If you’re dealing with back pain and considering chiropractic care, you may have wondered whether an adjustment could make things worse. For most people, the evidence suggests it doesn’t.
The risk isn’t zero, though, and it matters most for people whose herniated disc is already pressing hard on a nerve. It also depends on whether the chiropractor properly evaluated you before treatment and stopped and referred you when symptoms got worse.
This guide explains how a herniated disc works and what the research says about manipulation risks. It also covers which warning signs need emergency care, when a worse outcome after chiropractic treatment may raise legal questions in New York, and which deadlines apply.
Prior results do not guarantee a similar outcome.
What Is a Herniated Disc?
Cushioning discs sit between the vertebrae in your spine. Each has a tough outer ring and a softer inner core. A herniated disc happens when some of that inner material pushes beyond its normal boundary.
In the lower back, displaced disc material can press on or irritate nearby nerve roots. Common symptoms include:
Low back pain
Pain that runs through the buttock and down one leg, often called sciatica
Numbness, tingling, or burning in the leg or foot
Weakness, such as trouble lifting the foot, standing on your toes, or rising from a chair
Changes in reflexes
Less commonly, severe compression that affects bladder, bowel, sexual function, or sensation in the groin area
Not every herniated disc causes symptoms. A systematic review of spine imaging in people without back pain found disc protrusions in 29 percent of 20-year-olds and 43 percent of 80-year-olds who had no symptoms at all.
That matters later. A herniation seen on an MRI after an adjustment may have been there before, so imaging alone doesn’t show what caused it.
How Could an Adjustment Make Things Worse?
A classic chiropractic adjustment uses a high-velocity, low-amplitude thrust. This is a quick, controlled force applied to one part of the spine, often with a popping sound. When a nerve root is already irritated, that force could potentially:
Increase inflammation around the nerve
Trigger muscle spasms
Aggravate radiating leg pain
Add mechanical stress to a disc that’s already compressing a nerve
There’s also a less obvious risk. Worsening symptoms can be mistaken for normal soreness after treatment, which can delay the diagnosis of a more serious problem.
Someone with a herniated disc may tolerate gentler approaches better than forceful thrust manipulation. The specific technique used also matters when records are reviewed later.
Manipulation isn’t a proven way to “put a disc back in place.” The National Institutes of Health describes spinal manipulation as one of several options, alongside exercise, massage, and physical therapy, that can provide mild to moderate relief from low back pain. It isn’t a cure for nerve compression.
What Does the Medical Evidence Show?
Online stories about adjustments causing paralysis often overstate the risk. Here’s what the more reliable sources say:
Common side effects are minor. The NIH’s fact sheet on spinal manipulation for low back pain reports that the most common side effects, such as discomfort in the treated area, are minor and usually go away within one to two days.
Worsening a herniation appears unlikely. The same fact sheet states that for people whose pain comes from a herniated disc, low back manipulation appears to have a very low chance of worsening the herniation.
Cauda equina syndrome is extremely rare, and the link is uncertain. The fact sheet describes cauda equina syndrome as a possible, extremely rare complication of manipulation. It adds that it’s unclear whether manipulation actually causes it, since the condition usually occurs without manipulation.
A large 2026 study found no increased risk. A retrospective study of more than 134,000 matched adults compared people with lumbar disc herniation, stenosis, or radiculopathy who had chiropractic manipulation against those who had physical therapist-led exercise. It found no statistically significant difference in the rate of cauda equina syndrome between the two groups.
These findings have limits. Serious events are so rare that even large studies have trouble measuring them precisely. Observational research can’t prove there’s no risk for a particular patient, and published letters have raised questions about the 2026 study’s methods.
People also often seek chiropractic care because a disc problem is already getting worse. That makes it hard to tell whether a later decline was caused by treatment or would have happened anyway.
Some of the most widely reported serious complications, such as artery injury and stroke, involve manipulation of the neck. They are a different issue from treatment of the lower back.
Can You Sue a Chiropractor in New York?
New York courts recognize chiropractic malpractice claims. A claim doesn’t turn on the fact that you had a herniated disc and then an adjustment. It turns on whether the chiropractor departed from accepted chiropractic practice and whether that departure caused real harm. A claim generally requires proof of four things:
Duty. The chiropractor owed you a professional duty of care.
Departure. The chiropractor departed from the accepted standard of chiropractic care.
Causation. That departure caused or substantially contributed to an identifiable injury.
Damages. You suffered real harm as a result.
In Perez v. Fitzgerald, 115 A.D.3d 177 (1st Dep’t 2014), a patient saw a chiropractor for neck pain with numbness in both hands. The chiropractor relied on a radiologist’s MRI report without reviewing the films herself and adjusted the patient’s neck over later visits.
She did not order a second MRI. A spinal tumor was eventually found through a different provider. The jury found the chiropractor departed from accepted chiropractic practice by failing to refer the patient for a second MRI. The appeals court reinstated that verdict.
If a hospital or physician later missed a serious problem, such as cauda equina syndrome in the emergency department, that’s a separate question with its own rules. Our hospital malpractice page explains more about those claims.
What Are the Deadlines to File a Claim in New York?
The deadline depends on who treated you and how that care was arranged. Missing one can end a claim regardless of the facts.
Situation | Deadline | Law |
|---|---|---|
Chiropractor treating you on their own | Lawsuit generally within 3 years, as malpractice other than medical, dental, or podiatric malpractice | |
Treatment given at a physician’s direction or as part of a physician’s care, or claims against a physician or hospital | Lawsuit within 2 years and 6 months from the malpractice, or from the last treatment when treatment for the same condition is continuous | |
Treatment at a city, county, or other public facility | Notice of claim within 90 days, and a lawsuit within 1 year and 90 days | GML 50-e and 50-i |
Injured child | The deadline is generally paused until the child turns 18, with limits for claims under CPLR 214-a | CPLR 208 |
Perez v. Fitzgerald is the leading case on this split. The court held that the shorter medical malpractice deadline did not apply to a chiropractor who treated the patient independently. No physician had referred the patient, and the chiropractic care wasn’t part of any physician’s treatment. The claim was therefore timely under the three-year rule.
The court also explained why the line matters. Care provided at a physician’s direction can fall under the shorter deadline. One example it described involved a physical therapist who applied enough force to a patient’s back to herniate a disc. Because that therapy was part of the patient’s medical treatment, the shorter deadline applied.
Because the answer depends on how your care was arranged, it’s safest to act well before the shorter deadline. The clock generally runs from the treatment itself, not from when you later connect it to your symptoms.
What Compensation Can a Claim Include?
If negligence and causation are proven, the categories of compensation may include:
Past and future medical costs, including emergency care, imaging, surgery, and rehabilitation
Lost wages and reduced earning ability
Pain and suffering and loss of enjoyment of life
Costs tied to permanent weakness, nerve damage, bladder or bowel dysfunction, or other paralysis injuries
What a claim may include depends on the injury, the medical evidence connecting it to the treatment, and how the facts are weighed. A worse outcome alone isn’t enough.
What Are Your Rights as a Patient?
You can stop treatment at any time. If an adjustment makes your symptoms worse, you don’t have to continue. You can get a second opinion. This is especially important with new or worsening numbness or weakness.
You can get your records. New York law gives patients access to their own health records.
You can report a concern to regulators. Complaints about chiropractors and other licensed professionals go to the New York State Education Department’s Office of Professional Discipline at 1-800-442-8106.
The number is listed in the state’s patient rights guide. A complaint may lead to discipline, but it’s separate from a lawsuit and doesn’t pause any filing deadline.
Frequently Asked Questions
Does a herniation on an MRI after my adjustment prove the chiropractor caused it?
Not by itself. Disc herniations are common in people with no symptoms, so a herniation on a later MRI may have existed before treatment. Stronger evidence usually involves several pieces together. These include a clear change in symptoms right after a specific visit, such as new weakness or numbness, earlier imaging to compare against, and a medical expert’s opinion connecting the change to the treatment.
Is it normal to feel sore after a chiropractic adjustment?
Yes, mild soreness or tiredness is common. The NIH reports it usually fades within one to two days. New weakness, spreading numbness, numbness in the groin or inner thighs, or any change in bladder or bowel control is different. These aren’t normal soreness and call for prompt medical evaluation, not another adjustment.
Can I still have a claim if I signed a consent form?
Possibly. A consent form shows you were told about some risks, but it doesn’t permit treatment that falls below the standard of care. It also doesn’t excuse a failure to examine you properly or to refer you when warning signs appeared. Whether the form covered the risks that actually applied to your condition can matter too. The answer depends on the form, the records, and what happened during treatment.
What if my doctor referred me to the chiropractor?
It can affect both the analysis and the deadline. When chiropractic care is given at a physician’s direction or as part of a physician’s treatment, the shorter 2 years and 6 months deadline may apply instead of three years. The referring doctor’s own care may also be reviewed. Because the rules depend on how care was arranged, get legal advice early rather than relying on the longer deadline.
What if the emergency room missed cauda equina syndrome after my adjustment?
That can be a separate claim against the hospital or emergency physician. It would focus on whether saddle numbness, bladder symptoms, or leg weakness were recognized, and whether imaging and surgery happened in time. Medical malpractice deadlines generally apply to that claim. If the hospital is public, a 90-day notice of claim may be required.
Summing It Up
For most people, a chiropractic adjustment doesn’t make a herniated disc worse. Temporary soreness is common, and serious nerve complications are rare. The risk that does exist is concentrated in people with significant nerve compression or warning signs that weren’t evaluated.
