Herniated Disc From a Car Accident: Your Back Injury Claim Explained

Your back or neck has hurt since the crash, maybe with pain or numbness running into an arm or a leg, and now a doctor or an MRI report says “herniated” or “bulging” disc. Can a car accident cause that? Yes. MedlinePlus, the National Library of Medicine’s health site, says back injuries can result from “a sudden jolt such as a car accident,” and that a spinal disk can herniate or rupture “from injury or strain.” If you’re worried that an old back problem sinks your claim, that’s a common fear. The law’s answer: you can recover for the harm the crash added, though not for the condition you already had. What decides your claim is the proof.

MedlinePlus spells it “disk”; this guide uses the more common “disc.” Michigan’s rules are in boxes marked “In Michigan.”

Can a car accident cause a herniated disc?

Yes. MedlinePlus lists herniated disks among common back injuries, along with sprains, strains and broken vertebrae, and says back injuries can result from “a sudden jolt such as a car accident.” It also names car accidents as a common cause of neck pain.

Your spine is a stack of bones called vertebrae, separated by disks that cushion them and let you bend (MedlinePlus). A disk herniates, or slips, when all or part of it is forced through a weakened part of the disk. It can then press on nearby nerves and cause pain, numbness or weakness. Where it happens shapes the symptoms. By site, they may include (MedlinePlus):

• Lower back, the most common site: sharp pain in part of the leg, hip or buttocks, numbness in other parts, and sometimes a weak leg. Leg symptoms from pressure on the sciatic nerve are called sciatica, and a herniated disk is a common cause.
• Neck, the second most common site: pain when you move your neck, deep pain near the shoulder blade, or pain that moves into the arm and fingers, sometimes with numbness. For a neck sprain or strain (whiplash), see whiplash claims.

Only a doctor can tell which injury you have.

Can a car accident cause a bulging disc?

It can. MedlinePlus lists “bulging disk” among the other names for a herniated disk, with slipped, ruptured and prolapsed disk, so the same answer applies.

Disks also wear with age. MedlinePlus says that as you age, disks “break down or degenerate” and lose their cushioning, and the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the National Institutes of Health, calls this degenerative disc disease. So a scan taken after a crash may show years of wear next to something new, and the other side may blame your pain on an old back problem. The law has rules for that, below.

What if your back didn’t hurt until days after the crash?

Get checked anyway, and tell the doctor about the crash. MedlinePlus says herniated-disk pain “often starts slowly,” and that muscle weakness is sometimes not noticed until a provider examines you.

Some symptoms can’t wait. MedlinePlus says to go to a hospital or call 911 if numbness or tingling starts just after a head, neck or back injury or comes with weakness or an inability to move, or if you can’t control the movement of an arm or a leg or have lost bladder or bowel control. It says to contact a provider right away for back pain after a severe blow or fall. Our guide to delayed injury symptoms after an accident lists more warning signs.

Late-starting pain matters for the claim, too. Long gaps in treatment give the other side room to argue that you weren’t badly hurt, or that something else caused the problem, so tell every provider when each symptom started.

How do you prove the crash caused your herniated disc?

With medical records that tie the injury to the crash, and a timeline that holds together. In a crash claim you generally have to prove that the other driver was negligent (careless) and that this negligence caused your injuries. Michigan’s model civil jury instructions (the standard instructions judges read to jurors, cited as M Civ JI), for example, put that burden on the injured person (M Civ JI 36.06). The evidence that connects a disc herniation to a crash:

Keep your appointments. You’re expected to use ordinary care to limit your losses, which can include getting and following reasonable medical treatment; Michigan jurors, for example, are told not to compensate damages that resulted from failing to do so (M Civ JI 53.05).

What if you had back problems before the crash?

An old back problem doesn’t erase your claim. You can recover for the aggravation, meaning the added pain, disability and expenses the crash caused, though not for the condition you already had.

Under a common-law rule often called the eggshell skull rule, a defendant must “take the victim as they find them”: if the crash legally caused the injury, the person at fault is responsible for the resulting harm, even if most people wouldn’t have been hurt as badly (Cornell Law School’s Legal Information Institute). Michigan’s jury instructions show how this plays out:

The rule cuts both ways: jurors are told to award the damages “caused by defendant’s conduct alone” and to separate out the old condition when they can (M Civ JI 50.11). That’s why before-and-after evidence matters so much in a disc claim.

What does “degenerative” on an MRI report mean for your claim?

On its own, it doesn’t answer the legal question. Degenerative disc disease is the breakdown of disks that comes with aging (NIAMS), so a scan taken after a crash may show it whether or not the crash added anything. What the crash added shows in the before-and-after evidence, including any earlier imaging compared with the new. Tell your doctors about earlier back problems, so your records show both.

Can you sue for pain and suffering after a herniated disc?

In most states, yes, if you can prove another driver caused the crash and you file before the deadline. In a no-fault state, you can sue for pain and suffering only if your injury passes the state’s threshold, or if you kept the full right to sue in a state that lets drivers choose (Triple-I). The complete car accident lawsuit guide explains how fault and no-fault states differ, and our car, truck and motorcycle accident guides cover the rest.

What is the average settlement for a herniated disc from a car accident?

There isn’t a reliable one. Settlement terms typically aren’t made part of the public record (U.S. Bureau of Justice Statistics), so no “average herniated disc settlement” you find online can be checked against the full set of cases.

Why online herniated disc settlement figures mislead

• One label covers very different injuries. MedlinePlus says herniated-disk symptoms often go away or improve a lot over weeks to months, but some people need injections or surgery, some have long-term back pain even after treatment, and people in heavy-lifting jobs may need to change their job activities. An average blends all of them.
• You can’t see what’s counted. A figure with no named dataset or year doesn’t say which injuries, states or years it covers, or whether it’s before or after fees.
• Advertised results are chosen by the firm that publishes them, and each reflects its own facts.
• Formulas have no official basis. Calculators that multiply your medical bills by a number are rules of thumb. Michigan jurors, for example, are told that the amount for some losses “cannot be proved in a precise dollar amount” and that “the law leaves such amount to your sound judgment” (M Civ JI 50.01).
• State rules change what a settlement covers. A Michigan settlement with the at-fault driver’s insurer doesn’t include what PIP pays (MCL 500.3135(3)(c)), so it isn’t comparable to a settlement in an at-fault state.

What does drive the value of a disc claim?

Our guides to how to evaluate a personal injury claim and what actually decides a car accident settlement walk through the factors. For a disc injury, they come down to:

1. The injury and its treatment. Michigan jurors are asked to compensate each loss “taking into account the nature and extent of the injury” (M Civ JI 50.01). How long your symptoms lasted, and whether you needed therapy, injections or surgery, show up here.
2. The future. Future losses count when the evidence shows they’re reasonably certain, such as a surgery you’ll need later or work you won’t be able to do (M Civ JI 50.01).
3. What changed in your life. Pain, mental anguish and the loss of things you used to enjoy have no price list (M Civ JI 50.01, 50.02).
4. How clearly your records separate old from new (M Civ JI 50.11).
5. Fault and insurance. In Michigan, if you’re more than 50% at fault, you can’t recover pain-and-suffering damages at all, though a Michigan resident’s economic-loss claim is only reduced (MCL 500.3135(2)(b); M Civ JI 36.06). And a claim is only worth what can be collected, which for most injury claims means insurance.
6. What you’d keep after the lawyer’s fee, case costs and any liens come out.

Treatment decisions belong to you and your doctors. The claim should follow your care, never steer it.

What to do next

1. Get checked by a doctor, and go back if symptoms change. Tell every provider about the crash, when each symptom started and any earlier back or neck problems, and keep your appointments.
2. Build a before-and-after file. Keep imaging reports, therapy notes, work restrictions, bills and pay stubs, plus a dated journal of what you can’t do and the names of people who have seen the change.
3. Put your deadlines in writing. Every state sets a deadline to sue. In Michigan, give your auto insurer written notice of your injury within one year of the crash (MCL 500.3145(1)). Most lawsuits against an at-fault driver must be filed within three years (MCL 600.5805(2)).
4. Hold off on signing. You don’t have to give the other driver’s insurer a recorded statement. Read any medical authorization before you sign it, and narrow it to what the claim needs. Don’t sign a release until you know how badly you’re hurt. See talking to insurance adjusters.
5. Get a free case review, and the fee in writing. Get a free case review, or in Michigan, compare injury lawyers near you. Before you hire anyone, get the fee agreement in writing.

What waiting can cost

• Your right to sue. The clock usually starts when you’re hurt, not when you learn how badly. In Michigan, the three-year deadline runs from the injury, not from the day a scan finds the disc: a claim accrues when the wrong is done, regardless of when the damage shows up (MCL 600.5805(2), 600.5827).
• PIP benefits. Without written notice or a payment within one year of the crash, a lawsuit for PIP benefits can be barred (MCL 500.3145(1)).
• A release signed too soon. Disc symptoms often improve over weeks to months, but some people need injections or surgery (MedlinePlus). A signed release generally ends the claim for good, even if the injury turns out to be worse.

What a good outcome looks like

Your records tell one consistent story: what your back was like before the crash, what changed after it, and the care that followed, so an argument about an old condition meets evidence, not guesses. Your medical bills go to whoever owes them, and if you settle, the amount reflects your injury, your treatment and what’s still ahead, not an average from someone else’s case. From worrying that an old back problem sank your claim to knowing what the law covers, what your records show and what your case needs.
