear and vestibular nerve function | Dizziness arising from neck proprioceptors, which feed the same balance centers |
| Blood work | Thyroid, anemia, B12, inflammation markers, infection, metabolic causes | Anything mechanical or neurological in origin |
| EKG, Holter, echocardiogram | Rhythm problems, structural heart disease | Autonomic nervous system regulation driven from the brainstem and upper neck |
| Upper cervical examination with 3D CBCT and thermography (Lavender Family Chiropractic, Sarasota) | Position of the atlas and axis in three planes; side-to-side autonomic regulation along the spine | Disease. We do not diagnose tumors, strokes, or inner ear disease, and we rely on your physician’s workup to have excluded them |
Read down the right-hand column and a pattern appears. Every standard test is built to find disease in a specific organ. None is built to measure the alignment and function of the top of the neck. So when the problem is there, every test comes back normal, honestly and correctly, and the symptom persists.
Why the top of the neck escapes every workup
The atlas carries the skull and surrounds the brainstem. The nerves from the top three cervical segments converge in the upper spinal cord with the trigeminal nerve, which is why a problem at C1 and C2 can show up as a headache behind the eye, pressure in the ear, pain at the base of the skull, or facial symptoms rather than as neck pain. The small muscles and joints at the top of the neck are also packed with proprioceptors, the position sensors the brain uses, together with the eyes and the inner ear, to know where the head is in space. A 2022 narrative review in the Journal of Clinical Medicine describes how the cervical spine’s highly developed proprioceptive receptors are integrated with the visual and vestibular systems, and how a mismatch in that input produces cervicogenic dizziness, with diagnosis resting on clinical features, specific tests such as the cervical torsion test, and exclusion of other causes. A 2017 paper in Archives of Physiotherapy makes the same point from the diagnostic side: there is no definitive laboratory test for cervicogenic dizziness, so it is a diagnosis of exclusion that requires a high level of skill to separate from vestibular, medical, and vascular causes. In plain terms, the standard workup is designed to rule those other causes out; it is not designed to rule the neck in. A 2009 paper in the Journal of Orthopaedic and Sports Physical Therapy adds the clinical consequence: altered input from the cervical position sensors disturbs postural stability and head and eye movement control, and can maintain or progress symptoms in people with neck involvement even when conventional treatment has been tried.
The same logic applies to headache. A 2024 review in Best Practice and Research: Clinical Rheumatology describes cervicogenic headache as a one-sided headache that starts in the neck and radiates forward, often with nausea and light sensitivity that lead it to be mistaken for migraine. A brain MRI in that patient is normal because the brain is not the problem.
Why a normal MRI does not settle the alignment question
This is the single most common point of confusion we untangle in Sarasota. Patients assume “my MRI was normal” means “my neck is aligned.” MRI is read for tissue, taken lying down, and reported on the structures the ordering physician asked about. The rotational and lateral position of the atlas under the skull is not what the study is for, and the radiologist is not asked to measure it. A 3D cone beam CT is a bone study, taken with the head in position, and measuring that alignment is exactly what it does. The two answer different questions, which is why a normal MRI and a measurable atlas misalignment are routinely found in the same person. Our 3D CBCT page explains what the scan shows, what it does not, and how its radiation dose compares. If you were told you might have ligament laxity rather than a simple misalignment, our guide to how craniocervical instability is diagnosed covers the upright imaging that applies.
The symptoms that most often arrive with a folder of normal results
Over years of practice in Sarasota, the same handful of presentations arrive with the same story. Dizziness and imbalance with normal ear tests and a normal brain MRI, often worse turning the head or in busy visual environments. Headaches at the base of the skull or behind one eye with a normal MRI, labeled migraine or tension-type, that medication dulls without changing. Ear fullness and pressure with a normal ENT exam and normal hearing. Racing heart, lightheadedness on standing, and exercise intolerance with a normal cardiac workup. Brain fog and fatigue with normal blood work. And very often, a neck injury in the history, sometimes years earlier, that nobody connected to the symptom because the neck was never the complaint. A 2023 narrative review in Brain and NeuroRehabilitation describes exactly this picture after concussion and whiplash: dizziness, headache, neck pain, visual complaints, and anxiety, a proper medical workup that may remain inconclusive, and damage to the cervical proprioceptive, vestibular, and ocular systems that together control posture.
None of these is proof of an upper cervical problem. Each is a reason to measure.
What we measure when your tests are normal
At Lavender Family Chiropractic the evaluation starts with your records. We read your MRI reports, your blood work, and your specialist letters, because a clean workup is the foundation we build on, not something we repeat. Then we measure what those tests did not: a consultation and history that goes back to the first symptom and every neck injury since; a neurological and orthopedic examination of the upper neck, including balance and head-position testing; paraspinal infrared thermography, which reads side-to-side autonomic regulation along the spine with no radiation; and, when the examination points to the upper neck, 3D CBCT imaging of the atlas and axis. If the atlas is misaligned, the Knee Chest correction is calculated from that image and delivered with low force and no twisting of the neck, and thermography afterward confirms the nervous system responded. Results vary by person; we measure before and after. If the upper neck is not involved, we say so and point you to the provider who fits. Our what to expect page walks through each step.
Two companion guides pick up where this one leaves off: why you are being told it is all in your head, and why no one can tell you what is wrong.

Common questions when tests come back normal
If my MRI is normal, can my neck still be the problem? Yes. MRI is read for tissue and taken lying down; it is not asked to measure the rotation or tilt of the atlas under the skull. A normal MRI rules out the serious causes it was ordered for and leaves the alignment question open.
Should I stop seeing my physician if the tests are normal? No. Keep your physician, your neurologist, or your ENT. We work alongside them, read their reports, and send ours back. A normal workup is what makes an upper cervical evaluation appropriate, not a replacement for it.
What symptoms most often come with normal tests? Dizziness and imbalance with normal ear tests, headaches at the base of the skull or behind one eye with a normal MRI, ear pressure with a normal ENT exam, racing heart and lightheadedness with a normal cardiac workup, and brain fog with normal blood work, often with a neck injury somewhere in the history.
What do you measure that the tests did not? The position of the atlas and axis in three planes with 3D CBCT, and side-to-side autonomic regulation along the spine with infrared thermography, alongside a neurological and orthopedic examination of the upper neck.
What if your evaluation is also normal? Then we tell you that plainly and point you to the provider most likely to help. An honest no is part of the service.
