A steroid shot may start reducing pain and inflammation within a few days, although some people may take 1–2 weeks to notice the full benefit. The timing varies depending on the condition, injection site and individual response. At Alton Pain Clinic, ultrasound-guided corticosteroid injections are used to help ensure accurate placement where appropriate.
How Long Does a Steroid Shot Take to Work?
A steroid injection does not always provide immediate relief.
The corticosteroid works by reducing inflammation in the treated area. Some patients begin to notice improvement within a few days, while the full effect may take one to two weeks.
The exact timing varies from person to person.
If the injection contains a local anaesthetic, you may experience some pain relief shortly after the procedure. This effect is temporary and can wear off before the corticosteroid has had time to take effect.
Steroid Injection Pain Relief Timeline
A general timeline may look like this:
Time after injection | What you may experience |
Immediately after | Some temporary relief may occur if local anaesthetic is included |
First 24–48 hours | Mild soreness or temporary irritation may occur |
First few days | The corticosteroid may begin reducing inflammation |
3–7 days | Some patients begin noticing clearer improvement |
1–2 weeks | The full benefit may become more apparent |
This is a general guide rather than a guarantee. Your response will depend on the condition and area being treated.
Why Doesn't a Steroid Injection Work Immediately?
The steroid medication needs time to produce its anti-inflammatory effect.
A local anaesthetic, when used, can provide more immediate but short-term pain relief. Once the anaesthetic wears off, you may notice your original pain again before the corticosteroid begins to take effect.
This can sometimes make patients think that the injection has not worked when, in fact, the corticosteroid simply needs more time.
Can Pain Get Worse Before a Steroid Injection Works?
Yes. Some patients experience a temporary increase in pain after a corticosteroid injection.
This is known as a post-injection flare. It may cause temporary soreness or increased pain around the treated area and generally settles within a few days.
If pain becomes severe, continues to worsen or is accompanied by other concerning symptoms, seek medical advice.
How Long Does the Pain Relief Last?
The duration of pain relief varies considerably.
Depending on the condition and individual response, some patients may experience relief for several weeks, while others may experience improvement for several months.
A steroid injection is primarily intended to reduce inflammation and symptoms. It does not necessarily correct the underlying cause of a condition.
What Affects How Quickly a Steroid Injection Works?
Several factors can affect how quickly you notice improvement.
Several factors can affect how quickly you notice improvement.
Different musculoskeletal conditions respond differently to corticosteroid treatment.
The severity of inflammation
The degree and duration of inflammation can affect the response to treatment.
The injection site
The joint, tendon, bursa or soft tissue being treated can influence the response.
Individual response
Every patient responds differently. Some people notice improvement quickly, while others need more time.
Accurate injection placement
Ultrasound guidance allows the clinician to visualise the relevant structures and guide the needle towards the intended treatment area.
How Are Steroid Injections Given at Alton Pain Clinic?
At Alton Pain Clinic, treatment starts with an appropriate assessment of your symptoms.
Where clinically appropriate, ultrasound can be used to examine the affected area and guide the injection.
During an ultrasound-guided injection, the clinician can see the relevant structures in real time while guiding the needle towards the intended treatment site.
This allows the treatment to be targeted to the area being assessed.
What Should You Do After a Steroid Injection?
Aftercare depends on the area treated and your individual circumstances.
You may be advised to:
- Take it easy for the first 24–48 hours
- Avoid strenuous exercise involving the treated area
- Gradually return to normal activities
What If My Steroid Injection Hasn't Worked After Two Weeks?
If you have not noticed improvement after the expected timeframe, speak to your clinician.
The lack of improvement may mean that:
- The underlying condition is not responding to corticosteroid treatment
- Another cause of pain needs to be considered
- Additional treatment may be appropriate
- A different management approach may be more suitable
A further assessment can help determine the next step.
