A car accident can happen in seconds, but the pain it causes could stay with you for months or even years. If your back is still hurting weeks after a collision and isn’t improving, you may be dealing with chronic back pain after a car accident, that can be more common than many realize.
Back pain is one of the most frequently reported injuries following a motor vehicle accident (MVA) in Canada. While many people expect to feel better within a few days or weeks, a significant number find that their pain lingers well beyond that window.
When back pain persists for 12 weeks or longer, it is classified as chronic, and it requires a different, more structured approach to care than acute pain management.
Understanding why back pain becomes chronic after a collision is the first step toward finding real, lasting relief.
Don’t let chronic back pain get in the way of daily activities.

Is Chronic Back Pain After a Car Accident Common?
Back pain is far more common than many drivers and passengers expect. Research shows that a large proportion of people involved in motor vehicle accidents experience persistent pain, with the back and neck being the most frequently affected areas.
According to the Public Health Agency of Canada, back pain is already one of the
leading causes of disability in the country, and car accidents are a
significant contributor to new cases of chronic back and spinal pain each year. (1)
In Ontario, the Financial Services Regulatory Authority (FSRA) recognizes back injuries as among the most common claims following motor vehicle accidents, and whether you were rear-ended at a traffic light, involved in a side-impact collision, or experienced a rollover, the forces involved in even a low-speed crash can cause injury to the spinal structures, muscles, and connective tissues of your back.
What Causes Chronic Back Pain After a Car Accident?
The forces involved in a motor vehicle accident place enormous and sudden stress on your spine and surrounding tissues, and even when there is no visible external injury, significant internal damage can occur.
Here are the most common causes of chronic back pain following a collision:
1. Whiplash-Associated Disorders (WAD)
Most people associate whiplash with neck pain, but the rapid back-and-forth motion of a rear-end collision also affects the thoracic and lumbar spine. Whiplash-associated disorders can cause muscle tears, ligament sprains, and joint inflammation throughout the entire spinal column, contributing to both upper and lower back pain after a motor vehicle accident.
2. Herniated or Bulging Discs
The sudden compression and shearing forces of a car crash can cause the soft discs between your vertebrae to bulge or rupture. A herniated disc after a car accident can press on nearby spinal nerves, causing chronic pain, radiating discomfort down the leg (sciatica), numbness, or tingling.
This type of injury often does not show up on initial assessments and may worsen in the weeks following the collision if left untreated.
3. Facet Joint Injuries
The facet joints, small joints that link each vertebra, are highly vulnerable to the sudden, forceful movement of an MVA, and facet joint syndrome following a car accident is a well-documented cause of persistent lower and mid-back pain.
The pain is often described as deep, aching, and worse with rotation or extension of the spine.
4. Sacroiliac (SI) Joint Dysfunction
The SI joint, which connects the spine to the pelvis, can be sprained or destabilized during a collision, particularly in side-impact crashes or if you braced hard against the floorboard at the moment of impact.
SI joint dysfunction causes pain in the lower back and upper thighs that can easily be mistaken for disc-related pain.
5. Muscle and Soft Tissue Injuries
Sprains and strains of the muscles and ligaments supporting the spine are extremely common in car accidents. While many soft tissue injuries resolve within weeks, more significant tears or injuries to deep stabilizing muscles can result in chronic soft tissue back pain that persists for months without targeted rehabilitation.
6. Spinal Fractures (Compression Fractures)
In higher-speed collisions, the vertebrae themselves can sustain compression fractures. These are not always immediately obvious and can contribute to ongoing pain and instability. This is one reason why imaging and evaluation after any significant collision is essential.
7. Central Sensitization
When pain persists after a car accident, the nervous system itself can become sensitized, meaning it begins to amplify pain signals even after the original tissue injury has healed. This process, known as central sensitization, is often why post-accident back pain could become chronic in some people.
Red Flags for Back Pain After a Car Accident: When to Seek Urgent Care
After any motor vehicle accident, some back pain symptoms are more serious than others. While soreness and stiffness are expected, certain warning signs indicate a potentially serious spinal injury requiring immediate medical attention.
Go to the emergency room or call 911 if you experience:
- Bladder or bowel dysfunction after the accident (inability to urinate or loss of control)
- Numbness or tingling
- Progressive weakness in your legs or difficulty walking
- Severe, constant pain that is worsening and not relieved by any position
- Visible deformity of the spine or inability to bear weight
- Loss of consciousness during or after the collision
- Neck or back pain following a crash, rollover, or collision
See a physician or registered health professional promptly if:
- Your back pain is not improving after 1–2 weeks of rest
- Pain is radiating down your leg
- You experience persistent headaches alongside your back pain
- You notice increasing stiffness or reduced range of motion over time
In Ontario, you are entitled to access treatment for motor vehicle accident injuries through your auto insurance policy’s Statutory Accident Benefits Schedule (SABS), regardless of who was at fault for the accident.
How to Manage Chronic Back Pain After a Car Accident
Recovering from a post-accident back injury, especially when pain has become chronic, responds to multi-modal treatments.
Physiotherapy After a Car Accident
Physiotherapy is one of the most well-supported treatments for chronic back pain following a motor vehicle accident. Our registered physiotherapists will assess your injury, identify impaired movement patterns and muscle imbalances, and develop a rehabilitation plan that may include manual therapy, therapeutic exercises, cold laser therapy, ultrasound or shockwave therapy.
In Ontario, physiotherapy is directly billable to most auto insurance providers under SABS.
Chiropractic Care After an MVA
Chiropractic treatment is widely used in post-MVA rehabilitation across Canada. Spinal manipulation and joint mobilization can help restore movement, reduce pain from facet joint and soft tissue injuries, and improve spinal alignment disrupted by the forces of a collision. At Core Wellness Centre, spinal decompression therapy and Y Strap adjustments are available alongside chiropractic adjustments and the activator method.
Like physiotherapy, chiropractic care is typically covered under Ontario’s accident benefits.
Registered Massage Therapy (RMT)
RMT massage therapy after a car accident addresses the chronic muscle tension, guarding patterns, and soft tissue restrictions that develop in the weeks and months following a collision.
RMTs work to reduce pain, restore tissue mobility, and support the nervous system in down-regulating the heightened pain response common in post-accident recovery.

FAQ - Frequently Asked Questions for Chronic Back Pain
How long does back pain last after a car accident?
Back pain after a car accident can range from a few days to several months, depending on the type and severity of the injury. Mild muscle strains often improve within 2–6 weeks with appropriate care.
However, when pain persists beyond 12 weeks, it is considered chronic, and this is more common than most people expect after a motor vehicle accident.
Injuries such as herniated discs, facet joint damage, and soft tissue tears may take considerably longer to heal, especially without proper rehabilitation. The earlier you begin treatment, the better your chances of a full and faster recovery.
Is back pain after a car accident covered by insurance in Ontario?
Yes. In Ontario, treatment for back pain and other injuries sustained in a motor vehicle accident is covered under the Statutory Accident Benefits Schedule (SABS), regardless of who was at fault for the collision.
This means you can access physiotherapy, chiropractic care, and registered massage therapy through your auto insurance benefits without paying out of pocket.
At Core Wellness Centre, we work directly with auto insurers and can help guide you through the claims process so you can focus on your recovery rather than the paperwork.
Can a minor car accident cause chronic back pain?
Yes, and this surprises many people. Even low-speed collisions, such as being rear-ended at under 30 km/h, can generate enough force to injure the spinal discs, facet joints, and soft tissues of the back.
The forces involved in a crash are transmitted through the vehicle and into your body very quickly, often before you have time to brace. In fact, being caught off-guard in a collision can result in more significant soft tissue injury than a higher-speed impact where the muscles are tensed.
If you are experiencing persistent back pain after what seemed like a minor accident, it is worth getting a proper assessment, the injury may be more significant than the crash appeared.
What treatments are available for chronic back pain
Effective treatments for chronic back pain following a motor vehicle accident are physiotherapy, chiropractic care, and RMT massage.
Physiotherapy addresses movement, strength, and function; chiropractic care targets spinal alignment and joint mobility; and RMT massage therapy works on muscle tension, soft tissue restriction, and nervous system regulation.
