How a Chiropractor Can Treat the Most Common Car Accident Injuries

How a Chiropractor Can Treat the Most Common Car Accident Injuries

When John* pulled out from the Applebee’s on Pines Boulevard and stopped at the intersection on N. Palm Avenue, he had no idea his life was about to change for the worse.

He’d barely stopped at the light when another car hit him from behind. The collision occurred so fast that afterward, he could hardly remember how it happened.

It wasn’t a particularly nasty accident – his car only received a small dent. But it ruined John’s day. Unfortunately, he had no idea how long he would be feeling the effects of this wreck.

John initially didn’t believe he’d been hurt; he didn’t even go to the hospital following the accident. But three weeks later, he awoke with a throbbing headache and a stiff neck. He tried to treat the pain with over-the-counter medicines, but his symptoms worsened.

After a few weeks, he visited his doctor. John’s doctor put him on a prescription pain medication, which helped at first. But John’s symptoms grew worse and worse, and he needed a higher dosage every few days to dull the ache. John knew the cycle couldn’t continue, and so, on the advice of a friend, he made an appointment to see a Pembroke Pine’s chiropractor at Rush Chiropractic.

Like many other patients before him, John did not realize his symptoms were connected to the car accident he’d been in weeks earlier. It seemed so minor that he didn’t connect the dots. By now, the wreck was old news – insurance had been sorted, and if not for the pain, he would have forgotten the whole incident.

But even small rear-end collisions can have substantial physical effects.

The Physics of a Rear-End Collision

The Physics of a Rear-End Collision

Rear-end collisions are among the most common kinds of car accidents, and they account for about 50% of all two-vehicle accidents. The Washington Post reported in 2015 that about 1.7 million rear-end collisions happen each year.

According to the Insurance Information Institute, in 2019, 2,346 fatal crashes involved a rear-end collision, making up about 7% of all fatal crashes that year. And that doesn’t include all of the non-fatal crashes that resulted in injuries.

While injuries from a rear-end collision can range from the catastrophic to the superficial, even minor conditions can have dangerous long-term impacts. This is especially the case when injuries are left untreated, because like John, many people don’t even realize the effects a collision has had on their body until weeks or even years later.

even a minor wreck at slow speeds can cause severe damage

The injuries experienced during a rear-end collision will vary depending on how fast the two cars were going. But even a minor wreck at slow speeds can cause severe damage.

When another vehicle hits yours from behind, its momentum shifts to your car — and your body. If one car is sitting still — such as when waiting at a spotlight — or it’s going slower than the car that collided with it, that sudden motion can be traumatic.

A car going 20 miles per hour may not seem like it’s moving quickly, but imagine transferring that 20 miles per hour of momentum onto a human body very suddenly. This is essentially what happens in a collision.

Upon impact, both you and your car are jerked forward suddenly. If you are wearing a seatbelt, your body is snapped back just as quickly, causing your spine and head to crash against the seat behind you. Because you weren’t expecting the impact, you can’t brace against it. Your head snaps forward and backward in a violent motion. This can cause a cascade of injuries all up and down the spine.

And just like your head and spine are jerked forward and backward, imagine how a similar force could impact your internal organs. When your organs rapidly move forward and then backward in their cavities, they slam into rigid structures inside your body, like the ribcage. In the most severe cases, organs can rupture or tear.

How Seatbelts and Airbags Both Help and Hurt

How Seatbelts and Airbags Both Help and Hurt

Seatbelts and airbags are both important safety features that save many lives, but unfortunately, they also are not without risk.

In a rear-end collision, especially one at higher speeds, a seatbelt could be the sole factor that keeps you from being thrown from your car. In fact, the Center for Disease Control reports that seat belts reduce serious injuries and deaths from car crashes by about 50%.

The problem with seatbelts is that the force they exert to keep you from flying out of your seat can also cause your head and spine to snap back more forcefully after your vehicle is hit from behind. This can often cause whiplash and other spinal injuries.

Similarly, airbags deploy with tremendous force, so they can cause injuries such as broken bones, facial damage, concussions, and abdominal injuries. However, the National Highway Traffic Safety Administration reports that frontal airbags save thousands of lives each year. When airbags are deployed, they protect the driver and front seat passenger from hitting their heads or upper bodies on the dashboard or steering wheel, which could cause traumatic brain injury or even death.

In spite of the risks attached to them, the benefits of airbags and seatbelts far outweigh the costs. Any injury you may suffer from a seatbelt or airbag is likely less severe than the ones you would experience without protection.

Keep in mind that wearing your seatbelt properly and sitting straight in your seat with your feet on the floor — even when riding as a passenger — can help protect you from seatbelt and airbag injuries in the event of a collision.

How Can a Chiropractor Help After a Rear-End Collision?

Like John, your first instinct may be to visit a general practitioner when dealing with pain after a car accident. But in many cases, GPs will just prescribe pharmaceuticals that only mask your symptoms.

Since pain medication can’t address the root cause of your discomfort, it simply acts as a Band-Aid on the problem. And if your injury lingers like John’s did, you will need ever-increasing doses to manage your daily pain over time.

Fortunately, there is a second, better option. Chiropractic care treats and heals ailments without the use of drugs. And at Rush Chiropractic, we have a wide variety of treatments at our disposal, so we can work with you to diagnose the problem and develop a treatment plan that’s tailored to your needs.

Common Signs You Should See a Chiropractor

Common Signs You Should See a Chiropractor

If you think you have been injured in a rear-end collision, it’s important to seek out treatment immediately.

Many injuries can last for years if left untreated, and you never want to look back and realize you’ve been suffering for too long from something that could have been fixed with just a few chiropractic visits.

Additionally, back and neck injuries like whiplash or herniated discs can get more serious if left untreated, or they can have serious long-term effects throughout your body, as your posture or movement might change in a way that’s harmful to your hips, knees, or other joints.

This is why it’s so beneficial to work with a chiropractor. We don’t just help you find pain relief, but our treatment methods can also speed up your recovery time and strengthen the affected areas to reduce your risk of future injury.

With that in mind, here are some of the most common ailments people experience after a rear-end collision and an overview of some of the ways your chiropractor can treat them:

The Most Common Injuries in a Rear-End Collision

The Most Common Injuries in a Rear-End Collision


Whiplash is also known as a flexion/extension cervical injury, because it’s caused by a sudden extension (backward motion) of the head and neck, followed by a flexion (forward motion). This violent, uncontrolled motion can cause tearing in the ligaments, tendons, or other neck muscles.

Whiplash is an extremely common injury after rear-end collisions, because it can occur even in the most seemingly minor accidents. A study in the European Spine Journal found that whiplash can happen even at speed changes of less than 10 mph — such as when you’re sitting at a stoplight and a car bumps into you while moving at a slow velocity.

This condition can be difficult to diagnose without an X-Ray. That is partly because symptoms don’t always present themselves immediately after the incident, like with John’s pain that didn’t start until 3 weeks after his accident.

Plus, the most common whiplash symptoms are very similar to other spinal injuries. This makes it even more important to see an expert right away if you think you have whiplash, because you need to make sure you’re not suffering from a more serious condition like a.

Whiplash symptoms

Whiplash is most commonly associated with neck pain and stiffness, but it can also include symptoms like dizziness, fatigue, headaches, and a limited range of motion in your neck and shoulders.

In more severe cases, whiplash can also cause emotional issues, memory or concentration difficulties, and numbness in your arms and shoulders. If you experience any of these symptoms, make sure to visit a medical professional as quickly as possible.

Chiropractors typically take a gentle approach to whiplash. They may start with a combination of cold and heat therapies to reduce soreness and swelling in the muscles. Then they will proceed with careful spinal manipulation to restore the cervical spine’s proper alignment.

Additionally, at Rush Chiropractic we’re equipped to offer treatments which include:

Herniated Disc


A herniated disc can be the source of excruciating neck and back pain and is a common injury resulting from a rear-end collision.

what is a herniated disk

In between each vertebra is a soft disc designed to cushion the vertebrae and allow them to move smoothly. These discs can rupture or move out of place due to traumatic events like a car accident. In some cases, herniated discs — also called slipped discs — can push against surrounding nerves, causing numbness, tingling, pain, and weakness in the arms, legs, and other parts of the body.

Herniated discs are most common in the lower back (lumbar spine) but can also occur in the neck (cervical spine). Though they are a serious injury, they can usually be healed without surgical intervention.

If you’re suffering from a herniated disc, our team’s approach will vary based on the severity and location of the injury. We may use treatments including spinal manipulation, manual therapy, and physical therapy.

One other effective treatment for herniated discs is spinal decompression therapy, and this is one of our specialties at Rush Chiropractic. This therapy uses a computerized traction unit to gently straighten the spine. It increases the space between vertebrae and allows the displaced disc to slip naturally back into place. Spinal decompression therapy also increases blood flow to the injured area, allowing your injury to heal more quickly.

Muscle strain

A herniated disc is not the only form of back injury that can result from a rear-end collision. Auto accidents can cause other forms of back pain, which can be intermittent or persistent.

Muscle strain is another common injury that happens during rear-end collisions. Wrecks typically happen so quickly that the body compensates for the collision before the conscious mind knows what’s happening. Your body braces for impact, and muscles tighten. Unfortunately, this can lead to further injury and pain, since contracted muscles are more easily torn than relaxed ones.

Back pain can also arise as a complication from other injuries. A person who injures their leg in a wreck may have no initial back pain. Still, after weeks of muscle tension from compensating for the injured leg, their lower back may become inflamed.

Massage therapy relieves tension

At Rush Chiropractic, we offer massage therapy in addition to manual adjustments. This gentle approach relieves tension and stops the vicious cycle of compensatory injury. Your massage therapist will construct a treatment timeline that can help you feel good again without the use of pharmaceuticals.

Headaches and Migraines

Headaches can be insidious. And just like in John’s experience, they’re often the result of other injuries that happen in a rear-end collision.

But since the headaches sometimes don’t begin until weeks or even months after an accident, you may not make the connection to realize where your pain initially stems from.

Headaches are not all created equal

Headaches are not all created equal; some present as a dull ache, and others as stabbing pain. You may be suffering from a trauma headache or feeling the effects of a pinched nerve.

Muscle spasms can also lead to headaches. Whiplash causes muscles in the neck to contract in an effort to protect the spine. This abrupt, involuntary response can lead to spasms where the neck muscles continually tighten long after the accident is over, causing pain in the neck and head.

Concussions – when your brain collides with the inner wall of your skull – are another common injury in rear-end collisions. Concussions can cause moderate to severe headaches, in addition to nausea, vomiting, and fatigue.

Depending on the cause of your headaches, gentle, precise manipulation of the cervical spine can help restore alignment, promote healing, and reduce or eliminate headaches. Other treatment options include:

  • Electrical Nerve Stimulation
  • Hot and cold therapy
  • Manual therapy
  • Massage
  • Soft-tissue therapy

Since headaches can vary greatly depending on the cause, severity, and type of pain, it’s important to go to an expert who will help you uncover the source of your headaches instead of only treating the symptoms. When you visit Rush Chiropractic, we’ll take the time to understand the exact cause of your headaches and build a treatment plan that promotes healing at the root of the problem.

Arm and Wrist Injuries

If a driver is holding the steering wheel at the time of a rear-end collision, their arms and wrists often absorb some of the impact. This can cause injuries like sprained wrists, stress fractures in the arm, dislocated shoulders, and tendon damage. Airbags can also cause arm and wrist injuries depending on the driver’s position when the bags are deployed.

A chiropractor can treat many joint injuries with manipulation, which restores mobility to the joint and gives the injured tissues space to heal. At Rush Chiropractic, we also offer physical therapy and other treatments that can help you strengthen your arms and shoulders after a traumatic injury, which will help you recover faster and become less susceptible to future injuries.
