The overlooked connection between your neck, nervous system, and lingering post-concussion symptoms

Headaches after a concussion are incredibly common—and for many people, they don’t go away as quickly as expected. While some individuals recover within a few weeks, others continue to experience persistent headaches, brain fog, dizziness, and neck pain for months or even longer.

If you’re dealing with ongoing headaches after a concussion, it can feel frustrating and confusing. You may have been told everything looks “normal,” yet your symptoms remain. Understanding why these headaches persist is the first step toward finding real relief—and for many patients, the answer involves both the brain and the neck.

Many patients we see for headache and migraine treatment also have a history of concussion, even if the injury happened months or years ago.

What Happens to the Brain During a Concussion

A concussion is a form of mild traumatic brain injury that occurs when the brain experiences a sudden movement or impact. This can happen during sports injuries, car accidents, falls, or even minor bumps to the head.

During a concussion:

• The brain shifts rapidly inside the skull
• Nerve cells become temporarily disrupted
• Blood flow and energy use in the brain can change
• Communication between different parts of the brain may become less efficient

This disruption can lead to symptoms like:

• Headaches
• Dizziness or vertigo
• Brain fog or difficulty concentrating
• Sensitivity to light and sound
• Fatigue

Even though these changes are often not visible on imaging, they can significantly impact how you feel day to day.

Why Headaches Can Last for Months

One of the most frustrating aspects of a concussion is that symptoms don’t always resolve quickly. Many people develop persistent symptoms that last well beyond the initial injury.

There are several reasons headaches may continue:

1. Nervous System Imbalance

After a concussion, the nervous system can remain in a heightened or dysregulated state, making it more sensitive to stress, light, and movement.

2. Altered Blood Flow

Changes in circulation to and from the brain can contribute to ongoing pressure, headaches, and fatigue.

3. Increased Sensitivity

The brain may become more reactive after injury, meaning even minor triggers can provoke symptoms.

4. Unresolved Structural Issues

This is one of the most overlooked reasons headaches persist—especially when patients are told everything is “fine,” but they still don’t feel right.

Neck Injuries After Head Trauma

Many people think of a concussion as only a brain injury, but the neck is almost always involved.

The same force that causes a concussion often creates strain in the cervical spine, similar to whiplash. This can lead to:

• Muscle tension and inflammation
• Joint irritation
• Misalignment in the upper cervical spine

The upper cervical spine plays a critical role in protecting the brainstem and supporting proper nervous system function. When this area is not functioning correctly, it can contribute to:

• Headaches that start at the base of the skull
• Neck pain and stiffness
• Dizziness or vertigo
• Brain fog and fatigue

Many patients with persistent concussion symptoms also benefit from addressing underlying neck pain and spinal dysfunction.

In fact, headaches that originate from the neck are often referred to as cervicogenic headaches—and they are commonly missed.

Natural Approaches to Recovery

If you’re dealing with ongoing headaches after a concussion, a comprehensive and gentle approach to recovery is essential.

1. Address the Neck and Upper Cervical Spine

Evaluating the alignment and function of the upper neck is often a key step. Gentle, precise care can help reduce irritation in the nervous system and support healing.

2. Support the Nervous System

Reducing overstimulation, managing stress, and allowing time for recovery can help regulate the nervous system.

3. Gradual Return to Activity

A guided return to normal movement and activity helps the brain and body adapt without overwhelming the system.

4. Improve Sleep Quality

Better sleep supports brain repair and can reduce headache frequency and intensity.

5. Take a Whole-Body Approach

Persistent symptoms often involve multiple systems. Addressing structural, neurological, and lifestyle factors together can improve outcomes.

When to Seek Help

If headaches continue weeks or months after a concussion, it may be time to look deeper.

You may benefit from an evaluation if you experience:

• Persistent headaches
• Neck pain or stiffness
• Dizziness or balance problems
• Brain fog or difficulty concentrating
• Symptoms that worsen with activity

You don’t have to wait indefinitely for symptoms to resolve. Many patients begin to improve once the underlying cause is identified and addressed.

Final Thoughts

Headaches after a concussion are common—but they are not something you have to simply live with. When symptoms persist, it’s often because an underlying issue has not yet been addressed.

For many patients, especially those with dizziness, brain fog, and neck tension, the missing piece is the connection between the neck and the nervous system.

By taking a more comprehensive approach—and addressing both neurological and structural factors—it’s possible to reduce symptoms, improve function, and move toward long-term recovery.

If you’re still struggling with symptoms after a concussion, exploring a more targeted approach to headache, neck pain, and dizziness care may be an important next step.
