Frozen shoulder: why it hurts to reach behind you, and how long it really takes

It starts as something you can ignore. Reaching for a seatbelt is awkward. Fastening a bra behind your back is awkward. Then one morning you reach up to a high shelf and the arm simply stops, well before the top, and the stop is not about strength.

What has actually happened

The capsule around the shoulder joint — the sleeve of connective tissue that holds it together — has thickened and contracted. The joint is not blocked by a muscle. The container it lives in has literally become smaller.

That is why forcing it does not work and why an aggressive massage therapist can genuinely set you back. You are not stretching a tight muscle. You are pulling on inflamed connective tissue, and it responds to force by tightening further.

It shows up most often between forty and sixty, more in women, and notably more in people with diabetes or thyroid conditions. It can also follow a period of not moving the arm — after an injury elsewhere, or after surgery.

Three phases, and each wants something different

Freezing. Pain leads, movement is shrinking, nights are the worst part. Deep work here makes it angrier. What helps is gentle work on everything around the joint — neck, upper back, chest, the shoulder blade — which are all overworking to compensate. This phase is where people burn out emotionally, so making the rest of the body comfortable matters more than it sounds.

Frozen. Pain settles, stiffness is the main complaint. Now hands-on work earns its place: sustained work along the capsule, the muscles under and around the shoulder blade, and careful passive movement at the edge of range — not past it.

Thawing. Range returns gradually. Here the work is about making sure it returns evenly, because the compensations you built over a year do not disappear on their own. The shoulder blade in particular usually needs re-teaching.

The honest timeline

Months, not weeks. Often a year or more from start to finish, and no bodywork changes that fundamentally.

What it changes is how much of that time you spend in pain, how much shoulder function you keep in the meantime, and how much collateral tightness you carry out the other side. That is not a small offer. It is just not the offer people hope for, and pretending otherwise would be dishonest.

What to do between sessions

Move it often and gently, well within the range that does not hurt. The pendulum — lean forward, let the arm hang, draw small circles with the weight of the arm alone — is the most useful thing you can do, several times a day.

And see a physician if you have not. Frozen shoulder is a diagnosis of exclusion, and a few things that look exactly like it are not it.
