A headache after a car accident can be easy to dismiss. You may assume that you're stressed, didn't sleep well, or simply need some time to recover from the shock of the collision. But when headaches begin following a motor vehicle accident, particularly when they occur along with neck pain or stiffness, the neck may be one of several possible sources that should be considered.

During a collision, the head and neck can be subjected to rapid acceleration, deceleration and changes in direction. These forces may affect the muscles, ligaments, joints and other structures of the cervical spine. In some patients, headaches can develop along with these neck-related symptoms.

At Texas Spine and Joint Rehabilitation in Mesquite, Texas, Dr. Daniel L. Pennell, D.C. evaluates patients suffering from musculoskeletal injuries following motor vehicle accidents. When a patient reports a headache after a car accident, an important part of the evaluation is determining what symptoms are present, whether the neck may be contributing, and whether the patient needs additional medical evaluation.

There isn't one single explanation for every headache following a collision.

A motor vehicle accident can place considerable stress on the head, neck and upper body. Even when the head does not directly strike an object, sudden movement of the cervical spine may injure or irritate structures within the neck.

Potential causes or contributors to headaches following a collision can include:

• Whiplash-associated neck injury
• Cervical muscle and ligament injuries
• Irritation of joints within the cervical spine
• Muscle tension or spasm
• Head injury or concussion
• Other neurological or medical causes

This distinction is important because a headache related to neck dysfunction is not evaluated or managed in exactly the same way as a headache caused by a concussion or another medical condition.

The cervical spine contains joints, muscles, ligaments and nerves that work together to support and move the head.

Following a car accident neck injury, some of these structures can become painful or irritated. Pain originating from structures in the neck can sometimes be perceived in areas of the head. This is commonly referred to as a cervicogenic headache.

A person may experience discomfort beginning around the neck or base of the skull and extending toward other areas of the head. Neck stiffness or reduced range of motion may occur at the same time.

This is one reason that evaluating only the location of the headache may not tell the entire story.

When a headache begins after an accident and is accompanied by neck pain after a car accident, evaluating the cervical spine can be an important part of determining what may be contributing to the symptoms.

Whiplash is one of the most commonly recognized neck injuries associated with automobile collisions, particularly rear-end accidents.

During a rear-end collision, the head and neck can move rapidly in relation to the torso. This sudden motion can stress the soft tissues and joints of the cervical spine.

Although neck pain and stiffness are commonly associated with whiplash, patients may experience other symptoms as well.

These can include headaches, shoulder or upper-back discomfort, reduced neck movement, muscle tightness and, in some cases, symptoms extending into an arm.

Importantly, the severity and combination of symptoms can vary considerably from one person to another.

Not every car accident headache begins at the scene of the collision.

Some people feel relatively normal immediately afterward and develop headaches, neck stiffness or soreness several hours later or the following day.

There are several reasons symptoms can become more noticeable with time. The body's stress response surrounding the collision may temporarily affect pain perception, while inflammation, muscle guarding and soft-tissue irritation may evolve after the initial injury.

Therefore, the absence of an immediate headache does not necessarily establish that later symptoms are unrelated to the collision.

The timing of the symptoms, associated complaints and examination findings all need to be considered.

This is particularly important.

Not every headache following a collision originates from the neck. Motor vehicle accidents can also cause head injuries, concussion and, less commonly, serious intracranial injuries.

Emergency medical evaluation should be considered for concerning symptoms such as:

• A severe or rapidly worsening headache
• Loss of consciousness
• Repeated vomiting
• Significant confusion or unusual behavior
• New weakness or numbness
• Difficulty speaking or walking
• Seizure
• Significant vision changes
• Increasing drowsiness or difficulty waking

A chiropractic or rehabilitation evaluation is not a substitute for emergency care when signs of a potentially serious head injury or neurological emergency are present.

When there is uncertainty about the seriousness of symptoms following significant trauma, seeking prompt medical evaluation is appropriate.

When headache occurs alongside neck pain, stiffness or restricted movement, the cervical spine deserves careful evaluation.

For example, a patient may report that turning the head while driving has become difficult. Another may experience pain around the base of the skull along with significant tightness through the neck and shoulders.

The important question isn't simply:

“How do we stop the headache?”

It is also:

“Why did the headache begin after the accident?”

Determining whether the cervical spine may be contributing allows treatment to address the underlying musculoskeletal findings rather than focusing solely on temporarily reducing symptoms.

At Texas Spine and Joint Rehabilitation, evaluation begins with understanding what happened during the accident and what symptoms developed afterward.

The examination may include assessment of:

• Cervical range of motion
• Areas of pain and tenderness
• Muscle tightness or spasm
• Orthopedic findings
• Neurological findings
• Spinal and joint function
• Upper-extremity symptoms
• Functional limitations

The patient's medical history, mechanism of injury and progression of symptoms are also important.

When examination findings or symptoms indicate that further investigation is necessary, Dr. Daniel L. Pennell, D.C. may recommend additional imaging or referral to an appropriate medical provider.

Not necessarily.

An MRI is not automatically required simply because someone develops a headache or neck pain after a collision.

Imaging decisions should be based on the patient's history, symptoms, physical examination, neurological findings and clinical progress.

X-rays can provide useful information about certain aspects of the spine but do not directly visualize structures such as spinal discs in the same manner as MRI.

If symptoms persist, neurological findings develop, or examination findings suggest that additional information is needed, advanced imaging may sometimes become appropriate.

The important point is that diagnostic imaging should be clinically driven, rather than automatically ordered for every accident patient.

When an examination indicates that a patient's headache may have a musculoskeletal component related to the cervical spine, treatment can be directed toward the identified injury.

Depending on the patient's condition, car accident rehabilitation may incorporate chiropractic treatment, therapeutic exercises and other supportive rehabilitation procedures.

The goals may include improving cervical mobility, reducing muscle guarding, restoring normal movement and helping the patient return to normal activities.

Every accident injury is different, which is why treatment should be based on the individual patient's findings rather than a predetermined treatment schedule.

A headache following an accident shouldn't automatically be assumed to be serious—but it shouldn't automatically be dismissed either.

The first priority is determining whether symptoms suggest a head injury or another condition requiring urgent medical evaluation.

When serious causes have been appropriately considered and the patient is also experiencing neck pain, stiffness or restricted movement, the cervical spine may be an important part of the clinical picture.

An appropriate evaluation can help determine whether a neck injury after a car accident may be contributing to the headache and what treatment or additional evaluation may be appropriate.

Is it normal to have a headache after a car accident?

Headaches can occur following motor vehicle accidents for several reasons, including neck injuries such as whiplash, muscle tension, concussion or other conditions. Because the cause can vary, new or persistent headaches following an accident should be evaluated based on the patient's individual symptoms and circumstances.

Can whiplash cause headaches?

Headaches can occur in association with whiplash and other cervical spine injuries. Some patients experience pain around the neck or base of the skull along with stiffness and reduced cervical movement.

Can my neck cause headaches after a car accident?

It can. Certain headaches can originate from or be associated with structures in the cervical spine. When headache occurs together with neck pain, stiffness or restricted movement following a collision, evaluation of the neck may be appropriate.

How long after a car accident can a headache start?

Some headaches occur immediately, while others become noticeable hours or sometimes days after a collision. The timing alone does not determine the cause, so persistent, worsening or concerning symptoms should be properly evaluated.

When should I go to the ER for a headache after a car accident?

Emergency evaluation may be appropriate for a severe or rapidly worsening headache, loss of consciousness, repeated vomiting, confusion, seizure, new weakness or numbness, speech or walking difficulties, significant vision changes or increasing drowsiness.
