Injections for Pain: What's Out There and How to Think About Your Options
In a Hurry? There isn't one "injection" — there are several different types (corticosteroid, PRP, prolotherapy, trigger point, and more), each with different goals, evidence, and best-use cases. None of them fix the underlying mechanical problem on their own, which is where a comprehensive approach, including chiropractic and rehab, comes in.
Injections come up a lot in conversations with patients dealing with stubborn pain — usually because someone else recommended one, or they saw an ad, or they're just tired of hurting and want to know what their options are. So let's break down what's actually out there, in plain language.
Corticosteroid injections
These are probably the most common and the ones most people mean when they say "we got a shot for our pain." A corticosteroid is a powerful anti-inflammatory medication injected directly into a joint or around an irritated structure, like a bursa or nerve root. They can be very effective for short-term relief of inflammation-driven pain, and there's decent research behind them for conditions like joint arthritis flares or specific nerve compression issues.
The catch: they treat inflammation, not the underlying mechanical cause, and there's some research suggesting repeated corticosteroid injections into the same joint over time may accelerate cartilage breakdown. They're a useful tool, not a long-term strategy on their own.
PRP (Platelet-Rich Plasma)
PRP involves drawing your own blood, concentrating the platelets (which are rich in growth factors), and injecting that concentrate into an injured area — often tendons, ligaments, or joints. The theory is that it may stimulate your body's own healing response.
Research on PRP is genuinely mixed depending on what's being treated. Some conditions, like certain tendon injuries (tennis elbow, for example), have decent supportive evidence. Others are still fairly inconclusive. It's a reasonable option to discuss with a specialist for the right condition, but it's not a guaranteed fix, and it's often not covered by insurance.
Prolotherapy
Prolotherapy involves injecting an irritant solution (often a dextrose solution) into ligaments or tendons to trigger a localized inflammatory response, which theoretically stimulates tissue repair and increased stability. It's used most often for chronic ligament laxity or joint instability. The evidence base is smaller and more mixed than PRP, but some patients with specific chronic instability issues report good results.
Trigger point injections
These are typically a small amount of local anesthetic (sometimes with a corticosteroid) injected directly into a tight, irritable knot of muscle — a trigger point. They can provide fairly quick relief for muscular pain, though the relief isn't always long-lasting without also addressing why that trigger point developed in the first place.
Our honest take
We're not against injections — for the right condition, they can genuinely help, sometimes as a bridge that reduces pain enough to let you actually do the rehab work that fixes the underlying problem. But we do think they get oversold as a standalone fix. A shot can calm things down temporarily; it usually can't correct a movement pattern, a joint restriction, or a strength imbalance that's driving the pain in the first place.
If you're considering an injection, it's worth asking your provider what the injection is actually meant to accomplish, and what the plan is for addressing the underlying cause alongside it.
FAQs
Are corticosteroid injections bad for you? They're a useful tool for short-term inflammation relief, but there's some evidence that repeated injections into the same joint over time may accelerate cartilage wear. They're generally best used sparingly and alongside a broader treatment plan, not as a repeated standalone fix.
Does PRP actually work? It depends on the condition being treated. Research supports PRP reasonably well for certain tendon injuries, but evidence is more mixed for other uses. It's worth discussing your specific condition and the current evidence with a specialist before deciding.
How long does relief from a trigger point injection last? It varies a lot by person and by what's causing the trigger point in the first place. Some people get lasting relief; others find it returns unless the underlying cause — like a postural habit, muscle imbalance, or repetitive strain — is also addressed.
Should I try chiropractic care before getting an injection? It depends on your specific condition, but for a lot of mechanical, movement-related pain, addressing joint restriction and muscle imbalance first (or alongside an injection) tends to lead to more lasting results than the injection alone.
