Neck pain is one of the most common symptoms reported after a concussion, affecting nearly half of all concussion patients. In a study of 306 people diagnosed with concussions, 47% reported neck pain and about 22% had difficulty moving their neck. This makes sense when you consider that the same force that shakes your brain almost always passes through your neck first.
Why Concussions and Neck Pain Happen Together
A concussion is caused by a sudden acceleration-deceleration force to the head. That force can come from a direct blow to the head, face, or neck, or from an impact elsewhere on the body that transmits energy upward. The critical detail is that the neck absorbs this same force. The whiplash mechanism that strains the cervical spine is, biomechanically, identical to the “impulsive forces” described in concussion injuries.
Think of it this way: your brain doesn’t get rattled inside your skull without your neck being yanked in the process. The upper cervical spine is the most mobile segment of the entire spine, which makes it especially vulnerable during rapid back-and-forth movement. During that whiplash motion, muscles, ligaments, nerves, discs, and the small joints between your vertebrae can all be stressed to their limits. So a single impact often produces two injuries at once: one in the brain and one in the neck.
Overlapping Symptoms Make Diagnosis Tricky
Here’s what complicates things: the cervical spine is anatomically connected to structures that produce many of the same symptoms as a brain injury. Headache, dizziness, visual disturbances, ringing in the ears, and trouble concentrating can all originate from damaged neck structures rather than the brain itself. The small joints in the neck (called facet joints) are a known source of not just neck pain but also headaches, dizziness, and tinnitus when irritated after trauma.
This overlap means that some of what feels like a lingering concussion may actually be a neck problem, or it may be both happening simultaneously. Clinicians use several physical tests to tease apart the source. One involves checking whether you can accurately return your head to a neutral position with your eyes closed, which tests the position sensors in your neck muscles. Another has you track a moving target while your body is rotated, which can provoke symptoms specifically linked to neck dysfunction. These assessments help determine whether the brain, the neck, or both are driving your symptoms.
Neck Pain in Sports vs. Non-Sports Concussions
The likelihood of neck involvement depends partly on how the concussion happened. Among athletes, about 44% report neck symptoms after a concussion. In non-sports concussions (car accidents, falls, workplace injuries), that number jumps to 60%. This difference likely reflects the types of forces involved. A car crash or a hard fall tends to generate more violent whiplash than a collision on a playing field, putting greater strain on cervical structures.
What Current Guidelines Recommend
The 6th International Conference on Concussion in Sport, held in Amsterdam in 2022, now formally includes cervical spine evaluation as part of the standard concussion assessment. This means checking range of motion, feeling for muscle spasm, and pressing along the spine to identify tender spots. It’s a recognition that you can’t properly evaluate or treat a concussion without also looking at the neck.
If dizziness, neck pain, or headaches persist beyond 10 days after a concussion, the current consensus recommends a combined neck and vestibular rehabilitation program. This type of therapy targets both the balance system and the cervical spine together, because the two systems are deeply interconnected. Treating just the brain while ignoring a neck injury can leave symptoms lingering for weeks or months longer than necessary.
How Neck Rehabilitation Helps Recovery
Gentle neck exercises are now a standard part of concussion aftercare. These are not intense workouts. They typically take about 10 minutes a day and focus on restoring normal movement, rebuilding the fine muscle control around the cervical spine, and reducing the postural strain and muscle pain that develop after injury. When you hurt your neck, you naturally guard it by holding your head stiffly, which creates secondary tension and pain that feeds the cycle.
The goal is to break that cycle early. Restoring normal neck mobility can reduce headache frequency, improve balance, and resolve dizziness in cases where the cervical spine is a contributing factor. For some people, neck-focused therapy resolves symptoms that were mistakenly attributed entirely to the brain injury.
Warning Signs That Need Immediate Attention
Not all neck pain after a head impact is routine. Certain symptoms suggest a more serious spinal injury rather than simple soft tissue strain. Seek emergency care if you experience numbness, tingling, or weakness in your arms or legs after a head or neck impact. Inability to move your neck at all, severe pain at the midline of your spine, or pain that radiates down both arms warrants urgent evaluation. These can indicate damage to the spinal cord or vertebrae themselves, which requires imaging and possibly immobilization.
For neck pain without those red flags, the presence of stiffness and soreness after a head impact is expected and common. It does not necessarily mean your concussion is more severe. But it does mean the neck should be part of your recovery plan, not an afterthought.
