Car Accident Headaches & Brain Injuries
Headaches following a car accident are often dismissed as minor, but they can signal serious, even life-threatening, brain injuries.
A blow to the head in a crash can cause bruising, swelling, and soft tissue damage to the brain.
Victims can suffer headaches even if they didn't hit their head in the wreck.
The sudden and violent jolt of a motor vehicle accident can cause concussions or whiplash leading to intense headaches even if you didn't receive a blow to the head.
In severe cases headaches may indicate an intracranial hemorrhage or brain bleed.
Blood vessels damaged in a crash are weakened and can rupture from the force of a collision or in the days to follow as swelling sets in.
If you have a severe or persistent headache after a car accident you should NEVER ignore it.

Severe and consistent headaches after a crash may indicate a concussion or brain injury requiring immediate treatment.
Unrecognized and untreated, bleeding can cause further brain damage and prove fatal.
At Lawsuit Legal our auto accident attorneys regulary encounter collision victims with headaches that were the result of undiagnosed brain injuries. After a serious accident contact our personal injury lawyer now to get a free case consultation to get the help you need.
Types of Headaches Car Accidents Can Cause
Fracture Headaches
Symptoms of a skull fracture can include swelling, severe pain, and bleeding from the ears, nose, or eyes. The force of hitting your head against the vehicle's windshield or dashboard can result in a fractured skull and cause constant headaches. We most commonly encounter intracrannial bleeds caused by bone fragments penetrating the sensitive membrane surrounding the brain caused by the impact.
A severe blow to the head in a car accident can cause seizures in some cases.
Skull fractures are more easily diagnosed as a cause for chronic headaches after a car accident. A constant headache may indicate post-concussion syndrome. If left untreated, brain bleeds and swelling can lead to brain damage with severe consequences and the potential for chronic pain.
Sudden head pain at the base of the skull after a car accident should never be ignored, as ignoring the symptoms could risk life-long complications and even prove fatal.
Similarly, a feeling of pressure across the forehead, temples, or back of the head is a potential sign of an undiagnosed brain injury.

Muscle Strain Headaches
Whiplash headaches after a collision can even result without a direct blow to the head. When the soft tissues of the neck, head, and upper back muscles stretch and tear in a crash it can result in constant headaches. Tight muscles and spasms can cause inflammation and tension which presents as dull pain in the head along with pain performing certain movements. Spasm headaches caused by muscle damage can cause mobility issues and will typically appear within hours or days of an accident.
In the days following a collision the damage to muscle tissue is more likely to cause a post-traumatic headache as pain radiates up into the head from the injury site.
Whiplash Headaches
Can whiplash cause brain injury?
When involved in a collision the driver and passenger's heads experience unnatural, rapid and forceful movements known as whiplash. This intense movement can be side to side but is normally back to front. This can cause an acceleration deceleration injury to the brain.
How does whiplash cause brain damage if I didn't hit my head?
Our brain rests comfortably within our skulls encased in cerebral fluid. Suspended in this fluid our brain avoids hurting itself by not hitting the hard inner skull.
During whiplash the violent shaking of the brain within the skull causes the brain tissue to hit the inner skull. The damage can occur without contact in a sudden stop car accident. Cranial bruising and bleeding can result as well as the unbalancing of cerebral fluid. When this happens damage to the sensitive brain tissue and blood vessels can result in whiplash headaches or more severe damage.
The brain essentially bounces around inside the skull during the rapid acceleration-deceleration of whiplash, potentially leading to bruising, bleeding, and disruption of cerebrospinal fluid.
Brain injuries from whiplash-induced trauma are considered TBI and should be treated as such. The result of this injury will cause painful long term damage and debilitating headaches.
Concussion Headaches
Concussions are a mild form of traumatic brain injury with symptoms that commonly include headaches. While most people recover completely after a few weeks, if post-concussion symptoms persist it is important to review your condition with a neurologist. Other symptoms of a car accident concussions may include confusion and potential memory loss for the time surrounding the crash. Post-concussive headaches can range in severity and present complex symptoms unlike a normal headache depending on the nature of the injury.
While head pain is to be expected after suffering a concussion, chronic headaches may be indicative of something more serious and you should consult your doctor..
Debilitating Tension Headaches (Chronic Head Pain)
Persistent headaches after blow to the head should not be ignored. It may indicate a severe concussion or something more serious. Minor vehicle collisions can result in mild traumatic brain injury even without a direct impact to the head.
The first long-term effect of minor cranial trauma can be tension headaches. These can last from 30 minutes to an entire week. This head pain can happen all day or occasionally everyday. This condition is debilitating and may be chronic.
Post-accident headaches or migraines are chronic when occurring for more than 15 days a month for a minimum of three straight months. Chronic headaches are debilitatingly and change people’s lives forever.
Thunderclap Headache
A sudden onset "Thunderclap" headache is an indication of a burst blood vessel. It is described by sufferers as a severe headache, with excrutiating pain, that reaches maximum intensity after about 60 seconds. A thunderclap headache is extremely painful, comes on suddenly, and may indicate an artery is bleeding inside the skull in the space around your brain. It is considered a medical emergency and is often described by victims as "the worst headache ever."
In the case of a subarachnoid hemorrhage, if the bleeding is not stopped the pressure will build up in the skull and can prove fatal. It is important to seek medical attention right away to treat the aneurysm rupture and subsequent bleeding in such cases.

6 Signs of Brain Injury After a Car Accident
Car accident victims who sustain head injuries may experience no symptoms at first. The signs and severity of brain damage can start slowly, appearing hours or days later after a crash.
Persistent post-concussive symptoms can persist for months after the initial head injury and it is important to stay vigilant for the signs indicating something more serious.
Six Signs You May Have a Undiagnosed Brain Injury:
- Dull and aching headache or recurring migraines
- A general feeling of tightness/pressure across your forehead, around your temples or on the back of you head
- Tenderness around the scalp, any part of the neck or top of the shoulders
- Loss of appetite with nausea and dizziness
- You briefly lost consciousness during the accident
- Your mood, personality or cognitive ability seem different
Confusion, light sensitivity, vomiting, and memory loss after an accident are symptoms to be taken seriously and may indicate you have been concussed or worse. When symptoms of concussion persist for weeks or more you may have post-concussive syndrome. Concussion-related headaches can last for days, weeks, and even months after the initial impact.
Additionally, sudden onset severe headaches can indicate a hematoma requiring medical attention.
Car accident caused brain bleeds, if not treated quickly, can be life-threatening. Seek professional medical treatment after a motor vehicle accident to diagnose and treat the full extent of your injuries.
You may not experience these symptoms right away. If you suspect possible concussion after a traffic accident, a traumatic brain injury lawyer experienced with acquired tbi cases can help make sure you connect with the right medical experts for a proper diagnosis and the treatment you need.
Why are Auto Accident Brain Injuries Often Missed

Even minor motor vehicle accidents put tremendous strain on the body. Some delayed symptoms like intracranial hemorrhage can prove deadly. There are 4 main reasons why brain injuries can be hidden or missed.
Accident victims don’t feel immediate pain.
- During a crash your body releases massive amounts of adrenaline and cortisol. These hormones are designed to protect the body during traumatic events. This protection comes at price. The hormones can mask auto injury. These delayed injury symptoms may not be noticable for days or weeks after a car crash.
The Human Brain overcomes damage.
- The human brain is an extremely powerful and resilient organ. When damaged other parts of the brain will take over the tasks for the damaged area. This way loss of vital bodily function does not happen. Overtime however the damaged area or overworked area will begin to put strain on the brain.
Closed Head Injuries can’t be seen.
- Damage in to the brain may not result in a visible or palpable diagnosis. During a palpation examination of the head medical professionals may not find an issue. This is because the inner damage may not result in outer head swelling and brain scans are needed to properly diagnose.
Neck and Spinal Pain
- The brain is connected by the neck to the spine. The cerebrospinal fluid encases the brain and spine. When the brain is damaged this fluid pressure can result in neck and spine pain. Accident victims believe they only have a back injury when in actuality the brain is injured.
The reasons why interior brain damage can go unnoticed or misinterpreted are known to medical professionals. In rare cases doctors disregard these symptoms resulting in harmful patient outcomes, medical malpractice and liability.
In a majority of cases it is the car accident victims suffering brain injury who under report or live with the pain that develops over time. An example of a common undiagnosed brain injury is when someone does not even hit their head with an impact to the dashboard or windshield, but the sudden jerking motion of the vehicle crash causes damage.
Was your crash strong enough to bend metal?
A good rule of thumb used by experienced car accident attorneys is that if the crash was strong enough to bend metal, it was strong enough to potentially cause serious injury, warranting immediate medical attention.
