Shoulder Stuck? Why Your Joint Is Frozen & Medically Approved Next Steps

If your shoulder feels stiff, painful, and increasingly hard to move, you may be dealing with frozen shoulder — also known as adhesive capsulitis. This condition can make simple daily tasks like getting dressed, reaching overhead, or fastening a seatbelt frustrating and painful.

The good news? Frozen shoulder is treatable. The not‑so‑good news? It often takes time and the right approach to recover fully.

Here's what's really happening inside your joint — and what medically approved next steps can help you safely regain movement.

What Is Frozen Shoulder?

Frozen shoulder (adhesive capsulitis) is a condition where the shoulder joint becomes stiff, inflamed, and painful due to thickening and tightening of the joint capsule.

The shoulder is a ball‑and‑socket joint surrounded by connective tissue called the capsule. In frozen shoulder:

• The capsule becomes inflamed
• It thickens and tightens
• Scar‑like tissue (adhesions) may form
• Synovial fluid decreases

The result? Restricted movement and significant stiffness.

Why Does Frozen Shoulder Happen?

In many cases, there's no single clear cause. However, certain risk factors increase your chances:

Common Risk Factors

• Age 40–60 (most common group)
• Diabetes (strongly associated)
• Thyroid disorders
• Heart disease
• Parkinson's disease
• Prolonged shoulder immobility (after surgery, fracture, or injury)
• Previous shoulder injury

If your shoulder hasn't been moving normally for weeks or months, that lack of motion alone can trigger frozen shoulder.

The Three Stages of Frozen Shoulder

Frozen shoulder typically progresses in three stages. Understanding this helps set realistic expectations.

1. Freezing Stage (Painful Phase)

• Increasing shoulder pain
• Pain worse at night
• Gradual loss of motion
• Can last 6 weeks to 9 months

2. Frozen Stage (Stiff Phase)

• Pain may decrease
• Stiffness becomes severe
• Shoulder feels "stuck"
• Daily tasks are difficult
• Can last 4–12 months

3. Thawing Stage (Recovery Phase)

• Motion slowly improves
• Less discomfort
• Can last 6 months to 2 years

Yes — full recovery can take time. But most people eventually regain most or all function with appropriate treatment.

Symptoms That Suggest Frozen Shoulder

Common symptoms include:

• Dull, aching shoulder pain
• Pain radiating into the upper arm
• Significant stiffness
• Trouble reaching overhead or behind your back
• Difficulty sleeping on the affected side
• Gradual loss of both active and passive range of motion

One key feature: both you and your doctor cannot move the shoulder fully — even when the arm is relaxed.

When It Might Be Something More Serious

While frozen shoulder is common and usually not dangerous, some shoulder pain can signal other problems.

Seek urgent medical care if you have:

• Chest pain or pressure
• Shortness of breath
• Sweating or nausea with shoulder pain
• Sudden severe injury
• Fever with redness and swelling
• Significant weakness after trauma

These could signal heart issues, infection, or major injury. Always speak to a doctor immediately if symptoms could be life‑threatening.

How Doctors Diagnose Frozen Shoulder

Diagnosis is typically clinical, meaning based on:

• Medical history
• Physical exam
• Testing range of motion

Your doctor may order imaging (like X‑rays or MRI) to rule out:

• Arthritis
• Rotator cuff tears
• Fractures
• Tumors (rare)

There's no single blood test that confirms frozen shoulder, but your doctor may screen for diabetes or thyroid issues.

---

Medically Approved Next Steps

Treatment depends on the stage of frozen shoulder and symptom severity.

1. Pain Management

Controlling pain allows better participation in physical therapy.

Common options:

• NSAIDs (like ibuprofen or naproxen)
• Acetaminophen
• Short‑term prescription anti‑inflammatory medications
• Corticosteroid injections (especially helpful early)

Steroid injections can significantly reduce inflammation during the freezing stage and may shorten recovery time.

---

2. Physical Therapy

Physical therapy is the cornerstone of treatment.

A trained therapist will guide:

• Gentle stretching exercises
• Range‑of‑motion work
• Gradual strengthening

Important:
Aggressive therapy too early can worsen pain. Treatment should match your stage of frozen shoulder.

Home exercises are often prescribed and should be done consistently — but without pushing into severe pain.

---

3. Hydrodilatation (Capsular Distension)

In some cases, doctors inject sterile fluid into the joint capsule to stretch it.

This can:

• Improve range of motion
• Reduce stiffness
• Provide faster symptom relief

It's typically done under imaging guidance.

---

4. Manipulation Under Anesthesia

If conservative treatment fails, your doctor may recommend:

• Manipulation under anesthesia (the shoulder is gently moved while you're asleep)
• Arthroscopic capsular release (minimally invasive surgery)

These are usually reserved for severe, persistent cases that don't improve after several months of therapy.

Most people do not need surgery.

What You Can Do at Home

While medical care is important, self‑care plays a big role.

Helpful Habits

• Keep the shoulder gently moving daily
• Use heat before stretching
• Apply ice after exercises if inflamed
• Maintain good posture
• Sleep with pillow support under the arm

What to Avoid

• Forcing painful movements
• Ignoring worsening stiffness
• Complete immobilization
• Heavy lifting during painful stages

Movement — within reason — is critical.

---

How Long Does Frozen Shoulder Last?

Recovery varies. On average:

• Mild cases: 12–18 months
• More severe cases: Up to 2–3 years

That sounds long — but remember:

• Pain often improves before stiffness resolves
• Most people recover functional motion
• Permanent severe disability is uncommon

Early treatment may shorten the course.

---

Frozen Shoulder and Diabetes

If you have diabetes, you're significantly more likely to develop frozen shoulder — and it may be more severe.

If diagnosed:

• Monitor blood sugar closely
• Work closely with your healthcare provider
• Address metabolic control

Managing underlying conditions improves recovery outcomes.

---

Can Frozen Shoulder Come Back?

Recurrence in the same shoulder is uncommon, but possible. Some people develop it in the opposite shoulder later.

Maintaining shoulder mobility and managing underlying health conditions reduces risk.

---

When to Speak to a Doctor

You should speak to a doctor if:

• Shoulder stiffness lasts more than a few weeks
• Pain interferes with sleep
• You cannot lift your arm normally
• Symptoms worsen despite home care
• You have underlying diabetes or thyroid disease
• There are signs of infection or trauma

While frozen shoulder is not usually dangerous, untreated stiffness can lead to prolonged disability.

If symptoms could represent something more serious — especially chest pain, breathing difficulty, or sudden severe weakness — seek immediate medical attention.

The Bottom Line

Frozen shoulder is frustrating, painful, and slow to heal — but it is treatable.

The key facts:

• It happens when the shoulder capsule tightens and thickens
• It progresses in predictable stages
• Early treatment can reduce severity
• Physical therapy is essential
• Most people recover over time

If you're experiencing shoulder stiffness and pain but aren't sure if it's frozen shoulder, take a few minutes to complete a free Adhesive Capsulitis symptom assessment to help identify what might be causing your symptoms.

Then take the most important next step: speak to a doctor.

Getting a clear diagnosis and a stage‑appropriate treatment plan can shorten recovery, reduce pain, and help you safely regain full shoulder movement.
