Headache and Dizziness After a Car Accident? Here's How Radius Helps You Heal
If you’ve recently been in a car accident and are now experiencing headaches, dizziness, or brain fog—you’re not alone. These symptoms are incredibly common after motor vehicle collisions and can make it difficult to return to normal life. At Radius Physical + Sports Rehab, we focus on helping people recover from auto injuries with compassionate, evidence-based care.
Whether you’re dealing with whiplash, concussion, or soft tissue injury, our team is trained to identify the root cause of your symptoms and guide you through a safe, personalized recovery plan.
Why You Might Feel Dizzy or Headachy After a Car Accident
Auto collisions involve intense forces, and even low-speed crashes can cause damage to the head, neck, and nervous system. According to the National Highway Traffic Safety Administration (NHTSA), up to 50% of people hospitalized after a crash experience ongoing headaches or dizziness.
These symptoms may signal an underlying issue such as:
- Concussion or traumatic brain injury (TBI)
- Whiplash-associated disorders
- Vestibular dysfunction (inner ear)
- Cervicogenic dizziness (neck-related balance problems)
- Vascular issues affecting blood flow to the brain
- Muscle tension and hypertonicity in the neck and upper back
Many of these conditions can go undiagnosed without a skilled evaluation. That’s why it’s essential to seek care from providers experienced in post-accident musculoskeletal and neurological assessments—like our team at Radius.
Common Auto Injury-Related Headache Conditions We Treat:
A concussion occurs when the brain moves rapidly inside the skull during impact. Symptoms include headaches, sensitivity to light, memory problems, and difficulty concentrating. Even mild concussions can lead to long-term effects if not properly addressed.
The sudden back-and-forth movement of the head during a crash strains muscles, ligaments, and nerves in the neck. Whiplash often presents with lingering headaches, neck pain, and dizziness.
Tight or hypertonic muscles in the upper back, shoulders, and neck can compress nerves and cause tension-type headaches. We identify and treat these muscle imbalances through soft tissue therapy and targeted rehab.
More serious than a concussion, a cerebral contusion involves bleeding in the brain and may require urgent medical care. Radius collaborates with local medical teams to co-manage more complex injuries.
Dizziness & Balance Issues After a Crash
Whatever it is, the way you tell your story online can make all the difference.
Feeling dizzy or off-balance? That could be due to one of several post-trauma vestibular or neurologic issues, including:
Auto collisions can dislodge calcium crystals in the inner ear, leading to vertigo and balance problems. Radius providers are trained in vestibular repositioning maneuvers to help reset this system.
Neck trauma can interfere with the body’s ability to coordinate head movement and balance—resulting in dizziness and visual tracking problems. We treat this through a combination of manual therapy, nerve retraining, and movement restoration.
In more severe crashes, the vessels that supply blood to the brain can be disrupted. Symptoms include dizziness, pressure headaches, or faintness. We always screen for red flags and coordinate imaging or specialist referrals when needed.

Frequently Asked Questions
Common questions about headaches and dizziness after a car accident.
Why do headaches and dizziness happen after a car accident?
Headache is the most common physical complaint after a traumatic brain injury, with a reported prevalence ranging from 30% to 90%. Dizziness and vertigo are also very frequently present among the symptoms of cervical whiplash injuries. After a crash these symptoms can arise from several mechanisms, including neck (cervical) structures, disrupted vestibular (inner-ear) or balance systems, and concussion, and more than one mechanism can be involved at the same time.
What is a cervicogenic headache after whiplash?
A cervicogenic headache is pain that starts in the neck and is referred to the head, arising from bony or soft-tissue structures innervated by the upper cervical spinal nerves (C1–C3). It usually accompanies reduced neck range of motion. About 70% of cases involve the C2–3 facet (zygapophyseal) joint, and whiplash from a motor vehicle accident can cause arthritis of that joint, which is one reason these headaches follow neck trauma.
Why do people feel dizzy or off-balance after whiplash?
Vertigo and postural instability are very frequently present among the symptoms of cervical whiplash injuries, and dizziness is referred even more frequently by people who also had a minor head injury. Post-whiplash dizziness may come from vestibular (inner-ear) damage or from altered proprioceptive input from the neck affecting the vestibulospinal reflex, which helps control balance. Both mechanisms can occur.
What is cervicogenic dizziness?
Cervicogenic dizziness is a non-rotatory dizziness associated with neck pain and/or reduced neck mobility, thought to result from altered proprioceptive (position-sense) input from the cervical spine. It is a diagnosis of exclusion: other causes of dizziness, including central nervous system, cardiovascular, and peripheral vestibular (inner-ear) disorders, need to be ruled out first, because specific confirmatory tests for cervicogenic dizziness do not currently exist.
What are the symptoms of post-concussion syndrome after a crash?
Postconcussive syndrome is a constellation of physical, cognitive, behavioral, and emotional symptoms occurring after a traumatic brain injury. Reported symptoms include headache, fatigue, vision changes, disturbances in balance, confusion, dizziness, insomnia, and difficulty concentrating, along with irritability and sleep and mood disturbance. Dizziness and balance problems are among the top complaints after a concussion and have the greatest ability to predict a longer recovery.
How long do headaches and dizziness last after a concussion?
Approximately 90% of concussion symptoms are transient and typically resolve within 10 to 14 days. When symptoms persist beyond 3 months, this is called persistent postconcussive syndrome; a minority of patients (about 10% to 15%) have symptoms lasting more than one year. Persistent post-traumatic headache is likewise defined as headache that has not resolved within 3 months of the injury. Recovery timelines vary from person to person.
When should I seek medical care for headaches or dizziness after a car accident?
Seek medical help immediately after any head injury. For headache after trauma, any acute change in neurologic status, or a sudden change in the frequency and intensity of the headache, may warrant urgent evaluation and imaging, because posttraumatic headache can occasionally signal serious problems such as bleeding, stroke, or cervical artery dissection. Increasing or worsening symptoms after a crash are a reason to be evaluated rather than to wait.
How are post-accident headaches and dizziness treated?
Treatment depends on the cause and is generally conservative. For cervicogenic headache, physical therapy is considered the first-line treatment. For cervicogenic dizziness, there is level 2 evidence supporting cervical manual therapy, sometimes combined with neck-specific exercises. After concussion, care may include a short period of rest followed by early, symptom-guided, paced exercise and, when dizziness or balance is involved, vestibular physical therapy. Treatment is tailored to the individual.

It is not medical advice or a diagnosis, and it cannot tell you what is causing your symptoms. Reading it is not a substitute for an in-person evaluation, and booking a visit does not confirm that your condition is right for our care until a provider has examined you. This information cannot identify every condition, and some urgent problems can feel like musculoskeletal pain. If your symptoms are severe or getting worse, or you are unsure how urgent they are, contact your physician, call 911, or go to the nearest emergency room. When in doubt, seek emergency care.
