Overview
The shoulder joint is wrapped in a thin, loose capsule that normally has enough slack to let the arm reach overhead and behind the back. In adhesive capsulitis that capsule becomes inflamed, then thickens and contracts, and the shoulder loses motion in every direction. The capsule eventually loosens again, but “eventually” can mean two years or more, and the shoulder that is left is not always a full recovery.
What decides treatment is which stage the shoulder is in. In the early painful stage the problem is inflammation, and an injection into the joint does more than any exercise. In the stiff stage the problem is contracture, and stretching is the treatment. A shoulder still tightly frozen after six months of proper treatment is the one considered for release. Getting the stage right matters, because stretching an inflamed capsule aggressively makes it worse.
Common Symptoms
- Deep, aching shoulder pain that started without a clear injury and steadily worsened over weeks
- Night pain, particularly rolling onto the shoulder, which disturbs sleep for months
- Progressive loss of motion: difficulty fastening a bra, reaching a back pocket, washing hair, or reaching into the back seat of a car
- Stiffness that is the same whether the patient moves the arm or someone else moves it for them
The defining feature is loss of passive motion: the shoulder will not go there even when relaxed. A shoulder that hurts overhead but can be moved fully by the examiner is more likely impingement or bursitis. A stiff shoulder with grinding in a patient over 60 may be arthritis, which looks identical on exam and is separated by the X-ray. Weakness rather than stiffness points to a rotator cuff tear.
Causes & Risk Factors
Most cases are idiopathic. The condition is most common between 40 and 60 and affects women more than men. Diabetes is the strongest risk factor: people with diabetes are several times more likely to develop frozen shoulder, tend to have both shoulders affected over time, and are harder to treat. Thyroid disease, Dupuytren's contracture, and a period of immobilization after any shoulder injury or surgery also raise the risk, which is why Dr. O'Donnell starts passive motion early after every shoulder operation. It is rare under 40 without one of these factors, so a stiff shoulder in a 25-year-old is examined for another cause.
How It Is Diagnosed
Frozen shoulder is a clinical diagnosis. Dr. O'Donnell measures active and passive motion in forward elevation, external rotation with the elbow at the side, and internal rotation behind the back, and compares each with the other shoulder. The defining finding is loss of passive external rotation at the side, usually to less than half the normal side, together with restriction in at least one other direction. Cuff strength is normal apart from pain.
X-rays are taken at the first visit because glenohumeral arthritis mimics frozen shoulder exactly on exam, and the X-ray tells them apart: in frozen shoulder the joint is normal. MRI is ordered only when something does not fit, such as weakness, a history of injury, or a shoulder that fails to improve as expected. Ultrasound is used to guide injections.

Treatment Options
Non-operative care
Nearly every frozen shoulder is treated without surgery, and the goal is to shorten a course that would otherwise run one to three years. In the painful freezing stage, Dr. O'Donnell places a corticosteroid injection into the glenohumeral joint under ultrasound guidance. Given early, it reduces pain and night waking within days and appears to shorten the inflammatory phase; a second injection can be given if the first wears off before the stiffness has begun to improve. Hydrodilatation, in which the joint is distended with a larger volume of saline and steroid to stretch the capsule from inside, is an option for shoulders that are already stiff. Throughout, a daily home stretching program in four directions, guided by physical therapy, is what restores motion; stretches are held at the point of tension, not pushed through pain. Most patients regain functional motion within six to nine months of starting treatment.
Manipulation and arthroscopic capsular release
A shoulder still tightly restricted after at least six months of injection and structured stretching, or a patient who cannot wait that long, is considered for release. Under a nerve block and general anesthesia, Dr. O'Donnell divides the thickened capsule arthroscopically and then gently manipulates the shoulder through its full range, which is more controlled than manipulation alone and avoids fracturing bone in older or diabetic patients. Motion gained in the operating room is kept only with therapy starting the next day, because the capsule will re-tighten if allowed to. The procedure is performed as an outpatient at Bayside Surgery Center.
Recovery & What to Expect
Untreated, frozen shoulder moves through three overlapping stages. Treatment does not skip them, but it shortens the painful one and makes clear when to stretch.
| Stage | Typical timing | What happens |
|---|---|---|
| Freezing | Months 0–6 | Pain dominates, worst at night and at end-range; motion is lost progressively. Injection and gentle motion within comfort; no aggressive stretching. |
| Frozen | Months 4–12 | Pain eases but the shoulder is stiff in all directions. Daily four-direction stretching, physical therapy, hydrodilatation if progress stalls. |
| Thawing | Months 6–24 | Motion returns gradually. Stretching continues; strengthening added as motion allows. Release considered if still tightly restricted 6 months or more into treatment. |
| After capsular release | Days to 12 weeks | Therapy begins the day after surgery to hold the motion gained; sling for comfort only for a few days. Strengthening from about week 6; full activity around 3 months. |
Desk work is rarely interrupted at any stage. Driving is possible once the arm can reach the wheel without sharp pain, which after a release is usually within a week. Overhead sport such as tennis, swimming and golf returns when motion is close to full, which non-operatively may take most of a year and after release is typically two to three months.
Frequently Asked Questions
Can frozen shoulder heal on its own?
Yes, in most cases, but slowly. Left alone it runs through freezing, frozen and thawing stages over one to three years, and some patients are left with permanent loss of motion, particularly in diabetes. Treatment does not change the biology, but an early injection shortens the painful stage and a structured stretching program gets more motion back sooner.
What is the fastest way to get rid of frozen shoulder?
An ultrasound-guided corticosteroid injection into the joint in the first few months, followed immediately by a daily stretching program. The injection settles the pain within days so the stretching can be done properly; waiting for the pain to pass on its own adds months. Arthroscopic release is the fastest route for a shoulder still tightly frozen after 6 months of that.
Should I push through the pain when stretching a frozen shoulder?
Stretch to the point of firm tension and hold; do not force through sharp pain. In the early inflamed stage, aggressive stretching increases inflammation and can make the capsule tighter. Once the pain has settled and the shoulder is simply stiff, stretching can be more forceful, several times a day, and that is when motion comes back.
Is frozen shoulder related to diabetes?
Strongly. Frozen shoulder is several times more common in people with diabetes, tends to be more severe, more likely to affect both shoulders, and slower to resolve. Dr. O'Donnell checks blood sugar in patients presenting with frozen shoulder who have not been tested, because unrecognized diabetes is found this way with some regularity.
When is surgery needed for frozen shoulder?
When the shoulder is still tightly restricted after at least 6 months of injection and structured stretching, or when the stiffness is preventing work or sport and the patient cannot wait out a two-year course. Arthroscopic capsular release with manipulation is an outpatient procedure; the motion regained is kept only with therapy starting the next day.
