Every month someone sits in our clinic and shows us the same thing: an arm that will not go above shoulder height. That is frozen shoulder, or adhesive capsulitis, and it turns combing your hair or reaching for a shelf into a negotiation. It is painful, it is stubborn, and it attracts a remarkable amount of bad advice.
What a Frozen Shoulder Actually Is
The problem is the capsule, the sleeve of tissue around the shoulder joint. In a frozen shoulder it thickens and contracts, and the joint's movement shrinks. The result is pain plus a hard, mechanical restriction: the arm simply will not move past a point. Nobody fully knows why it strikes one person and not another. Diabetes is the clearest risk factor, then shoulder injuries or surgery followed by long immobility, and a handful of systemic diseases. What every case shares is a capsule that has decided to shrink.
Unfreezing Is a Slow Negotiation
The treatment is movement, but on the capsule's terms, not yours. Gentle, progressive range-of-motion work is the foundation, and a physiotherapist's job is to pitch it to your stage: too aggressive and the shoulder flares and freezes harder, too timid and nothing changes. Manual therapy supports it, easing the joint enough that the exercises can be done. Getting the dosage right is why supervision matters at the start.
Where Heat Fits
Yes, with a sensible job to do. Heat increases blood flow and softens the muscular guarding around a frozen shoulder, so a warm compress or a warm shower before exercising makes the range-of-motion work less painful and more productive. What heat does not do is thaw the capsule itself. Treat it as preparation, not treatment.
It Thaws on Its Own, Eventually
Left entirely alone, most frozen shoulders thaw over two to three years. Most is doing a lot of work in that sentence. Some never fully recover their range without treatment, and two to three years is a long time to dress one-handed. If your goal is the fastest and most complete recovery, treatment is not optional.
Massage: Useful, Not the Treatment
It can help, in a supporting role. Massage relaxes the muscles guarding around the capsule, which makes the real work, the exercises, easier to do. It is a complement to physiotherapy, not an alternative. And get it from someone who knows what a frozen shoulder is: aggressive deep-tissue work on an irritable shoulder can set you back weeks.
What We Actually Do in the Clinic
A good programme has five moving parts, none of them optional:
- Exercise matched to the stage: built around your current range and pain, progressed systematically rather than by a fixed calendar
- Manual therapy: hands-on joint mobilisation and soft-tissue work to loosen the joint enough that exercise is tolerable
- Education: knowing your stage, and why the daily home exercises matter more than anything we do in the room
- Pain management: adjuncts that take the edge off so the exercise programme can continue
- Deliberate progression: advancing load and range carefully, because a flare costs weeks
The Other Side Is at Risk
It can, though how likely varies from person to person. The fact worth knowing: the opposite shoulder is at elevated risk once you have had one frozen shoulder. Mention it to your physiotherapist early rather than after it has started freezing.
The Honest Version
There is no shortcut here, and anyone selling one is selling something else. A frozen shoulder yields to patience, consistency, and a plan that changes as the stages change: physiotherapy, heat, targeted exercise, and medical management where it adds something. It takes months. But shoulders do thaw, and the ones worked steadily from early on recover best.
