Frozen shoulder (adhesive capsulitis)

How frozen shoulder develops

Frozen shoulder typically develops gradually, starting with inflammation in the shoulder capsule and progressing to thickening and contraction of the surrounding tissue.

Inflammation and tightening of the shoulder capsule

As swelling persists inside the joint, fibrotic tissue forms and the capsule stiffens. This tightening limits how far you can raise, rotate, or reach with your arm.

Adhesive capsulitis vs. other shoulder conditions

Unlike rotator cuff tears or bursitis, adhesive capsulitis affects the capsule, not the muscles or tendons. It usually develops slowly without a major injury and continues to worsen unless treated.

How frozen shoulder impacts daily life

A frozen shoulder makes everyday activities, such as dressing, reaching overhead, driving, or lifting objects, increasingly difficult. Pain may be constant or triggered by certain movements, and stiffness often limits both strength and flexibility.

Common symptoms and movement limitations

People with a frozen shoulder often struggle with lifting their arm, reaching behind their back, or performing simple rotational movements. Many also experience a deep, aching pain that radiates into the upper arm.

When shoulder pain starts to affect sleep and function

Nighttime pain is one of the most common and frustrating symptoms of frozen shoulder. Lying on the affected side may be unbearable, and repeated sleep disruptions can impact daytime energy and overall quality of life.

What causes frozen shoulder?

Frozen shoulder occurs when inflammation triggers the thickening and contraction of the shoulder capsule, resulting in a reduction of joint mobility over time.

The role of inflammation and scar tissue

Inflamed tissue can gradually turn into dense scar tissue, further tightening the capsule. As this process continues, it becomes harder to move the shoulder without pain.

Common risk factors

Several factors increase the likelihood of developing frozen shoulder, including:

• Age between 40 and 60
• Diabetes or thyroid disease
• Shoulder immobilization after injury or surgery
• Autoimmune or hormonal conditions
• Inactivity or limited shoulder movement

Stages of frozen shoulder

A frozen shoulder progresses through three predictable phases, each affecting movement and pain in distinct ways.

1. Freezing stage

Pain gradually increases, and shoulder motion becomes restricted. Symptoms often worsen over several months.

2. Frozen stage

Pain may improve, but stiffness becomes severe. Lifting, rotating, or reaching becomes significantly limited.

3. Thawing stage

The shoulder slowly regains mobility as the capsule loosens. Complete recovery may take months.

How is frozen shoulder diagnosed?

Diagnosis begins with a review of your symptoms, medical history, and physical exam to assess the range of motion and pain patterns.

Physical exam and medical history

One of our expert providers will measure active and passive movement, evaluate stiffness, and determine whether symptoms align with adhesive capsulitis.

Imaging to confirm diagnosis

X-rays, ultrasound, or MRI may be performed to rule out other causes, such as arthritis or tendon tears, and confirm thickening of the capsule.

When to seek treatment at Georgia Endovascular

If symptoms persist or worsen, early treatment helps prevent long-term stiffness and improves comfort.

Why early intervention matters

Frozen shoulder can last for years without treatment. Early evaluation can shorten recovery time and reduce the risk of permanent motion loss.

Signs that conservative therapies may not be enough

Advanced, minimally invasive care may be needed if you:

• Have persistent stiffness for 3+ months
• Experience severe night pain
• See little improvement with physical therapy or injections
• Have difficulty performing daily tasks

Adhesive capsulitis embolization (ACE)

Georgia Endovascular offers adhesive capsulitis embolization, a minimally invasive treatment that reduces inflammation in the shoulder capsule and restores mobility without the need for surgery.

What ACE is and how it works

ACE utilizes advanced imaging to target abnormal blood vessels that contribute to shoulder inflammation. By reducing this excess blood flow, the procedure helps decrease pain and improve the range of motion.

A step-by-step overview of the procedure

1. A small catheter is inserted into an artery in the wrist or groin.
2. Using real-time imaging, the catheter is guided to tiny arteries surrounding the shoulder capsule.
3. Microscopic particles are released to reduce abnormal blood flow and inflammation.
4. Over time, pain decreases and flexibility gradually returns.

Recovery timeline and patient expectations

Most patients go home the same day as their ACE procedure and return to light activities within a few days. Improvement builds over several weeks, with continued progress for months.

Benefits of ACE compared to traditional surgery

ACE provides significant relief from frozen shoulder symptoms while avoiding the risks, recovery time, and discomfort associated with surgical procedures. 

In fact, clinical evidence published in the National Library of Medicine shows that ACE delivers substantial improvements in pain and mobility, with high rates of procedural success and a strong safety profile.

Here are some other ACE benefits:

• An outpatient procedure with minimal downtime: ACE uses a tiny entry point and requires no stitches, large incisions, or hospital stay.
• Less pain, faster relief, and no surgical scars: Because the procedure avoids cutting tissue, most patients experience less discomfort and return to normal routines sooner.
• Lower risk than manipulation or surgical release: ACE reduces inflammation without the potential complications that can occur with manipulation under anesthesia or arthroscopic surgery.

Is ACE right for you?

ACE can be an effective, nonsurgical solution for individuals who have not found relief through conservative care.

Ideal candidates for adhesive capsulitis embolization

ACE may be appropriate if you:

• Have confirmed frozen shoulder
• Experience persistent stiffness and pain
• Have tried therapy, injections, or medication without progress
• Prefer a minimally invasive alternative to surgery

If movement remains limited or pain disrupts daily life, ACE may provide longer-lasting improvement than traditional nonsurgical therapies.

FAQs about frozen shoulder

It’s normal to have questions when shoulder pain disrupts your daily life. These answers can help you better understand frozen shoulder and your treatment options with Georgia Endovascular.

Can frozen shoulder go away on its own?

Yes, but the process is slow and may take 1–3 years to complete. Many people seek treatment to accelerate recovery.

How long does frozen shoulder last?

Most cases of frozen shoulder last 12–36 months, depending on the severity and type of treatment.

What makes ACE different from other treatments?

ACE addresses abnormal blood flow and inflammation directly, offering longer-lasting relief than injections or physical therapy alone.

Is the procedure painful?

Most patients experience only mild pressure during ACE, and soreness afterward is typically minimal.

How soon can I return to daily activities after ACE?

Light activity is usually possible within a few days, with continued improvement over time.
