Beyond Cortisone: A New Look at Chronic Shoulder Pain

By a joint pain and radiology industry contributor.

You’ve done physical therapy. You’ve tried anti-inflammatory pills and maybe even had cortisone shots. But the deep ache in your shoulder won’t go away. It stops you from reaching, lifting, or sleeping well. This cycle of pain that comes and goes is a common problem for people with long-term conditions like frozen shoulder (also called adhesive capsulitis).

When these first treatments don’t work for long, the next step is often surgery. But now there is a different option. It targets the source of the pain without large cuts. These are called minimally invasive procedures. They use medical imaging to guide the treatment and are done by doctors called interventional radiologists. Finding a doctor with the right skills is important. People often start by searching for California Joint Pain Institute shoulder specialists or other experts who focus on these modern treatments.

This approach is not a replacement for all other treatments, but it is an important new option for certain types of long-lasting shoulder pain.

Quick answer: For long-lasting shoulder problems like frozen shoulder, a procedure called Shoulder Artery Embolization (SAE) offers a new option. It works by blocking the extra blood flow that causes swelling and pain. It can be an alternative when physical therapy and shots haven’t given you lasting relief.

Why Do Traditional Shoulder Treatments Sometimes Fail?

Common treatments sometimes fail because they only cover up the symptoms. They don’t fix the real cause of the long-term swelling and pain. In conditions like frozen shoulder, the problem is that too many tiny, new blood vessels have grown in the joint. These vessels keep feeding the pain. Shots can calm the swelling for a while, but they don’t stop the blood flow that makes it come back.

The main problem in many cases of long-term joint pain is the growth of new blood vessels. This is when a thick web of tiny blood vessels forms where it shouldn’t. These vessels carry cells that cause swelling right into the shoulder joint. This leads to pain, stiffness, and makes it hard to move. A cortisone shot can calm down the swelling that’s already there. But it doesn’t get rid of the network of blood vessels that will just bring more swelling back later. That’s why the relief from shots often doesn’t last.

Surgery can fix big problems like a major tear, but it takes a long time to recover. Even after a successful surgery, it can take a while to get back to normal. Additionally, a narrative review of rotator cuff tear management from Pmc notes that retearing after a primary repair occurs in approximately 20-94% of patients. For example, one study on rotator cuff surgery from the National Institutes of Health showed it often took six months for patients to move and use their shoulder much better. Full healing can take even longer; a prospective Pubmed study found that healing rates after arthroscopic repair increased from 64.3% at 1 year to 81.2% at 5 years. Because recovery takes so long, it’s a good idea to look at simpler options first, especially if the pain is from swelling and not a major tear.

❝ A big sign that your first treatments aren’t enough is how long the relief lasts. If a cortisone shot helps for only a few weeks before the pain comes back just as bad, you are likely treating a symptom, not the real cause of the pain.

The goal of newer, less invasive treatments is to break this pain cycle. Instead of just managing the swelling, they aim to cut off the extra blood supply that feeds it. This method gets to the root cause of the pain. It offers a chance for longer-lasting relief without open surgery.

How Do You Evaluate a Specialist for Shoulder Embolization?

The most important step is to make sure you see a board-certified interventional radiologist. This doctor should have special experience with a procedure called musculoskeletal embolization. This is a special field of medicine. It combines medical imaging (like X-rays) with procedures that use very small cuts. Orthopedic surgeons fix bones and joints with surgery. Interventional radiologists use imaging to guide tiny tubes, called catheters, through blood vessels to treat problems inside the body.

Knowing the difference between these doctors is key for a procedure like Shoulder Artery Embolization (SAE). You would see an orthopedic surgeon for a major injury, like a torn rotator cuff that needs to be surgically repaired, a procedure which can result in high long-term patient satisfaction rates between 85.7% and 100% according to a 2023 Pubmed systematic review. But for long-term pain caused by swelling and extra blood vessels, an interventional radiologist has the right training to work within the blood vessel system. The Society of Interventional Radiology has more information about what these doctors do.

Here is a simple breakdown of the different roles:

Feature	Orthopedic Surgeon	Interventional Radiologist
Primary Focus	Fixing the structure of bones, joints, and ligaments	Treating problems through blood vessels
Tools Used	Surgical tools like scalpels and scopes	Tiny tubes (catheters) and X-ray guidance
Typical Treatments	Joint replacement, fixing major tears	Embolization and other blood vessel procedures
Best For	Major tears, broken bones, unstable joints	Long-term pain from swelling, blood vessel problems

When you meet with a doctor, their training and experience are the best signs of quality. More doctors are starting to perform musculoskeletal embolization, but it is still a very specialized skill.

❝ Ask the doctor about their experience with embolization for joints and muscles (musculoskeletal). Many of these doctors do embolization for other problems in the body. Being an expert in those areas doesn’t mean they are an expert in the shoulder’s unique blood vessels.

To properly vet a specialist, ask these direct questions:

Are you a board-certified interventional radiologist with fellowship training? This confirms they have the highest level of training in this field.
How many Shoulder Artery Embolization procedures have you done? The number of procedures a doctor has done is a good sign of their experience. You want someone who does this procedure often.
How do you decide if I am a good candidate for this procedure? A good evaluation should include a physical exam, a look at your past treatments, and imaging tests like an MRI or ultrasound to check for signs of long-term swelling.
What are the usual results and risks for SAE in your practice? A good specialist should be able to clearly explain their success rates and any possible risks, even small ones.

What Actually Happens During a Shoulder Embolization?

The procedure is a very exact method done by an interventional radiologist. It usually happens in a special room, and you can go home the same day. The doctor blocks the tiny, extra arteries that cause the long-term swelling in your shoulder. This is all done through a tiny opening in your wrist or groin. The whole process is guided by live medical imaging.

First, the doctor numbs a small spot on your wrist. Then, they insert a very thin tube, called a catheter, into the artery. Using a type of live X-ray, they guide this catheter through your blood vessels up to your shoulder. You are awake for this, but you won’t feel the
