Patients with frozen shoulder often arrive in my office convinced they tore something. They didn’t fall or lift anything heavy. The shoulder started aching, the ache got worse at night, and then the arm stopped going where they asked it to. The right frozen shoulder treatment depends on which stage you are in. Doing the wrong thing at the wrong time can make the painful months harder than they need to be.
Key Takeaways
- Frozen shoulder moves through three overlapping stages: freezing, frozen, and thawing. Treatment should match the stage.
- In the painful freezing stage, calming inflammation matters more than aggressive stretching. A corticosteroid injection given early can meaningfully reduce pain.
- Stretching earns its place once pain settles and stiffness becomes the main problem.
- Many frozen shoulders improve without surgery, though the full course can take a year or longer. Procedures to release the capsule are an option for shoulders that stay stuck.
What Frozen Shoulder Is
The shoulder joint is wrapped in a capsule of connective tissue. In frozen shoulder, known medically as adhesive capsulitis, that capsule becomes inflamed, then thickens and tightens, and the pocket of the joint shrinks. The ball can no longer move freely in the socket.
The defining sign is lost motion in every direction, whether you try to move the arm yourself or someone else moves it for you. That passive stiffness is what separates frozen shoulder from a rotator cuff tear, where another person can usually lift the arm further than you can.
Frozen shoulder most often affects people between 40 and 60, and women more than men. Diabetes is the strongest known risk factor. Thyroid disease and a recent stretch of shoulder immobilization after an injury or surgery raise the risk as well. In many patients, no trigger is ever found, and I make a point of saying so, because people tend to search for something they did wrong.
Stage One, Freezing
The freezing stage can last anywhere from about six weeks to nine months. Pain is the main feature, and it is often worst at night. Motion slips away gradually, so reaching a back pocket or a high shelf gets harder week by week.
This is the stage where people most want to push through, and it is the stage where pushing backfires. Forcing an inflamed capsule to stretch can increase the pain and the inflammation behind it. Gentle motion within comfort keeps the shoulder moving without provoking it.
A useful tool here is a corticosteroid injection into the joint. The evidence for injections is strongest when they are given early, while inflammation is still driving the process. In my view, this is the stage where an injection earns its place, and waiting months to offer one wastes its best window. Sleep positioning, with a pillow supporting the arm, and short courses of anti-inflammatory medication may help too.
Stage Two, Frozen
The frozen stage lasts roughly four to six months. Pain eases for the majority, while stiffness reaches its worst. Fastening a seatbelt, tucking in a shirt, or washing the back of your hair can become real obstacles.
Now, stretching becomes useful. A physical therapist can guide a program of gentle, sustained stretches that you repeat daily, and I care more about consistency than intensity. Short, frequent sessions tend to beat one hard session a week. Injections still help some patients with lingering pain in this stage, though they do less for motion.
Stage Three, Thawing
Over the thawing stage, which can run from six months to two years, motion comes back gradually. Continued stretching helps the shoulder recover as much range as possible. The majority regain the bulk of their function. Some keep a mild loss of rotation that they rarely notice in daily life.
When a Frozen Shoulder Won’t Thaw
A smaller group of shoulders stay stiff and limiting despite months of well-run nonsurgical care. For those patients, I discuss three options. Hydrodilatation injects a volume of fluid into the joint to stretch the capsule from the inside, and the evidence for it is mixed. Manipulation under anesthesia moves the shoulder through its range while the patient is asleep. An arthroscopic capsular release uses small instruments to cut the tightened capsule directly.
A large, randomized study that ran at 35 hospitals in the United Kingdom compared three treatments in 503 adults with frozen shoulder: early structured physical therapy combined with a steroid injection, manipulation under anesthesia, and arthroscopic capsular release. Patients in all three groups improved considerably. For me, that supports giving well-run nonsurgical care a real chance first and saving a procedure for the shoulder that stays stuck.
What I See in My Patients
Diabetes changes the course more than any other factor I see. Frozen shoulder in patients with diabetes can be more stubborn, and it can affect both shoulders. I also warn these patients that a steroid injection can raise blood sugar for a few days, and I ask them to watch their readings closely afterward.
Misdiagnosis is common. A lot of the frozen shoulders I see in Renton and Maple Valley spent months being treated as impingement or a cuff problem, sometimes with aggressive therapy that made the pain worse. One quick test sorts most of them out: with the elbow at your side, can the arm rotate outward? In frozen shoulder, that motion is lost early, even when someone else tries to move it.
Because my training includes a hand surgery fellowship, I also watch for frozen shoulder after wrist and hand injuries. An arm that spends weeks in a cast and sling can let the shoulder quietly stiffen, and the shoulder deserves attention during that recovery, not after it.
My Approach to Frozen Shoulder Treatment
I start by confirming the diagnosis. An exam and X-rays are usually enough. X-rays rule out shoulder arthritis, which also causes stiffness and becomes more likely after 60. MRI is rarely necessary unless something in the exam suggests another problem. I go through the images with you during the visit, so you can see why the joint is stiff.
Then I stage it. If you are in the painful freezing stage, I will talk with you about an injection and a gentle home motion program. If stiffness is the main problem, therapy shifts toward stretching.
I set expectations in months, not weeks. Frozen shoulder treatment rewards patience, and patients who understand the timeline from the first visit handle it better. I only raise a procedure after a genuine trial of nonsurgical care.
Summary
Frozen shoulder passes through three stages, and each one calls for something different. In the freezing stage, the goal is calming pain, and an early injection can be one of the most useful tools. In the frozen stage, consistent stretching protects your motion. In the thawing stage, motion returns gradually. Surgery is reserved for shoulders that stay stuck after a real effort without it.
If your shoulder has stiffened over weeks, it aches at night, and you can no longer reach a back pocket or an overhead shelf, get it examined early. That is when treatment does the most good. Request an appointment at my Renton or Maple Valley office, and we will work out which stage you are in and what fits it.
Frequently Asked Questions
How long does frozen shoulder last?
It varies widely. Taken together, the three stages commonly span one to three years. Treatment in the freezing stage can ease the pain, and the large majority of shoulders regain much of their motion over time.
Should I stretch a frozen shoulder?
It depends on the stage. During the painful freezing stage, gentle motion within comfort is better than forceful stretching. Once pain settles and stiffness is the main problem, a daily stretching program becomes an important part of recovery.
Does a cortisone shot help frozen shoulder?
An injection into the joint can meaningfully reduce pain, especially when given early in the freezing stage. It does less for motion later on. If you have diabetes, expect that it may raise your blood sugar for a few days.
When is surgery needed for frozen shoulder?
Only when significant stiffness persists despite months of consistent nonsurgical treatment. Options include manipulation under anesthesia and arthroscopic capsular release, and outcomes are broadly similar to well-run nonsurgical care at one year.
