A cortisone injection in the shoulder typically provides pain relief for 6 weeks to 3 months, although some patients experience relief for several months. The duration depends on the underlying condition, severity of inflammation, and individual response to treatment.
A cortisone injection is commonly used to treat conditions such as shoulder impingement, bursitis, frozen shoulder and rotator cuff inflammation. It works by reducing inflammation within the joint or surrounding tissues, helping to relieve pain and improve movement.
At Alton Pain Clinic, we provide ultrasound-guided cortisone injections to ensure precise placement and optimal results.
How Long Does Pain Relief Usually Last?
Most patients experience relief for:
- 6 to 12 weeks on average
- Sometimes 3–6 months
- Occasionally shorter or longer depending on the condition
Some patients feel improvement within a few days, while for others it may take up to one week.
What Affects How Long It Lasts?
Several factors influence duration:
1. The Underlying Condition
Inflammatory conditions (such as bursitis) often respond very well. Structural problems may require additional treatment.
2. Severity of Inflammation
More severe inflammation may take longer to settle.
3. Activity Levels
Continuing aggravating activities may shorten the benefit.
4. Accuracy of Injection
Ultrasound guidance improves precision, which can enhance effectiveness and duration.
When Should You Consider an Injection?
You may benefit from a cortisone injection if:
- Shoulder pain has lasted more than a few weeks
- Sleep is disturbed
- Pain limits daily activities
- Conservative measures have not helped
Early intervention can prevent chronic pain patterns.
Key Takeaway
A shoulder cortisone injection typically lasts 6 weeks to 3 months, with some patients experiencing longer relief. Duration depends on the condition being treated and individual response.
If shoulder pain is affecting your sleep or daily activities, targeted treatment may help restore comfort and function.
