For most individuals with frozen shoulder, one to three corticosteroid injections are considered appropriate during the course of treatment. The number of injections depends on several factors:
- Stage of frozen shoulder (freezing, frozen, or thawing)
- Response to previous injections
- Overall symptom severity and duration
- Presence of underlying conditions, such as diabetes, which may influence healing
Typically, if the first injection provides significant relief, additional injections may not be necessary. However, in cases where symptoms persist, a repeat injection may be given after a gap of 4 to 6 weeks.
Understanding Steroid Injections for Frozen Shoulder
Corticosteroid injections, also known as steroid injections, are commonly used to reduce inflammation and relieve pain in frozen shoulder. When delivered precisely into the shoulder joint capsule under ultrasound guidance, they can help improve mobility and comfort, especially in the early and painful stages of the condition.
Why Overuse Should Be Avoided
While corticosteroid injections are effective in reducing pain and inflammation, frequent or repeated use is not advisable. Excessive steroid exposure can lead to:
- Weakened soft tissues
- Joint cartilage damage
- Increased risk of infection
- Temporary increase in blood sugar, particularly in people with diabetes
Clinicians generally advise limiting corticosteroid injections to no more than three injections per joint within a 12-month period. This conservative approach ensures safety while maximising therapeutic benefit.
Ultrasound Guidance for Precision
At Alton Pain Clinic, our experienced clinicians use ultrasound-guided techniques to ensure the medication is accurately placed into the joint capsule. This level of precision:
- Enhances the effectiveness of each injection
- Reduces the risk of complications
- Minimises discomfort during the procedure
This approach allows us to optimise each dose, often reducing the need for multiple injections.
What to Expect After the Injection
Most patients experience improvement in symptoms within a few days. Some may have a flare-up of pain for 24–48 hours, which usually settles on its own. To aid recovery, it’s recommended to:
- Rest the shoulder for 24–48 hours post-injection
- Follow prescribed shoulder exercises
- Avoid heavy lifting or overhead activity temporarily
Your clinician will provide personalised aftercare instructions to support your outcome.
When Fewer Injections May Be Preferable
Certain conditions may require a more cautious approach, including:
- Diabetes
- Osteoporosis
- History of joint infection or immune suppression
Conclusion
While steroid injections for frozen shoulder can provide meaningful relief, they are not meant to be used indefinitely or in isolation. Most people benefit from one to three ultrasound-guided injections, spaced several weeks apart if needed. At Alton Pain Clinic, our team of experienced clinicians ensures that each injection is delivered precisely and only when appropriate, based on your individual needs and recovery progress.
Frequently Asked Questions
How effective are steroid injections for frozen shoulder?
Steroid injections can provide significant pain relief and improve shoulder mobility, especially during the early painful stage.
How quickly do steroid injections work for frozen shoulder?
Most patients notice improvement within a few days to two weeks, with reduced pain and increased comfort.
How long do the benefits last?
Pain relief can last several weeks to a few months, depending on the stage of frozen shoulder and individual response.
When is the best time to get a steroid injection?
The injections are most effective during the freezing (painful) stage, when inflammation is highest, helping to reduce pain and stiffness and accelerate recovery.
