Frozen shoulder.
Reaching behind your back stopped being possible and you cannot say exactly when. Which phase you are in decides what should happen next.
The capsule shrank.
The shoulder joint sits inside a capsule — a sleeve of connective tissue that normally has enough slack to permit the enormous range the shoulder is capable of. In frozen shoulder, that capsule thickens, becomes inflamed, and contracts. The available volume inside the joint physically reduces, and the arm cannot move through range because there is no longer room for it to do so.
This is what separates frozen shoulder from most other shoulder problems. With a rotator cuff tear or impingement, you may struggle to lift the arm yourself, but someone else can usually move it for you. With frozen shoulder, passive movement is restricted too. External rotation — turning the forearm outward with the elbow at your side — is characteristically the first and worst affected, and that pattern is close to diagnostic.
It often begins without any injury at all. It is more common in people with diabetes and thyroid disorders, more common in women, and most common between roughly forty and sixty. It can also follow a period of immobilisation after a different injury or a surgery.
The condition moves through phases, and this is the practical key to managing it. Aggressive stretching in the early painful phase tends to increase irritability without gaining anything. The same stretching later is exactly right. At our Jacksonville and Orange Park offices, the first job is establishing which phase you are in.
Does this sound familiar?
Match the treatment to the phase.
The three phases, and why they matter
The freezing phase is the painful one. Pain is often severe, disturbs sleep, and range is progressively lost. This typically runs several months. Treatment here targets pain and preserving what movement you have — aggressive stretching now generally increases irritability without producing lasting gains.
The frozen phase is the stiff one. Pain settles substantially, but range is at its most restricted and daily tasks are hardest. This is where mobilisation and progressively firmer stretching begin to earn their place, because the tissue is less reactive.
The thawing phase is gradual return. Range comes back over months. Treatment focuses on restoring end range efficiently and rebuilding the strength lost through a long period of reduced use.
Someone in the freezing phase being pushed hard into painful range is the most common way this gets managed badly — and the reason people often say physical therapy made it worse.
Frozen shoulder or something else?
The passive range test does most of the diagnostic work. A rotator cuff tear generally leaves passive movement available even where active movement is weak or painful. Impingement typically produces a painful arc through a specific range rather than a hard stop.
Frozen shoulder produces a firm, capsular end-feel with restriction in a characteristic pattern — external rotation most affected, then abduction, then internal rotation. That pattern in someone in the right age range, without an injury, is fairly distinctive.
Arthritis of the shoulder joint itself can also restrict passive range and is worth distinguishing, usually with imaging where the history suggests it.
The diabetes connection
Frozen shoulder is substantially more common in people with diabetes, and it tends to be more severe and longer-lasting in that group. It is also associated with thyroid disorders.
This is worth knowing for two reasons. If you have unexplained frozen shoulder and have not had recent bloodwork, it is reasonable to ask your physician about screening. And if you do have diabetes, it helps to have realistic expectations about the timeline rather than assuming treatment is failing.
Bilateral frozen shoulder — either simultaneously or the second following the first — is also more common in this group.
What conservative care realistically achieves
Frozen shoulder is generally self-limiting, resolving over a long period. That fact is often used to argue for doing nothing, which underestimates what the condition costs someone over one to three years.
Realistic goals are meaningful: reducing pain during the worst phase, preserving sleep, maintaining function in the surrounding structures so the whole arm and neck do not stiffen in compensation, and restoring range efficiently once the capsule begins to release.
Where pain remains severe and unresponsive, a corticosteroid injection into the joint during the painful phase is an option worth discussing with a physician. We do not perform injections, and where that appears to be the right step we will say so and coordinate rather than keep you in treatment that is not moving.
