Frozen Shoulder Treatment in East Sussex: What Actually Helps at Each Stage

Adhesive capsulitis is a progressive thickening and contracture of the capsule around the shoulder joint. The clinical signature is loss of passive external rotation: when someone else turns your relaxed arm outwards, it stops early and it hurts. That is what separates it from a rotator cuff problem, where passive movement is usually preserved even when active movement is painful.

Other features that point to it: pain that started without an obvious injury, night pain that stops you lying on that side, and a shoulder getting progressively stiffer in all directions rather than in one. It most commonly appears between the ages of 40 and 60, and it is considerably more common in people with diabetes, which is worth knowing because those cases tend to be more stubborn and last longer.

Imaging does not diagnose it. Scans are used to rule other things out, particularly where the history is atypical or the shoulder is stiff after an injury. Our page on shoulder pain covers the wider set of causes.

• Freezing (roughly 2 to 9 months): pain dominates and range is falling. This is the phase where aggressive stretching makes things worse. The priorities are pain control, sleep, and gentle movement within tolerance.
• Frozen (roughly 4 to 12 months): pain begins to settle, stiffness is the main problem. This is where sustained, progressive range of movement work and strengthening earn their place.
• Thawing (roughly 5 to 24 months): range gradually returns. Strength work matters here, because a shoulder that has been guarded for a year is weak as well as stiff.

The stages overlap and the timings vary a great deal. Getting the stage right matters more than getting the label right, because the treatment that helps in the frozen phase is exactly the treatment that flares the freezing phase.

Corticosteroid injection gives reliable short-term pain relief, and it is most valuable in the painful freezing phase where it can restore sleep and make movement possible. The relief is measured in weeks to a few months rather than being permanent.

Injection plus exercise beats either alone. A Cochrane review of manual therapy and exercise for adhesive capsulitis found the available evidence to be low quality overall, and the more consistent finding across the literature is that combining a corticosteroid injection with a structured exercise programme produces better outcomes than exercise on its own in the short term.

Hydrodilatation, an injection of fluid under pressure to stretch the capsule, is offered in some centres and has reasonable support for improving range and pain in the frozen phase.

Manipulation under anaesthetic and arthroscopic capsular release are reserved for shoulders that remain severely restricted after several months of proper conservative treatment.

What does not help: forcing range into sharp pain, and doing nothing at all for a year. The honest summary is that most shoulders recover substantially with time, and that treatment mainly changes how painful and how disabling the journey is.

• Little and often. Five or six short sessions a day of movement within a tolerable range beats one heroic session.
• Judge by the next morning. Discomfort during exercise that settles within an hour or two is acceptable. A shoulder that is angrier the following morning means the dose was too high.
• Protect sleep. Pillow positioning, side of lying and, where appropriate, discussing pain relief with your GP. Sleep loss makes pain worse and it is the part people tolerate for months without mentioning.
• Strengthen as range returns. Rotator cuff and scapular work from the frozen phase onwards, so the shoulder is usable when the range comes back.
• Keep the rest of the arm working. Elbow, wrist and grip stay in use, and the neck often needs attention because of months of guarded posture.

What has changed in clinic is the point at which people arrive. More are turning up mid-way through, several months in, having had an injection that worked for six weeks and then nothing since. The shoulder is no longer acutely painful and it is now very stiff, and the plan they were given has quietly expired.

That is a treatable position, and it needs the stage to be identified rather than assumed. A shoulder still in the freezing phase gets flared by the exact programme that helps a frozen one, which is why generic frozen shoulder exercise sheets have such a mixed reputation. Locally, musculoskeletal referrals across the county route through East Sussex Healthcare NHS Trust's MSK therapy services, where injection and specialist opinion sit. What the pathway is less able to provide is the year of regular, adjusted follow-up that this condition needs, and that gap is where most of the avoidable suffering happens. The other detail worth flagging: if you have diabetes, expect a slower course and plan for it rather than concluding at month eight that treatment has failed.

If you want to understand the whole picture before deciding what to do, our shoulder pain page sets out how the different causes are separated.

How long does frozen shoulder last?
Commonly one to two years from start to substantial recovery, sometimes longer in people with diabetes. A minority are left with some permanent loss of end range, which is usually not limiting.

Should I push through the pain to get movement back?
No. Forcing range in the painful phase reliably makes it worse. Frequent movement within a tolerable range is what works.

Is an injection worth having?
In the painful phase, often yes, particularly if night pain is stopping you sleeping. It works best combined with a structured exercise programme rather than on its own.

Can it happen in the other shoulder?
It can. Recurrence in the same shoulder is uncommon; involvement of the other side at some point is recognised.

Will I need surgery?
Most people do not. Manipulation under anaesthetic or capsular release is considered when a shoulder stays severely restricted despite several months of proper treatment.
