The duration of pain relief can vary depending on the condition being treated, the area injected, the severity of inflammation, and the individual response to treatment.
How Long Does Pain Relief from a Steroid Injection Last?
For many patients, steroid injections may provide relief for:
- Several weeks
- Several months
- Occasionally longer-term relief
Some people begin noticing improvement within a few days, while others may take 1–2 weeks to experience the full effect.
In many cases, pain relief lasts between 6 weeks and 6 months, although this varies significantly depending on the underlying condition.
| Condition / Area Treated | Typical Duration of Relief |
|---|---|
| Knee arthritis injection | 6 weeks to 6 months |
| Shoulder bursitis injection | Several weeks to several months |
| Trigger finger injection | Several months or longer |
| Frozen shoulder injection | Weeks to months |
| Sciatica steroid injection | Variable depending on severity |
| Tendonitis injections | Weeks to several months |
Factors That Affect How Long a Steroid Injection Lasts
Several factors influence the duration of symptom relief after a corticosteroid injection.
The Condition Being Treated
Some conditions respond better than others.
For example:
- Bursitis and trigger finger often respond very well
- Advanced arthritis may provide shorter-term relief
- Tendon-related conditions can vary significantly
Severity of Inflammation
Mild or early inflammation may respond for longer periods compared to severe chronic inflammation.
Activity Levels After Injection
Following aftercare advice may help maximise the benefits of treatment. Excessive activity immediately after an injection may temporarily aggravate symptoms.
Accuracy of Injection Placement
Ultrasound guided steroid injections can improve accuracy by ensuring medication is delivered precisely to the affected area.
How Long Do Steroid Injections Last in Different Areas?
Knee Steroid Injection
A cortisone injection in the knee may provide relief for several weeks to several months, particularly in patients with arthritis or inflammation.
Shoulder Steroid Injection
Steroid injections for shoulder pain, bursitis, or frozen shoulder may provide relief lasting from a few weeks to several months.
Trigger Finger Steroid Injection
Many patients experience significant improvement after a trigger finger injection, although symptoms can sometimes return over time.
Sciatica Steroid Injection
Steroid injections for sciatica aim to reduce inflammation around irritated nerves. Relief duration varies depending on the cause and severity of nerve irritation.
When Does a Steroid Injection Wear Off?
Symptoms may gradually return as the anti-inflammatory effects of the medication reduce over time.
Some patients require:
- repeat injections
- physiotherapy
- exercise rehabilitation
- additional treatments depending on the underlying condition
A clinician can advise whether repeat injections are appropriate.
What If My Steroid Injection Does Not Last Long?
If pain relief is short-lived, possible reasons include:
- Severe underlying arthritis
- Chronic tendon damage
- Ongoing mechanical irritation
- Incorrect diagnosis
- Advanced joint degeneration
Further assessment may be recommended if symptoms persist.
Can You Have Repeat Steroid Injections?
Repeat steroid injections may sometimes be recommended, although there are limits to how frequently injections should be performed in the same area.
Treatment plans are tailored individually depending on:
- the condition being treated
- previous response to injection
- overall joint or tendon health

Frequently Asked Questions
How quickly does a steroid injection start working?
Some patients notice improvement within 24–72 hours, although full benefit may take up to 1–2 weeks.
Does a steroid injection cure the problem permanently?
Steroid injections reduce inflammation and pain but may not permanently cure the underlying condition.
Can steroid injections stop working over time?
In some cases, repeated injections may become less effective, particularly if there is ongoing joint degeneration or chronic inflammation.
How many steroid injections can you have?
The number of injections depends on the area treated, the condition involved, and clinical guidance from your clinician.
Will walking affect how long the injection lasts?
Gentle walking will not reduce the effectiveness of the injection. Overloading the knee too soon, however, may shorten the duration of pain relief.
