Frozen shoulder is a painful, stiff shoulder where the capsule around the joint thickens and shrinks. It usually takes one to three YEARS to settle.
You’ll often hear that it “gets better on its own.” Mostly true, not fully. Most people end up with a shoulder that works fine for daily life. But roughly 4 in 10 are left with some stiffness years later, and a small number keep real pain.
So waiting isn’t free. Early treatment, especially for the pain, is worth having.
The test that tells it apart
- Frozen shoulder is stiff both ways. You can’t lift or turn your arm, AND nobody else can move it for you either. There’s a hard block at the end, not just pain
- If someone else CAN move it through full range but it hurts when you do it yourself, it’s more likely a rotator cuff problem, not frozen shoulder
- Turning the arm outward goes first. Keep your elbow tucked at your side and turn your forearm out. In frozen shoulder this is usually the most limited movement
- X-rays look normal. They’re used to rule out arthritis, not to diagnose frozen shoulder
Symptoms
- Deep ache at the front and outside of the shoulder, sometimes down the upper arm
- Night pain, especially lying on that side
- Sharp catches of pain with sudden or unexpected movements
- Struggling to do up a bra, reach a back pocket, comb your hair or reach a high shelf
- Stiffness that slowly gets WORSE over the first few months, not better
The three stages
- Freezing: pain builds and movement starts to go. Roughly 2 to 9 months
- Frozen: pain eases, stiffness stays. Roughly 4 to 12 months
- Thawing: movement slowly returns. Months to two years
Treat these as a rough description, not a timetable.
Most people don’t feel themselves cross a line from one stage to the next. It’s more like pain early, stiffness later, and slow improvement that tails off.
Most frozen shoulders end up good enough. “Good enough” isn’t always the same as back to normal.
Who gets it
- About 2 to 5 in 100 people, mostly between 40 and 65, peaking in the mid-fifties
- Women slightly more than men
- Diabetes is the big one. People with diabetes are about five times more likely to get it. See frozen shoulder and diabetes
- Thyroid problems, both under and overactive
- After surgery, a fracture or time in a sling. Stiffness that follows an operation behaves differently and usually does better. See shoulder stiffness after surgery
How it usually ends
- Most people get back to a shoulder that does what they need, even if it doesn’t reach quite as high as the other one
- About 4 in 10 still have some measurable stiffness several years later. Most barely notice it
- About 6 in 100 are left with pain or stiffness that genuinely bothers them
- Worse at the start usually means slower to finish. Severe early pain and diabetes both predict a longer course
- The other shoulder: up to 1 in 5 people get it on the other side at some point. The same shoulder rarely freezes twice
What helps
- A steroid injection early, while pain is the main problem. It’s one of the best-supported treatments for this condition
- Exercises matched to how irritable the shoulder is. Gentle when it’s angry, firmer when it’s calm. See frozen shoulder exercises
- Keep using the arm within comfort for everyday tasks
- If progress stalls, there are procedures to consider. See frozen shoulder treatment
Things that can look like frozen shoulder
Arthritis of the shoulder, a dislocation that was never put back, infection, and rarely a tumor at the top of the lung can all show up as a painful, stiff shoulder. That’s why a proper examination matters before you settle on the diagnosis.
See a doctor soon if
- You have fever with a hot, swollen shoulder
- You have constant night pain and a history of cancer
- You have night sweats, weight loss or an unexplained lump
- You have numbness, tingling or weakness in the arm or hand
- The skin on the hand changes color, temperature or sweating
Get it checked if
- Pain and stiffness haven’t improved after 6 to 12 weeks
- Pain is getting worse or stopping you sleeping
- You’re not sure whether it’s frozen shoulder or something else
Treat the pain early. Match the stretching to the shoulder. Don’t assume it will fix itself completely.
