Chiropractic vs Cortisone Shots: What the Research Actually Says About Long-Term Pain Relief

What cortisone injections actually do inside your body

A cortisone injection (technically a corticosteroid injection) delivers a synthetic version of cortisol directly into an inflamed area. The drug suppresses the local inflammatory response. White blood cells slow down. Swelling drops. Pain receptors stop firing as hard.

That is the good part. Pain decreases within 24 to 72 hours. For some patients, the relief lasts weeks. For others, it lasts months.

Here is what the injection does not do. It does not change the position of a restricted joint. It does not restore motion to a stiff spinal segment. It does not retrain a muscle that has been guarding for three months. It does not address the mechanical reason your body created inflammation in the first place.

Inflammation is not random. It is a response. Your body inflames tissue because something is irritating it. A disc pressing on a nerve root. A facet joint grinding because the segment above it is locked. A tendon rubbing under a bone because the shoulder blade is not moving right. Remove the irritant and the inflammation resolves on its own. Suppress the inflammation without removing the irritant and it comes right back.

Cortisone turns down the alarm. It does not put out the fire.

What a chiropractic adjustment actually does

A chiropractic adjustment applies a specific force to a joint that is not moving through its normal range. The goal is to restore segmental motion. When the joint moves properly again, three things happen in sequence.

1. Mechanical decompression. The joint surfaces separate slightly. This takes pressure off the structures getting compressed: disc material, nerve roots, joint capsule, surrounding ligaments. A 2013 MRI study in the journal Evidence-Based Complementary and Alternative Medicine showed measurable disc height changes after spinal manipulation in patients with lumbar disc herniation.
2. Neurological reset. The adjustment fires a burst of proprioceptive input into the central nervous system. Mechanoreceptors in the joint capsule (types I, II, and III) send fast signals that override the pain loop. This is why patients frequently feel immediate relief even before any tissue healing has occurred. It is a neurological effect, not a structural cure.
3. Muscle relaxation. When the joint restriction clears, the muscles that were guarding it release. The protective spasm drops. Range of motion returns. This is the full mechanism behind what an adjustment does to your spine.

Unlike cortisone, the adjustment addresses the mechanical cause. The tradeoff is that it requires the patient to participate: come back for follow-up visits, do the home exercises, modify the aggravating activity. Cortisone asks nothing of the patient except to hold still for 30 seconds.

What the research says: head-to-head comparisons

The evidence base for this comparison is substantial. Here are the studies that matter most.

Side-by-side comparison: chiropractic vs cortisone

When cortisone is the right choice

I am not anti-cortisone. There are clinical scenarios where an injection is the best first move.

• Frozen shoulder (adhesive capsulitis). The joint capsule is so inflamed and thickened that it physically will not move. An injection into the glenohumeral joint reduces the capsular inflammation enough to allow mobilization. Without the injection, some frozen shoulders stay frozen for 12 to 18 months.
• Acute bursitis. Trochanteric bursitis (hip), subacromial bursitis (shoulder), or olecranon bursitis (elbow) that is hot, swollen, and painful at rest. The bursa needs chemical calm-down before manual therapy makes sense.
• Severe radicular flare. A patient with an acute disc herniation producing severe leg pain, muscle weakness, or loss of reflexes may benefit from an epidural steroid injection to reduce nerve root inflammation enough to begin rehabilitation. This is a bridge, not a solution.
• Autoimmune joint inflammation. Rheumatoid arthritis flares, psoriatic arthritis, or other autoimmune conditions where the inflammation is systemic, not mechanical. Chiropractic does not treat autoimmune disease.

If you are dealing with any of these patterns, see your physician or a specialist. Knowing when to see a chiropractor versus a doctor is the first question to answer.

When chiropractic is the better choice

For the majority of musculoskeletal complaints, especially those involving the spine, the evidence favors manual therapy as the starting point.

• Mechanical low back pain. Joint restriction, facet syndrome, SI joint dysfunction, muscle spasm from segmental hypomobility. This is what chiropractic was built for.
• Neck pain and cervicogenic headache. Tension headaches that trace back to the neck respond well to cervical adjustment and soft tissue work. Cortisone into the neck carries higher risk and is rarely indicated for mechanical neck pain.
• Chronic pain that keeps coming back. If you have had 2 or 3 cortisone injections for the same problem and the pain returns every time, the injection is not failing. The underlying mechanical problem is never being addressed. This is the pattern behind pain that keeps returning.
• Post-surgical stiffness. Patients who have had spinal surgery but still have restricted segments above or below the surgical site. The surgery fixed the structural pathology. The remaining stiffness is a joint mobility problem.
• Sports and activity-related pain. Deadlift back strain, running knee pain, CrossFit-related dysfunction, or pickleball injuries. These are mechanical overload problems, not inflammatory diseases.

The hidden cost of repeated cortisone injections

Most patients do not hear this from the doctor ordering the injection. Corticosteroids, when injected repeatedly into the same tissue, cause measurable structural damage over time.

• Tendon weakening. A 2019 systematic review in the British Journal of Sports Medicine found that corticosteroid injections for tendinopathy provided short-term pain relief but were associated with worse long-term outcomes and increased risk of tendon rupture compared to exercise therapy and watchful waiting.
• Cartilage degeneration. A 2017 randomized trial published in JAMA (McAlindon et al.) found that repeated intra-articular corticosteroid injections in knee osteoarthritis resulted in significantly greater cartilage volume loss over two years compared to saline injections. The cortisone group lost more cartilage and did not have better pain outcomes.
• Local tissue atrophy. Fat pad atrophy and skin thinning at the injection site are well-documented effects of repeated steroid injections. This is why most physicians limit injections to 3 to 4 per year per joint.

This does not mean one cortisone injection will destroy your joint. It means that relying on cortisone as a long-term management strategy, rather than addressing the underlying cause, has a documented cost.

When both approaches work together

The smartest approach for some patients is both. A cortisone injection calms the acute inflammation enough that the joint can be moved. Then chiropractic care and rehabilitation address the mechanical cause so the inflammation does not return.

This is common with:

• Frozen shoulder: Injection to reduce capsular inflammation, followed by mobilization and stretching to restore range of motion.
• Acute sciatica with severe nerve irritation: Epidural to calm the nerve root, followed by spinal manipulation and core rehabilitation to take pressure off the disc. Sciatica that keeps coming back usually means the mechanical problem was never corrected.
• Severe hip bursitis: Injection to reduce the bursa, followed by hip mobilization and gait correction to stop the irritation cycle.

If you have had an injection and the problem returned, that does not mean the injection failed. It means the next step is addressing the mechanical cause. That is where chiropractic fits.

What I tell my patients at Vanguard Chiropractic

When someone walks into Vanguard Chiropractic and tells me they are deciding between a cortisone shot and coming to see me, I ask one question: is this an inflammatory problem or a mechanical problem?

If their knee is hot, swollen, and they have a history of rheumatoid arthritis, I send them to their rheumatologist. If their lower back seized up after bending to pick up a box and they cannot straighten up, that is a joint restriction. An injection will not fix a locked facet joint. An adjustment will.

Most of the patients who walk through my door have already tried the injection route. They got relief for three weeks, then the pain came back. They got another injection. It lasted two weeks. Then a third. It lasted five days. By that point, the cortisone is not failing. Their body is telling them the mechanical problem was never fixed.

That is when chiropractic makes the most sense. Not as an alternative to cortisone, but as the logical next step when cortisone has done everything it can do.
