Image guidance reduces uncertainty around needle placement, but no injection is risk-free and no procedure guarantees benefit.
Common or usually minor effects
- Brief pain from local anaesthetic or needle placement.
- Temporary soreness, bruising or a small amount of bleeding.
- A short-lived pain flare after the injection.
- Dizziness, nausea or a vasovagal reaction.
- Temporary numbness or weakness from local anaesthetic.
Medication-related effects
Corticosteroid can temporarily raise blood glucose and may cause flushing, sleep disturbance, mood change or transient blood-pressure effects. Repeated or poorly targeted steroid exposure can affect tissues and should be considered in the context of the diagnosis, previous injections and cumulative treatment plan.
Local skin or fat thinning and colour change can occur if steroid is deposited superficially. Direct injection into tendon substance may weaken tissue, which is one reason accurate target selection matters.
Uncommon but important risks
- Infection in the skin, soft tissue, joint, spine or deeper target.
- Bleeding or haematoma, particularly in patients with clotting disorders or blood-thinning medication.
- Allergic reaction to contrast, local anaesthetic, antiseptic, dressing or injected medication.
- Nerve irritation or injury.
- Unintended injection into a blood vessel or another structure.
- Dural puncture and low-pressure headache after selected spinal procedures.
- Pneumothorax for procedures close to the lung.
- Rare serious neurological complications from spinal procedures.
Why an injection may not work
- The injected structure was not the main source of symptoms.
- Several structures are contributing to the pain.
- The pathology is mechanical or structurally advanced rather than primarily inflammatory.
- The medication provides only temporary suppression of inflammation.
- Rehabilitation, load modification or broader medical treatment is still required.
- The condition needs surgical or specialist management.
A procedure is part of a pathway
The best use of an image-guided injection is usually within a broader plan that includes diagnosis, appropriate imaging, clinical review and rehabilitation. Repeating an injection without reviewing why the previous treatment failed may expose the patient to risk without improving the treatment strategy.
| Imaging guidance can confirm delivery to the intended target. It cannot prove in advance that the target is the cause of pain or that the injected medication will create lasting benefit. |

Frequently Asked Questions
For other FAQs please visit our FAQs page
Are serious complications common?
No. Most image-guided injections are completed without serious complication, but rare events can be significant. The consent discussion should reflect the exact procedure and anatomical region.
Is it safe to have repeated steroid injections?
There is no single safe number for every patient and target. The dose, interval, tissue, diabetes, bone health, previous response and alternatives should be reviewed before repeating treatment.
Does no response mean the procedure was inaccurate?
Not necessarily. A technically accurate procedure can fail because the target was not the main pain source or the pathology does not respond to that medication.
