Is Chiropractic Safe? Risks, Soreness and Red Flags
Post-adjustment soreness is common and expected. Serious adverse events are rare — rare is the honest word, not impossible. This article names the real contraindications, explains why chiropractors are not registered with the Malaysian Medical Council and what registration they do hold, and lists the warning signs that mean you should see a doctor first.
The Questions People Actually Have About Chiropractic Safety
The forum debates about chiropractic safety are not subtle. People are not asking whether they should take a painkiller. They are asking whether this whole practice is legitimate, whether they could be hurt, and whether the practitioner they are booking with is accountable to anyone at all.
Three posts, across three different Lowyat.net threads, stand in for the whole argument. One: “Chiropractor = scam. Why do people love to willligly get scammed.” Two: “not regonize by MMC.” Three: “after a few sessions disc kena compacted.”
Each of these is a different concern and deserves a different answer. Waving them away with reassurances converts nobody and should not. The honest approach is to concede what is true, correct what is not, and be specific about what the risks actually are.
What Is Normal After an Adjustment
Post-adjustment soreness is common and expected. This is not a warning sign — it is the same kind of soreness you get after unfamiliar exercise, and it typically resolves within one to two days.
You may also hear a pop or crack during the adjustment. That is gas releasing from the joint capsule, not bone moving on bone, and its absence does not mean the adjustment failed. Some people find the sound alarming on first encounter; understanding what it is tends to resolve that quickly.
What is not normal: soreness that gets significantly worse rather than better over two days, new neurological symptoms such as numbness or tingling in a limb, or any loss of bladder or bowel control after an adjustment. These would warrant a call to your doctor the same day.
The Real Contraindications
Chiropractic adjustment is not appropriate for everyone. The assessment exists partly to identify the conditions that make it unsafe — and when those conditions are found, the right answer is a referral, not an adjustment. The conditions that contra-indicate spinal manipulation include:
Structural and bone conditions
- Certain fractures — acute or unstable vertebral fractures are an absolute contraindication to manipulation at that level
- Bone disease that weakens the vertebrae, including some presentations of osteoporosis and bone tumours
- Infection of the spine
Inflammatory and vascular conditions
- Inflammatory arthritis in an active phase — including rheumatoid arthritis during a flare, when the ligaments around the joint are already compromised
- Some vascular conditions affecting the arteries supplying the brain, particularly relevant to cervical manipulation
- Acute disc herniation with progressive neurological signs — numbness, weakness, or reflex changes that are getting worse rather than stable
This is not a complete list — the assessment is what determines whether your specific presentation is safe to treat, and a practitioner who skips that assessment is not practising safely. At Trinity, the Gonstead protocol requires multiple independent findings to agree before any adjustment is made. When the findings suggest something that adjustment cannot help, or could harm, the answer is a referral.
Presentations That Need a Doctor First
Some symptoms that get described as “back pain” or “neck pain” are not musculoskeletal problems. They are warning signs of something that needs medical investigation before any manual therapy, and any competent chiropractor will tell you so. Book a doctor the same day, not a chiropractor, if your pain is accompanied by:
- Unexplained weight loss
- Fever or night sweats alongside the pain
- Loss of bladder or bowel control
- Progressive weakness in a limb that is getting worse, not staying stable
- Pain following a significant trauma (fall, car accident) that was not investigated
- A history of cancer, with new back pain that came on without a clear mechanical cause
These are called red flags in clinical screening not because they are certainly serious but because they need to be ruled out. A chiropractor who adjusts you without asking about them is not protecting you; a chiropractor who does ask and refers you when the answers are wrong is doing exactly what the role requires.
The MMC Point: What It Actually Means
The forum post saying chiropractors are “not recognised by the MMC” is factually accurate. It is also not the indictment it is presented as.
The Malaysian Medical Council registers medical doctors. Chiropractors are not medical doctors. The MMC’s Annual Practicing Certificate system covers practitioners under the Medical Act 1971 — a different piece of legislation, for a different profession. Saying a chiropractor is not on the MMC register is like saying a pharmacist is not on the Bar Council roll. Both are accurate. Neither is an indictment.
Chiropractors in Malaysia are regulated under a different instrument entirely: the Traditional and Complementary Medicine Act 2016. Since 1 March 2025, that Act has required every practising chiropractor in Malaysia to be registered and to hold a current Annual Practising Certificate. Registration is with the Ministry of Health, through its Division of Traditional and Complementary Medicine. Chiropractic is one of the practice areas that Division recognises, and Malaysia has regulated T&CM practitioners nationally since the Act was gazetted in 2016.
How to check a practitioner yourself: ask the clinic for the practitioner’s full registered name and Annual Practising Certificate number, then confirm both against the register held by the Ministry of Health’s Division of Traditional and Complementary Medicine. What you are confirming is Pengamal Tempatan status with AKTIF standing, and an Annual Practising Certificate that is current rather than expired. A clinic that will not give you the name and the number is the answer to the question. Both practitioners at Trinity — Dr. Tan Yen Qi and Dr. Bernice Wong, both BSc (Hons) Chiropractic from IMU University Malaysia — hold AKTIF status with APCs valid into February 2027. Their registration details are published on the chiropractic in Puchong hub page so you can verify them before booking.
Serious Adverse Events: What the Evidence Shows
The most serious adverse event associated with cervical (neck) manipulation is vertebral artery dissection — a tear in the artery wall that can cause a stroke. This is rare. Published estimates vary, but the range consistently sits at the level of one in several hundred thousand to one in several million cervical manipulations.
That does not mean the risk is zero. It means the risk is low enough that most practitioners and most guidelines consider cervical manipulation appropriate for most patients presenting with neck pain — but not all patients, which is why the vascular screening questions in the assessment exist.
The claim that “after a few sessions disc kena compacted” — that is, that chiropractic causes disc damage — is not supported by the evidence. Disc compression from spinal manipulation has not been demonstrated in clinical studies. What is true is that a disc problem can be made worse by manipulation delivered to the wrong level or without adequate screening — which is the argument for assessment before adjustment, not an argument against adjustment itself.
Authority Reference: The Annual Practicing Certificate system for medical practitioners in Malaysia is administered by the Malaysian Medical Council. Chiropractors are registered under a separate instrument — the Traditional and Complementary Medicine Act 2016 — and are not listed on the MMC register. Both systems require their respective practitioners to hold current annual certificates.
Common Questions About Chiropractic Safety
What people ask before deciding whether to book a first appointment.
Yes, mild soreness for one to two days is common and expected — similar to how muscles feel after unfamiliar exercise. This is not a warning sign. What would be a warning sign: soreness that gets significantly worse rather than better after 48 hours, new numbness or tingling in a limb, or any loss of bladder or bowel control. Those symptoms warrant a call to your doctor the same day, not a follow-up adjustment.
People with certain fractures, bone disease, inflammatory arthritis in an active phase, some vascular conditions, and presentations with progressive neurological signs should not be adjusted until those conditions are assessed and either ruled out or managed. The first-visit assessment exists partly to identify these. If your findings put you in one of those groups, the correct outcome is a referral, not an adjustment, and a practitioner who does not screen for these is not protecting you.
The claim that adjustment causes disc compression is not supported by evidence. What is true is that manipulation delivered without adequate screening, or targeted at the wrong level, can aggravate a disc problem. This is the argument for thorough assessment before adjustment, not an argument against the treatment itself. A disc problem identified in the assessment may also be a reason to use a different approach — such as motorised spinal decompression rather than manual manipulation.
No — and that is not a gap. The Malaysian Medical Council registers medical doctors under the Medical Act 1971. Chiropractors are not medical doctors; they are registered under a different instrument, the Traditional and Complementary Medicine Act 2016, administered by the Ministry of Health. Since 1 March 2025, every practising chiropractor in Malaysia must be registered and hold a current Annual Practising Certificate under that Act. The register is the one held by the Ministry of Health’s Division of Traditional and Complementary Medicine, not the MMC.
Ask the clinic for the practitioner’s full registered name and Annual Practising Certificate number, then check them against the register held by the Ministry of Health’s Division of Traditional and Complementary Medicine. You are looking for Pengamal Tempatan status with AKTIF standing and an APC that is current, not expired. If a clinic will not publish or supply its practitioners’ names and registration numbers, you cannot verify this before booking — which is exactly why those details are published here.
No. The sound is gas releasing from the fluid inside the joint capsule — a process called cavitation. It is not bone moving on bone, and it does not indicate anything has been displaced. The absence of the sound does not mean the adjustment failed. Many patients who found the sound alarming on their first visit describe it as unremarkable after a few sessions, once they understand what it is.
See a doctor first — the same day, not as an eventual step — if your pain is accompanied by unexplained weight loss, fever or night sweats, loss of bladder or bowel control, a limb that is progressively getting weaker, pain that followed a trauma and was not investigated, or a history of cancer with new back pain that has no clear mechanical cause. These are clinical red flags. They do not mean something is certainly wrong, but they need to be ruled out before any manual therapy begins.
Rare is the honest word. The most serious adverse event associated with cervical manipulation is vertebral artery dissection, which can cause a stroke. Published estimates consistently place this at the level of one in several hundred thousand to one in several million cervical manipulations. That is not zero, which is why the vascular screening questions exist in the assessment. The risk is low enough that most clinical guidelines consider cervical manipulation appropriate for most patients with neck pain — but the assessment, not reassurance, is what determines whether a specific patient is in the appropriate group.
