Yes — cortisone injections can significantly reduce pain and inflammation caused by calcific tendonitis, especially during acute flare-ups.
An ultrasound-guided cortisone injection targets inflammation around the calcium deposit and subacromial bursa, often providing relief within a few days. While it does not dissolve the calcium deposit itself, it can dramatically reduce symptoms and improve mobility.
What Is Calcific Tendonitis?
Calcific tendonitis of the shoulder occurs when calcium crystals accumulate in the rotator cuff tendon, most commonly the supraspinatus tendon. This can trigger:
- Sudden severe shoulder pain
- Difficulty lifting the arm
- Pain when lying on the affected side
- Sharp pain with overhead movement
The condition often goes through phases, and symptoms can become intense when the body starts breaking down the calcium deposit.
How Do Cortisone Injections Help?
A cortisone injection for calcific tendonitis works by:
- Reducing inflammation around the calcium deposit
- Settling irritation in the subacromial bursa
- Relieving swelling and pressure
- Improving range of motion
At Alton Pain Clinic, we use ultrasound-guided cortisone injections, which ensure:
- Accurate placement of medication
- Reduced risk of complications
- Better clinical outcomes
- Targeted treatment directly into the inflamed area
Ultrasound guidance is particularly important in calcific tendonitis because inflammation can involve multiple structures around the rotator cuff.
How Quickly Does It Work?
Most patients notice improvement within:
- 3–7 days after the injection
- Maximum benefit often within 2 weeks
Pain relief may last:
- Several weeks
- Several months
- Long enough for the inflammatory phase to settle
Does Cortisone Remove the Calcium Deposit?
No — a cortisone shot does not dissolve the calcium deposit itself.
However, it reduces the inflammation caused by the deposit. In many cases, the body gradually reabsorbs the calcium naturally over time once inflammation settles.
In more persistent cases, additional treatments may be considered.
Who Is a Good Candidate?
You may benefit from an ultrasound-guided cortisone injection for calcific tendonitis if you have:
- Severe shoulder pain
- Night pain affecting sleep
- Limited shoulder movement
- A confirmed calcium deposit on imaging
- Ongoing inflammation despite conservative care
Why Choose Ultrasound-Guided Injections?
Research shows blind (non-guided) injections are less accurate.
At Alton Pain Clinic, we specialise in:
- Ultrasound-guided shoulder injections
- Targeted subacromial bursa injections
- Precise cortisone placement
- Minimally invasive pain management
This approach improves safety, accuracy, and clinical effectiveness.
Key Takeaway
Cortisone injections are highly effective for reducing inflammation and pain caused by calcific tendonitis, particularly when delivered using ultrasound guidance.
While the injection does not remove the calcium deposit, it can provide significant relief and improve shoulder mobility — often avoiding the need for surgery.
Frequently Asked Questions
How effective are cortisone injections for calcific tendonitis?
They are very effective at reducing inflammation and pain, especially during acute flare-ups.
How long does relief last?
Relief can last from several weeks to several months, depending on the severity of inflammation.
Are ultrasound-guided injections better?
Yes. Ultrasound guidance improves accuracy and ensures medication is delivered precisely to the inflamed area.
Is the injection painful?
Most patients experience only mild discomfort during the procedure.
Can calcific tendonitis heal on its own?
In many cases, the body eventually reabsorbs the calcium deposit, but treatment helps manage severe symptoms during this process.
