What is frozen shoulder and how can it be treated? It is a condition that makes the shoulder painful and increasingly stiff; treatment usually combines guided movement, pain control, and time, with injections or procedures considered when needed.
The stiffness can make dressing, reaching overhead, and sleeping difficult. It often develops gradually, and recovery may take many months or longer.
This article explains the signs, likely causes, stages, and treatment choices. You’ll also find practical tips for exercising without aggravating the shoulder, plus advice on when to seek care and what other problems can look similar.
What is frozen shoulder and how can it be treated?
Frozen shoulder, also called adhesive capsulitis, is pain and stiffness caused by tightening and thickening of the capsule around the shoulder joint. The capsule is a flexible sleeve of tissue that helps hold the joint together. When it becomes inflamed and contracts, the shoulder has less room to move.
The main treatment is usually gradual, guided movement paired with strategies to manage pain. A clinician may also recommend medication or a corticosteroid injection. If severe stiffness continues despite appropriate nonsurgical care, a specialist may discuss a procedure to loosen the capsule.
Frozen shoulder limits both active movement (when you move your own arm) and passive movement (when someone else moves it for you). That pattern can help distinguish it from some other shoulder problems, though an examination is needed to confirm the cause.
What does frozen shoulder feel like?
Symptoms often begin gradually. At first, aching or sharp pain may be the main problem. Over time, stiffness can become more noticeable, and ordinary tasks may take more effort.
You may struggle to reach behind your back, put on a coat, fasten a bra, wash your hair, or lift an item onto a shelf. Pain can be worse at night, particularly when you lie on the affected side. Sleep disruption can add to fatigue and make pain harder to manage.
Movement is often restricted in several directions, especially when turning the arm outward or lifting it. The exact pattern varies. Some people have substantial pain; others mainly notice that their shoulder will not move as far as before.
Why does frozen shoulder happen?
In many cases, there is no clear cause. Frozen shoulder can develop without a known injury. It may also follow a period when the shoulder is kept still, such as after surgery, an injury, or another illness. Immobility does not guarantee frozen shoulder, but prolonged lack of movement can contribute to stiffness.
The condition is more common in middle age and is associated with diabetes and some thyroid conditions. Having one of these conditions does not mean you will develop frozen shoulder. It does mean it is useful to mention your medical history to a clinician, since it can affect assessment and care planning.
Other shoulder conditions can also cause pain and limited movement. Rotator cuff problems, arthritis, a fracture, and neck-related pain may need different treatment. Do not assume that every stiff or painful shoulder is frozen shoulder, especially if symptoms started after a significant injury.
What are the stages, and how long does recovery take?
Frozen shoulder is often described in three overlapping stages. These labels can help explain how symptoms change, but the stages do not have exact start and end dates. People do not always experience them in the same way.
- Freezing stage: Pain increases and movement gradually becomes more restricted. The shoulder may hurt at rest or at night.
- Frozen stage: Stiffness is prominent. Pain may ease for some people, but reaching and rotating the arm remain difficult.
- Thawing stage: Movement gradually returns. Improvement can be slow and uneven rather than a sudden release.
Recovery often takes many months and can take longer. Some people continue to have stiffness or discomfort after the most painful period has passed. The course is difficult to predict, so a treatment plan should be adjusted to your symptoms and progress rather than based on a fixed calendar.
How is frozen shoulder diagnosed?
A clinician will usually ask when the pain began, how it has changed, what movements are difficult, and whether an injury or period of immobility came first. They may ask about diabetes, thyroid conditions, past shoulder problems, and medicines you take.
During an examination, the clinician checks how far you can move the arm yourself and how far it can be moved gently with help. Restricted movement in both situations can support a frozen shoulder diagnosis. The examination also helps identify signs that point toward another cause.
Imaging is not always needed to diagnose frozen shoulder. An X-ray may be used to look for arthritis, a fracture, or another bone problem. Other tests may be considered if the history or examination suggests a different condition. Tell the clinician if pain began suddenly after an injury or if you have symptoms beyond the shoulder.
Which frozen shoulder treatments can help?
Treatment aims to reduce pain enough for you to keep the shoulder moving safely and gradually improve function. No single option suits everyone. The best plan depends on how painful and stiff the shoulder is, your health history, and how you respond over time.
| Option | What it may do | Best suited for |
|---|---|---|
| Activity changes and gentle movement | Maintains comfortable use without repeatedly provoking a flare | Most people as a foundation for care |
| Physical therapy | Provides tailored mobility work and guidance on safe progression | People who need help choosing and adjusting exercises |
| Pain medicines | May reduce discomfort enough to support sleep and movement | People whose symptoms limit daily activities, if medicines are safe for them |
| Corticosteroid injection | May reduce inflammation and pain, particularly earlier in the condition | Some people with substantial pain despite basic measures |
| Hydrodilatation | Uses fluid injected into the joint to stretch the capsule | Selected people with persistent restriction after discussion with a clinician |
| Manipulation or arthroscopic release | A specialist loosens the tight capsule under anesthesia or with keyhole surgery | Selected cases with lasting, disabling stiffness despite nonsurgical treatment |
Movement and physical therapy
Gentle range-of-motion exercises are often part of care. A physical therapist can show you how to move the shoulder in a way that matches its current sensitivity. The goal is gradual progress, not forcing the arm through pain.
During a very painful phase, aggressive stretching may worsen symptoms and make it harder to keep moving. As pain settles, a therapist may introduce longer or more challenging stretches and exercises. A home plan can help you practice consistently, but it should be changed if it repeatedly causes a lasting flare.
Pain relief and injections
A clinician or pharmacist can help you choose pain relief that fits your health history. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may ease pain for some people, but they are not safe for everyone. Stomach ulcers, kidney or heart conditions, blood thinners, pregnancy, and other medicines can affect whether an NSAID is appropriate. Follow product directions and ask a professional if you are unsure.
A corticosteroid injection places anti-inflammatory medicine into or near the shoulder joint. It may reduce pain, which can make movement and therapy more manageable. Its usefulness depends on the person and timing; it does not instantly remove all stiffness or guarantee a cure. Ask about likely benefits, risks, and whether an image-guided injection is appropriate.
Hydrodilatation, sometimes called distension arthrography, involves injecting fluid into the joint to stretch the capsule. It may be offered in selected cases, but the expected benefit and availability vary. A clinician can explain how it compares with continued therapy or an injection alone.
When might a procedure be considered?
If pain and major stiffness continue to interfere with daily life after a suitable course of nonsurgical care, an orthopedic specialist may discuss manipulation under anesthesia or arthroscopic capsular release. During manipulation, the shoulder is moved while you are anesthetized. In arthroscopic release, a surgeon uses small instruments to cut tight portions of the capsule.
These procedures are not the first step for most people. They carry risks, and rehabilitation afterward is important to maintain the movement gained. The decision should consider your overall health, the likely cause of the limitation, how much function is affected, and what nonsurgical options remain.
How to exercise a stiff shoulder safely at home
Use a gentle approach and follow any plan from your clinician or therapist. A helpful rule is that mild stretching discomfort may be tolerable, but sharp or escalating pain is a signal to ease off. If pain remains notably worse later or the next day, reduce the range, repetitions, or effort and ask for advice if the flare continues.
- Warm the area first. A warm shower or a comfortably warm pack may help you feel looser before movement. Avoid heat that could burn the skin, and do not use it where sensation is reduced.
- Choose a supported movement. For a pendulum, lean forward while supporting yourself with the other hand on a stable surface. Let the affected arm hang and make small, relaxed movements without forcing it.
- Use assistance rather than strength. A table slide can let your hand glide forward on a surface as you lean gently, helping the arm move without lifting it under its own power.
- Stay within a manageable range. Move slowly, breathe normally, and stop before sharp pain. A small comfortable movement done regularly is more useful than an intense stretch that triggers a flare.
- Track the response. Note which movements help and whether symptoms settle afterward. Share that information with your therapist so the plan can be adjusted.
Do not copy a demanding exercise routine from a video if it causes strong pain or does not account for your stage of symptoms. Exercise selection and dosage depend on the individual. If you are uncertain about a movement, ask a physical therapist to check your technique.
What can you do in daily life to protect movement?
Try to keep using the arm for comfortable tasks rather than holding it completely still. At the same time, avoid repeatedly testing the painful limit or forcing overhead movement. Small adjustments can make daily activity easier while preserving gentle use.
- Keep frequently used items at a comfortable height so you do not have to reach overhead.
- When dressing, put the affected arm into a sleeve first and take it out last, if that feels easier.
- Try sleeping on your back or the unaffected side, with a pillow supporting the sore arm.
- Break chores into shorter periods and change tasks if one position aggravates the shoulder.
- Ask a clinician how to keep the shoulder moving if another condition or procedure requires a sling or reduced activity.
A common mistake is to treat stiffness as a problem that must be stretched out forcefully. Because an irritated shoulder can react to excessive loading, harder stretching is not automatically better. Warm up first, use a comfortable range, and judge progress by how the shoulder responds afterward—not only by how far it moves during one session.
When should you seek medical care?
Arrange an assessment if shoulder pain or stiffness is worsening, disrupting sleep, limiting daily activities, or not improving. A clinician can check whether frozen shoulder is likely and rule out conditions that require different care. Early advice can also help you avoid exercises or activities that are poorly matched to your symptoms.
Seek urgent medical attention for severe pain after a fall or other injury, a visibly deformed shoulder, sudden inability to move the arm, or a hot, red shoulder accompanied by fever. Get emergency help if shoulder pain occurs with chest pressure, shortness of breath, faintness, sweating, or pain spreading to the jaw or arm, since these can signal a problem beyond the shoulder.
Frozen shoulder is a tightening of the tissue around the shoulder joint that causes pain and restricted movement. For many people, care starts with gentle, tailored movement and pain management; injections or procedures may be considered when symptoms remain difficult.
If you’re asking what is frozen shoulder and how can it be treated because your shoulder is limiting daily life, schedule an assessment with a healthcare professional. Until then, keep movement gentle, avoid forcing painful stretches, and seek urgent care for severe injury symptoms or chest-related warning signs.
