Is Chiropractic Care Safe – And Can It Cause a Stroke?

Let’s be honest

Most people only know two things about chiropractic:

  1. “They crack your back.”
  2. “Some people swear by it… some people swear at it.”

So when you ask:

“What is chiropractic, and how does it actually work to relieve pain?”

…what you’re really asking is:

  • “Is there real science behind this, or is it just fancy cracking?”
  • “What exactly are you doing to my spine and nerves?”
  • “Is this something I can feel confident using alongside other care?”

Grab a tea. I’ll walk you through this as if you were a close friend sitting in my clinic, asking, “Right, talk to me properly. No fluff.”

1. So… what actually is chiropractic?

Forget the stereotypes for a moment.

In plain language:

Chiropractic is a drug-free, hands-on approach that focuses on how your spine, joints, and nervous system move and function – with the goal of reducing pain and improving how you live your life.

Most people see a chiropractor for things like:

  • Low back pain
  • Neck pain
  • Sciatica (leg pain from the back)
  • Certain headaches (especially neck-related)
  • Shoulder, mid-back, or hip issues that feel “stuck” or restricted

A modern chiropractor doesn’t just “click things”.

They usually combine:

  • Assessment & diagnosis
  • Spinal and joint manipulation (the famous “adjustments”)
  • Gentle mobilisations (slower movements)
  • Soft-tissue techniques (muscle and fascia work)
  • Exercise and rehab
  • Ergonomic, sleep, and lifestyle coaching

Guidelines for spine pain now place spinal manipulation alongside other conservative therapies like exercise and education for low back pain, especially when it’s persistent.

So it’s not witchcraft. It’s one of the tools in the evidence-based conservative care toolbox.

2. What actually happens in a first chiropractic visit?

Let’s de-mystify the experience.

A good first visit typically looks like this:

a) A proper conversation, not a quick “where does it hurt?”

You’ll go through:

  • Your story – when it started, what makes it worse or better, what you’ve tried already
  • Your life – work, hobbies, sports, stress levels, sleep, general health
  • Your worries – “Is this a disc? Is it dangerous? Will I end up needing surgery?”

This is where we’re already narrowing down:

Is this likely a mechanical problem (joints, muscles, nerves, loading)…
or something more serious that needs medical investigation?

b) Physical and neurological examination

This isn’t just “touch toes and twist”.

It can include:

  • Posture and movement checks
  • Range-of-motion (how far things move – and where they hurt)
  • Muscle strength tests
  • Reflexes, sensation, nerve tension tests
  • Specific orthopaedic tests to provoke or ease symptoms

This is about pattern recognition:

  • Does your pain behave like non-specific mechanical low back pain?
  • Or like sciatica from a specific nerve root?
  • Or like a neck-related (cervicogenic) headache?

Serious “red flag” patterns (e.g. cancer, infection, fracture, cauda equina) should trigger immediate medical referral or imaging, not more manipulation.

c) Explanation + plan

By the end of the consult, you should hear something like:

  • “This looks like mechanical low back pain with some disc irritation and muscle guarding.”
  • “The good news: it doesn’t look like cancer, infection, or a serious nerve compression today.”
  • “Here’s what I recommend we do for the next 2–4 weeks, and what we expect to see change.”

You should understand:

  • What’s wrong (in simple terms)
  • What we’re going to do (techniques, frequency, home advice)
  • How we’ll know it’s working
  • When we’ll review and what happens if it doesn’t improve

If you don’t get that clarity, you’re allowed to say, “Can you explain that again in plain English?”

3. What is a chiropractic adjustment, really?

This is the famous bit everyone recognises visually but not conceptually.

A spinal adjustment (or high-velocity, low-amplitude manipulation) is:

A quick, precise movement applied to a specific joint, within a safe range, aimed at improving its motion and changing how the nervous system is firing in that area.

Key points:

  • High-velocity = quick
  • Low-amplitude = small movement, not yanking your head off
  • Usually accompanied by that “pop” (cavitation) – gas shifting in the joint

But chiropractors don’t just use thrusts. They also use:

  • Joint mobilisations – slow, rhythmical movements
  • Instrument-assisted adjustments – using a small device that delivers a gentle impulse
  • Soft-tissue techniques – muscle/trigger point/fascia work

In real practice, an adjustment is one tool inside a session, not the whole session.

4. OK but how does that relieve pain?

Great question – and this is where it gets interesting. It’s not just “bones back in place”.

Modern research suggests spinal manipulation works through multiple mechanisms:

  1. Mechanical changes
  2. Neurophysiological changes (spinal cord and brain)
  3. Psychosocial effects (expectation, context, therapeutic alliance)

Let’s unpack those.

4.1 Mechanical effects: joints and muscles

If a joint is stiff or not moving properly, you often get:

  • Local irritation
  • Protective muscle spasm
  • Altered movement patterns above and below

An adjustment or mobilisation can:

  • Increase joint range-of-motion
  • Temporarily reduce muscle tightness or guarding
  • Change joint loading and movement patterns

A 2023 randomized trial in chronic primary low back pain found that a 12-session course of spinal manipulation produced greater pain relief than a sham/control intervention, suggesting mechanical and/or neurophysiological benefits beyond placebo.

Another recent RCT (2025) looking at spinal manipulation in spine pain found that properly delivered high-velocity, low-amplitude techniques produced clinical improvements compared with some control approaches, supporting a real treatment effect.

So, at the very local level:

Joints move better → muscles calm down → less mechanical irritation.

5. What does the science say – does chiropractic actually work for pain?

Let’s talk outcomes, not just theory.

We’ll focus on spine pain and headaches, because that’s where the bulk of the research is.

5.1 Low back pain

Low back pain is the big one. It’s common, stubborn, and often multi-factorial.

A large 2019 BMJ systematic review of spinal manipulative therapy for chronic low back pain concluded:

  • Spinal manipulation is as effective as other recommended therapies (like usual medical care, exercise) for pain and function.
  • The size of the effect is modest on average – like most back pain treatments.
  • Serious adverse events appear to be rare.

A huge 2025 umbrella review of non-surgical treatments for low back pain found that only a handful of interventions (including exercise and spinal manipulation) showed small but real pain-relieving effects beyond placebo.

Recent clinical practice guideline overviews (2024) note that:

  • For subacute low back pain, spinal manipulation is one of the recommended non-drug options alongside exercise and staying active.
  • For chronic low back pain, guidelines commonly recommend:
    • Exercise
    • Education/self-management
    • Spinal manipulation
    • Sometimes acupuncture and psychological interventions.

The American College of Physicians guideline also recommends non-drug therapies such as spinal manipulation for acute and subacute low back pain before medications.

So the honest summary for low back pain:

On average, spinal manipulation gives small-to-moderate improvements in pain and function – about as good as the other main conservative options – and it’s one of the treatments that big guidelines say is reasonable to use, especially combined with exercise and education.

5.2 Neck pain

Neck pain is a bit less studied than low back pain, but similar patterns emerge:

  • Manual therapy (including manipulation and mobilisation), often combined with exercise, tends to produce modest improvements in pain and function.
  • NICE and other guidelines often recommend thoracic manipulation with neck exercises for some types of neck pain and mobility deficits.

Again, not magic – but a useful piece of the conservative-care puzzle, especially when integrated with movement and self-management.

5.3 Headaches (especially neck-related headaches)

Headache is broad; we’re mainly talking about:

  • Cervicogenic headache – thought to arise from structures in the neck
  • Some tension-type headaches

A 2020 systematic review found that for cervicogenic headache, spinal manipulation provides small but superior short-term benefits for pain, frequency, and disability compared with some controls, though long-term effects are less clear and evidence quality is variable.

More recent work (2024 RCT) showed cervical spine manipulation was more effective than thoracic manipulation and conventional physiotherapy in improving pain and disability in cervicogenic headache.

Older reviews also noted some benefit of manipulation for chronic headache disorders, but emphasised the need for better-quality trials.

So the honest takeaway:

For some headache types—especially neck-related headaches—chiropractic spinal manipulation can help some people, particularly in the short term and when combined with other strategies.

6. What chiropractic does not do

Let’s clear a few things up.

It does not “put bones back in” that are totally out of place

If your spine were truly “out of place” in the dramatic way some diagrams show, you’d likely be in an emergency department, not a clinic.

We’re dealing with:

  • Subtle alignment and movement changes
  • Joint stiffness or restricted segments
  • Muscle guarding and altered movement patterns

Not dislocated vertebrae floating around your body.

It does not cure every health problem under the sun

You’ll see claims online that adjustments:

  • Fix asthma
  • Cure gut diseases
  • Solve fertility issues

The reality:

  • There is insufficient high-quality evidence to say spinal manipulation directly treats most non-musculoskeletal conditions.
  • Any improvements people notice in those areas are usually indirect (less pain → better sleep → lower stress → better lifestyle choices).

Most evidence-based chiropractors today focus on musculoskeletal and neuromusculoskeletal problems – where the science is strongest.

It does not replace your GP, physio, or specialist

Chiropractic is part of the team, not a rival.

The best results often come when:

  • GPs handle red flags, medication, and medical referrals.
  • Physios or trainers support progressive rehab and conditioning.
  • Chiropractors contribute hands-on care, spinal/joint work, and movement coaching.

Different tools. Same goal: get you functioning and feeling better.

7. Who is a good candidate for chiropractic care?

You might be a good fit if:

  • Your main complaints are back, neck, joint or muscle pain
  • Pain clearly changes with movement, posture, or load
  • You don’t have red-flag signs (unexplained weight loss, fever, cancer history, serious trauma, cauda equina symptoms, etc.)
  • You’re willing to engage in exercise and lifestyle changes, not just passive treatment

You might need careful co-management or alternative plans if:

  • You have osteoporosis, inflammatory arthritis, or other conditions affecting bone integrity
  • You have significant neurological disease
  • You’re on blood thinners or have known vascular issues
  • Pain is accompanied by worrying systemic signs

A good chiropractor will:

  • Screen you properly
  • Adapt techniques
  • Refer or co-manage when needed

If they never refer or “don’t believe” in working alongside medicine, that’s a red flag.

8. What does an integrated chiropractic plan look like?

The best question you can ask yourself is not:

“Should I only see a chiropractor?”

…but:

“How could chiropractic fit into a bigger plan to get me out of pain and keep me there?”

A strong integrated plan usually includes:

  1. Education and reassurance
    • Understanding what’s going on, and what’s not going on (e.g., “This isn’t your spine crumbling”).

  2. Manual therapy

    • Adjustments, mobilisation, soft-tissue work
    • Used to reduce pain and stiffness enough that you can start moving more freely
  3. Exercise and rehab

    • Targeted strengthening and mobility work
    • Graded exposure back into the things you’ve been avoiding
    • Strong evidence that exercise is one of the best long-term tools for back pain and general MSK health

  4. Lifestyle and load management

    • Workstation and posture tweaks
    • Sleep, stress, and activity pacing
    • Gradually changing the habits that fed the problem in the first place

Spinal manipulation by itself can help – but research and guidelines are clear: it works best as part of a package that includes exercise and self-management.

9. Is chiropractic safe? (Short, honest version)

We covered stroke risk in detail in the previous blog, so here’s the quick, broader safety snapshot.

  • Minor side effects (soreness, stiffness, temporary headache) after spinal manipulation are relatively common, often starting within 24 hours and settling in a day or two.
  • Serious adverse events (like cauda equina syndrome, severe neurological issues, arterial dissection) are rare, especially in the context of low back pain manipulation; the 2019 BMJ review described them as uncommon and usually reported in case reports rather than large trials.
  • Recent RCTs totalling thousands of spinal manipulation sessions report no serious adverse events, only minor transient ones.

So in practice:

For most people with straightforward mechanical spine pain, spinal manipulation delivered by a trained clinician appears to have a good safety profile, with serious complications very rare, but not zero.

Your chiropractor should always:

  • Screen for red flags
  • Adapt techniques to your age, condition, and preferences
  • Discuss risks/benefits and alternatives so you can make an informed choice

10. How to choose a chiropractor you can trust

  • Here’s your mini checklist.

    Look for:

    • Proper registration with your country’s regulatory body
    • Willingness to explain your diagnosis and plan clearly
    • Use of guideline-consistent language (e.g., encouraging movement, exercise, self-management)
    • Collaboration with GPs, physios, and other professionals when appropriate
    • Time for questions and informed consent

    Be cautious if:

    • They promise to cure unrelated diseases with adjustments alone
    • They insist on full-spine X-rays for every new patient without clinical justification
    • They pressure you into huge long-term packages with no review points
    • They discourage you from seeing your GP or taking prescribed medications
    • Everything is framed in fear (“Your spine is degenerating unless you come forever”)

    You want someone who is:

    Confident but humble, skilled with their hands but also happy to not adjust if it’s not appropriate that day

    The bottom line (friend-to-friend)

    If you strip away the noise, chiropractic is simply:

    A way of helping sore, stiff, overloaded bodies move and feel better by combining hands-on work with smart movement and lifestyle changes.

    From the research we have right now:

    • For low back pain, spinal manipulation offers small-to-moderate improvements in pain and function and is one of the few non-surgical treatments with consistent evidence.
    • For neck pain and some headaches, it can help some people, especially short term, and especially when combined with exercise.
    • It works through a mix of mechanical, nervous system, and psychosocial mechanisms – not just “bones in/out”.
    • Serious complications appear to be very rare, while minor soreness is fairly common and usually short-lived.

    Is it a miracle cure? No.

    Is it snake oil? Also no.

    It’s a legitimate, evidence-supported option for many people with spine-related pain – especially when combined with exercise, education, and sensible lifestyle changes.

    And you always get to ask:

    “Does this make sense for me, in my situation, right now?”

    If you keep that question front and centre – and work with a chiropractor who welcomes it – you’re using chiropractic exactly the way modern science would want you to.

The bottom line (friend-to-friend)

If you’re living with back pain, neck tension, sciatica, headaches or just feel your body isn’t moving the way it should, you don’t have to put up with it or try to guess what’s wrong.
