A frozen shoulder tends to announce itself in small ways at first. In my Largo and Palm Harbor clinics, it is the golfer who can no longer finish a backswing, or the patient who has started reaching for the seatbelt with the wrong hand because the right one won’t go back that far. By the time they reach my office, they have been living with it for months. Treatment for frozen shoulder pain rarely starts in the operating room, and many of my patients get their motion back without surgery.
Key Takeaways
- Frozen shoulder happens when the capsule around the joint thickens and tightens, limiting motion in every direction.
- It moves through a painful phase, a stiff phase, and a recovery phase, and the right treatment depends on which phase you are in.
- Physical therapy, pain control, and a cortisone injection are where I start, and that combination gets most patients through it.
What Frozen Shoulder Actually Is
Your shoulder joint sits inside a capsule, a sleeve of connective tissue that wraps around the ball and socket. In a frozen shoulder, also called adhesive capsulitis, that capsule becomes inflamed, then thickens and contracts. The joint has less room to move, so the arm gets stuck in every direction at once.
Nobody fully understands why it starts. It can follow a minor injury or a stretch of time with the arm held still. Plenty of cases have no clear trigger at all. It shows up mainly between the ages of 40 and 60, more in women than men, and people with diabetes or thyroid conditions are at higher risk.
The Three Stages, and Why They Matter for Treatment
Frozen shoulder follows a fairly predictable course:
- Freezing. Pain builds gradually and is commonly worst at night. Motion starts slipping away. Pain is the main problem here.
- Frozen. The pain eases somewhat, but stiffness peaks. Getting dressed, reaching a high shelf, and fastening a seatbelt all become chores.
- Thawing. Motion slowly returns, sometimes over many months.
Left untreated, the full cycle frequently lasts one to three years, though the timeline varies widely from person to person.
Matching the treatment to the stage matters more than any single treatment. Stretching hard during the freezing stage can make an inflamed capsule angrier, not looser. The same stretching in the frozen stage might be exactly what the shoulder needs.
How I Tell Frozen Shoulder Apart from a Rotator Cuff Tear
Many of the frozen shoulders I see arrive with an MRI already ordered for a suspected rotator cuff tear. The two conditions feel alike: pain on the outside of the arm, trouble reaching overhead, bad nights.
A hands-on exam generally separates them within a few minutes. With a rotator cuff tear, the arm may be weak, but I can still lift it for you. With a frozen shoulder, the arm is stuck no matter who moves it. Turning the forearm outward with the elbow at your side is typically the first motion to go and the most telling one.
X-rays matter too. In a frozen shoulder they look normal, which helps rule out arthritis, another common source of a stiff, painful shoulder.
Treatment for Frozen Shoulder Pain: Where I Start
My approach to frozen shoulder is conservative, and I mean that in the most active sense of the word. Waiting it out is a legitimate option, but I just don’t think anyone should have to sleep badly for a year while the capsule sorts itself out.
For a shoulder in the painful freezing stage, a cortisone injection into the joint is a helpful tool. It calms the inflamed capsule, and many patients sleep better afterward. It also opens a window where therapy becomes tolerable. I’m clear with people that the injection treats pain, not stiffness. On its own, it won’t give the motion back.
Physical therapy is the backbone of treatment. Early on, the goal is gentle motion that stays inside a tolerable range: pendulum swings, assisted reaching, short stretches done several times a day. Once the pain settles, the stretching gets firmer. A good therapist adjusts to the stage.
A few other pieces help. Heat before stretching loosens the shoulder. Over-the-counter anti-inflammatories, used as directed and for limited stretches of time, might take the edge off the worst nights. If you have diabetes, good blood sugar control matters for this condition too. And when frozen shoulder shows up in someone who has never been screened for diabetes, I suggest a conversation with their primary care doctor.
When the Shoulder Won’t Let Go
A small group of patients stay stiff after several months of consistent therapy and an injection. For those shoulders, a few procedures exist to stretch or release the tight capsule:
- Hydrodilatation. The joint is filled with sterile fluid, usually alongside a steroid, to stretch the capsule from the inside.
- Manipulation under anesthesia. While the patient is asleep, the shoulder is moved through its range to stretch the contracted tissue.
- Arthroscopic capsular release. The tightest portions of the capsule are released through small incisions using a camera.
A frozen shoulder trial in the United Kingdom compared manipulation, capsular release, and structured physical therapy paired with a steroid injection. All three groups improved substantially at one year, and none came out clearly ahead. The surgical release carried more complications. That matches my own bias: a procedure is a tool for the stubborn shoulder, not a shortcut. It’s why I start with conservative treatment for most patients with frozen shoulder.
What I See in My Patients
Tampa Bay is an active place, and frozen shoulder hits people in the middle of active lives. A typical patient of mine is in their fifties, playing pickleball three mornings a week or golfing on the weekends. The loss of overhead reach is what finally brings them in.
The pattern I see over and over is the patient who pushed through the painful early months with aggressive stretching, convinced they could out-work it. As a sports medicine surgeon, I understand that instinct, and athletes bring it to me every week. But frozen shoulder is one of the few shoulder problems where working harder early backfires. The capsule is inflamed, and forcing it keeps it inflamed.
Summary
Frozen shoulder is a tightening of the joint capsule that moves through painful, stiff, and recovery stages. Treatment for frozen shoulder pain works best when it matches the stage: pain control and a cortisone injection early, steady therapy throughout, and a procedure only for the shoulder that stays stuck. Surgery is rarely needed, though the process takes patience.
If your shoulder has been getting stiffer for more than a few weeks, especially if you can’t turn your arm outward or reach behind your back, I’d like to examine it. You can schedule an evaluation at my Largo, St. Petersburg, Palm Harbor, or Sarasota office, and bring any X-rays or MRI reports you already have.
Frequently Asked Questions
How long does frozen shoulder last?
Without treatment, frozen shoulder frequently runs one to three years from the first pain to recovered motion. A few resolve faster, and a few take longer. Treatment aims to make that stretch less painful and to bring motion back sooner.
Should I stretch a frozen shoulder if it hurts?
In the painful early stage, I prefer short, frequent stretches that stay inside a tolerable range. Forcing the shoulder through sharp pain tends to inflame the capsule further. As the pain settles, your therapist can progress the stretching.
Does a cortisone injection help frozen shoulder?
For patients in the painful stage, an injection into the joint might ease pain and make therapy easier to do. It treats pain rather than stiffness, so it works best paired with physical therapy.
Will I need surgery for frozen shoulder?
Probably not. Many frozen shoulders improve with therapy, pain control, and time. Procedures such as manipulation under anesthesia or arthroscopic capsular release are options for a shoulder that stays stiff after several months of consistent non-surgical care.
Can frozen shoulder come back?
It rarely returns in the same shoulder. Some people develop it later in the opposite shoulder, and people with diabetes appear to be at higher risk of having both sides affected.
