Headaches are one of the most common health complaints in the United States — and one of the most under-treated. Not because there are no options, but because most of the available options focus on managing the symptom rather than finding out why the headache keeps happening in the first place.
If you have been dealing with recurring headaches in Jacksonville or Mandarin — whether they are daily tension headaches, debilitating migraines, morning headaches that wake you up, or pressure headaches that build through the day — this page is worth reading before you reach for another ibuprofen or book another neurology appointment.
At San Jose Chiropractic in the Mandarin area of Jacksonville, Dr. Thuraia Owais (Dr. O) specializes in evaluating and correcting upper cervical misalignment — one of the most significant and most consistently overlooked structural contributors to chronic headaches. Her approach is precise, gentle, and built around understanding what is actually driving your specific headache pattern rather than suppressing it with medication.
Understanding Headaches: Not All Head Pain Is the Same
Why Headache Type Matters for Treatment
Headache is a symptom, not a diagnosis. It is the brain's response to a wide range of possible triggers, and the type of headache a person experiences reflects the underlying mechanism producing it. The most common headache types seen at San Jose Chiropractic include:
Tension-Type Headaches
Tension headaches are the most common type of primary headache. They are typically described as a dull, aching, pressure-like pain that wraps around the head — often described as a tight band or vice around the skull. They frequently involve tightness or tenderness in the neck, shoulders, and scalp muscles.
Tension headaches can be episodic or chronic, and they are strongly associated with sustained muscle contraction, poor posture, forward head position, and spinal misalignment in the upper cervical region.
Cervicogenic Headaches
Cervicogenic headaches originate directly from the cervical spine — specifically from the upper cervical joints, muscles, and nerves. They typically present as a unilateral headache that begins in the neck or base of the skull and refers upward into the head, often toward the eye or temple on the same side.
Cervicogenic headaches are frequently misdiagnosed as tension headaches or migraines because the head pain is the presenting symptom rather than the neck pain that is causing it. Upper cervical evaluation is essential for this headache type, and it is where chiropractic care has the strongest and most direct clinical rationale.
Migraine
Migraine is a neurological condition involving complex changes in brainstem activity, nerve sensitization, and vascular regulation. It produces moderate to severe head pain, typically unilateral and throbbing, accompanied by nausea, light sensitivity, sound sensitivity, and in some cases visual aura.
The upper cervical spine has a well-established relationship with migraine physiology through the trigeminal nucleus caudalis — the brainstem structure that processes migraine pain — which extends into the upper cervical spinal cord.

Post-Concussion Headaches
Headaches are one of the most common and persistent symptoms following a concussion or mild traumatic brain injury. Post-concussion headaches often resemble migraines or tension headaches and can persist for weeks, months, or even years after the initial injury.
Because concussions and head injuries frequently involve upper cervical trauma — even when the neck appears uninjured externally — upper cervical misalignment is a common and significant contributor to post-concussion headache persistence. If your headaches began or worsened after a head injury, fall, or car accident, upper cervical evaluation should be a priority.
Cluster Headaches
Cluster headaches are a rare but extremely severe headache type characterized by intense, unilateral pain around or behind one eye, often accompanied by tearing, nasal congestion, and restlessness. They occur in clusters — daily or multiple times daily for weeks or months — followed by remission periods.
While cluster headaches are primarily a neurological condition, upper cervical dysfunction can influence the hypothalamic and autonomic pathways involved in their occurrence and may be a contributing factor worth evaluating.
Morning Headaches and Sleep-Related Headaches
Headaches that are present upon waking or develop in the early morning hours are a distinct presentation that warrants specific attention. Common causes include sleep position stress on the cervical spine, sustained upper cervical misalignment that increases muscle tension overnight, bruxism (teeth grinding) linked to upper cervical dysfunction, and in some cases, sleep apnea-related oxygen changes.
Upper cervical evaluation is particularly valuable for patients whose headaches are consistently worse in the morning.
Tech Neck and Postural Headaches
Extended screen time, forward head posture, and prolonged desk work create sustained mechanical stress on the upper cervical spine that accumulates over time. For every inch the head moves forward from its neutral position over the shoulders, the effective load on the cervical spine increases significantly.
This creates chronic muscle fatigue, joint compression, and nerve irritation that manifests as end-of-day headaches, pressure behind the eyes, and base-of-skull tension. This presentation is extremely common in Jacksonville's working population and one of the most responsive to upper cervical correction.
The Atlas, the Brainstem, and the Headache Connection
The Atlas (C1) and Axis (C2) are the top two vertebrae in the neck, sitting directly beneath the brainstem at the craniocervical junction. This region is unique in the spine for several reasons that make it particularly relevant to headache physiology.
The trigeminal nucleus caudalis. This brainstem structure is the primary pain processing center for headaches of all types. It extends from the brainstem down into the upper cervical spinal cord, creating an anatomical overlap — called the trigeminocervical complex — between head pain pathways and cervical sensory input. Misalignment at C1 or C2 can sensitize this structure, lowering the threshold at which head pain is triggered and amplifying pain signals that would otherwise remain subclinical.
Suboccipital muscle tension and referred pain. The suboccipital muscles — a group of small, deep muscles at the base of the skull — attach to the Atlas and Axis and are responsible for fine head movement and positional awareness. These muscles are among the most proprioceptor-dense tissues in the body. When the Atlas is misaligned, the suboccipital muscles are held in chronic contraction, producing sustained tension and referred pain patterns that travel into the scalp, temples, and forehead in patterns that closely mimic both tension and cervicogenic headache.
Greater occipital nerve compression. The greater occipital nerve exits between the Atlas and Axis and travels up the back of the skull. Upper cervical misalignment and associated muscle tension can compress or irritate this nerve, producing occipital neuralgia — a pattern of sharp, shooting, or electric pain in the back of the head and scalp that is often mistaken for migraine or severe tension headache.
Cerebrospinal fluid and intracranial pressure. The craniocervical junction plays a role in normal CSF circulation. Structural abnormalities in this region may contribute to intracranial pressure changes associated with certain headache patterns, particularly morning headaches and those associated with position changes.
Vertebral artery flow. The vertebral arteries pass through the transverse foramina of the upper cervical vertebrae on their way to the brainstem and cerebellum. Structural changes in the upper cervical spine can influence blood flow through this pathway, which may be relevant for headache patterns with a vascular component.
A Thorough Evaluation Before Any Adjustment
Every new headache patient at San Jose Chiropractic receives a comprehensive evaluation before any adjustment is made. Dr. O takes a detailed health history covering the onset, pattern, location, frequency, intensity, and triggers of your headaches, as well as any associated symptoms, prior treatments, and relevant medical history.
This is followed by a neurological and orthopedic assessment including balance testing, cranial nerve evaluation, cervical range of motion assessment, and postural analysis. When clinically indicated, Dr. O takes specialized upper cervical X-rays to determine the exact position of the Atlas and Axis relative to the skull and to each other.
The X-ray analysis allows Dr. O to calculate the precise correction needed for each patient's individual anatomy — not a generic adjustment, but a specific vector based on your imaging. She will walk you through what the findings show and give you an honest assessment of whether upper cervical misalignment appears to be a significant contributor to your headache pattern.
The Orthospinology Adjustment
Dr. O uses the Orthospinology technique, a precision-based form of upper cervical chiropractic care that delivers the correction via a specialized instrument rather than manual force. There is no twisting of the neck and no cracking. The amount of force involved is approximately what you would feel pressing lightly on the tip of your nose.
Post-adjustment X-rays confirm that the Atlas moved to the corrected position. You do not have to take Dr. O's word that the adjustment worked — the imaging confirms it objectively before you leave the office.
Adjustments Only When the Spine Needs It
One of the most important aspects of upper cervical care at San Jose Chiropractic is that Dr. O checks alignment at every visit but only adjusts when the spine has actually shifted out of position. The goal is to help the body hold the correction for progressively longer periods of time. As this stabilization develops, most patients experience a corresponding reduction in headache frequency and intensity. A visit where no adjustment is needed is a sign of progress.
What Headache Patients Typically Experience Over Time
As upper cervical alignment improves and the body begins to stabilize, headache patients at San Jose Chiropractic commonly report:
-
Fewer headache days per month
-
Reduced headache intensity when episodes do occur
-
Shorter headache duration
-
Less reliance on over-the-counter or prescription pain medication
-
Reduced neck and shoulder tension between headache episodes
-
Improved sleep quality and morning comfort
-
Better ability to work through the day without headache interference
The rate of improvement varies depending on how long the misalignment has been present, the headache type, and individual factors including overall health, lifestyle, and postural habits. Dr. O monitors your progress carefully and adjusts your care plan based on how your body is responding at each stage.
Post-traumatic headaches following a car accident are one of the most common presentations at San Jose Chiropractic. Even low-speed rear-end collisions can produce Atlas misalignment through whiplash-type forces — and the headaches that result can persist long after the soft tissue swelling and acute pain have resolved.
If your headaches began or significantly changed after a car accident in Jacksonville, upper cervical evaluation should be part of your recovery plan. You can learn more about how Dr. O approaches car accident injuries at San Jose Chiropractic.
Headache patients often present with other symptoms that are connected to the same upper cervical dysfunction.
Conditions that frequently accompany headaches and respond well to upper cervical care include:
-
Vertigo and dizziness
-
Neck pain and stiffness
-
TMJ and jaw pain
-
Sinus congestion and pressure
-
Ear infections and Eustachian tube dysfunction
-
Tinnitus and ear fullness
-
Neuropathies and nerve symptoms
