Frozen Shoulder and Menopause

Why Women in Midlife Are Disproportionately Affected by Frozen Shoulder

If you're a woman in your 40s or 50s and your shoulder has started aching for no obvious reason — gradually becoming stiffer, more painful, and harder to move — there's a good chance you've been told it's "just a frozen shoulder." What you may not have been told is why frozen shoulder is so much more common in women at this particular stage of life, and what that means for how it should be managed.

The short answer? Your hormones are almost certainly part of the story.

What Is Frozen Shoulder?

Frozen shoulder — also called adhesive capsulitis — is a condition where the capsule surrounding the shoulder joint becomes inflamed and progressively thickens and tightens, dramatically limiting shoulder movement in all directions. It affects around 3–5% of the general population, but that number is significantly higher in women between the ages of 40 and 60.

In fact, roughly three-quarters of all frozen shoulder patients are female — and the peak window of onset maps almost precisely onto the perimenopausal and menopausal transition. This is not a coincidence.

The Three Stages — and Why Early Treatment Matters

Frozen shoulder is well known for following a predictable, if frustrating, three-stage course:

The Freezing Stage — Pain arrives first, often at night and at the outer edge of the shoulder. Movement gradually becomes more restricted. This stage can last anywhere from 2 to 9 months and is often the most painful period.

The Frozen Stage — Pain may begin to ease slightly, but stiffness takes centre stage. Everyday tasks like reaching overhead, doing up a bra, or getting dressed become genuinely difficult. This stage typically lasts 4 to 12 months.

The Thawing Stage — Movement slowly begins to return. This stage can last from 5 months to 2 years or more, and without active treatment, full mobility is not guaranteed.

Left completely untreated, the entire process can drag on for 18 months to 3 years — and some degree of residual stiffness is common in women who don't engage with physiotherapy. The message here is simple: don't wait.

The Menopause Connection — What the Research Is Telling Us

For years, clinicians observed the striking preponderance of frozen shoulder in perimenopausal women without fully understanding why. That picture is now becoming considerably clearer.

The role of Oestrogen

Oestrogen is not just a reproductive hormone. It plays a meaningful role in maintaining connective tissue health, moderating inflammation, and — crucially — preventing fibrosis, which is the excessive thickening and scarring of soft tissue. When oestrogen levels decline during perimenopause, these protective effects weaken.

Research has identified that oestrogen has direct anti-fibrotic properties — it helps regulate the signalling pathways that, when unchecked, drive the synovial inflammation and capsular thickening that characterise frozen shoulder. A 2025 paper published in the Journal of Steroid Biochemistry and Molecular Biology identified that oestrogen exerts these anti-fibrotic effects via the PI3K-Akt signalling pathway in shoulder tissue — providing a mechanistic explanation for why declining oestrogen levels may directly promote the development of adhesive capsulitis.

There's also a shift in the type of oestrogen circulating during perimenopause. Oestradiol — the potent, anti-inflammatory form of oestrogen dominant during reproductive years — is progressively replaced by oestrone, a weaker and more pro-inflammatory oestrogen. This shift may further tip the balance toward the kind of low-grade, persistent inflammation that sets the stage for frozen shoulder to take hold.

Research led by Duke Health orthopaedic surgeon Dr Jocelyn Wittstein — who co-authored the landmark 2024 paper coining the term "musculoskeletal syndrome of menopause" — found that postmenopausal women who were not receiving hormone replacement therapy had significantly greater odds of developing adhesive capsulitis than those who were. This was among the first studies to formally evaluate the protective role of HRT against frozen shoulder, and while larger prospective trials are still underway (including a dedicated RCT at UCSF currently recruiting), the biological plausibility is well established.

Women with additional risk factors — diabetes, thyroid disease, cardiovascular disease, or a history of shoulder trauma — carry a compounded risk during the perimenopausal window, as these conditions interact with hormonal changes to further predispose the shoulder capsule to fibrotic change.

Why This Matters for Your Treatment

Understanding that hormonal change is likely a contributing factor to frozen shoulder in midlife women has real implications for how it should be approached:

1. It helps explain why it happened — and you haven't done anything wrong. Many women with frozen shoulder have no identifiable injury or overuse history. The capsule stiffened because of a hormonal environment that made it more vulnerable, not because of something you lifted or a position you slept in. This context matters for reducing the frustration and self-blame that often accompany this condition.

2. It may warrant a conversation with your GP. If you're perimenopausal and develop frozen shoulder, the hormonal picture is part of your broader health context. A conversation with your GP about your broader menopausal health — including whether hormone therapy might be appropriate for you — is worth having. Physiotherapy addresses the shoulder mechanics; your GP can help address the systemic hormonal environment.

3. It reinforces why passive, "wait and see" approaches are particularly ill-suited to this population. Women in perimenopause are already contending with accelerating muscle loss, tendon vulnerability, and declining bone density. Prolonged shoulder immobility compounds all of these.

Early, active physiotherapy is especially important for preserving function and

preventing the downstream losses that compound during this life stage.

What Physiotherapy Can Actually Do

The good news is that physiotherapy has a strong evidence base for every stage of frozen shoulder — and an experienced physiotherapist will adjust the approach based on which stage you're in.

In the freezing stage, when pain is the dominant feature, treatment focuses on pain modulation and maintaining what movement you have without provoking a flare. This typically includes gentle manual therapy, soft tissue work, dry needling for associated muscle spasm and pain, and hydrotherapy — where the warmth and buoyancy of water allow guided movement with significantly less pain and load. Getting your sleep manageable is also a clinical priority; uncontrolled night pain leads to fatigue, avoidance, and muscle guarding, all of which worsen the condition.

In the frozen stage, once pain has settled to a more manageable level, the focus shifts toward progressive mobilisation — restoring range of motion through a combination of manual joint mobilisation, targeted stretching, and progressive strengthening. The principle here is graduated, consistent work rather than aggressive force. Forcing a frozen shoulder does not speed recovery and carries real risk of injury.

In the thawing stage, the emphasis moves to restoring full strength and function. Many women arrive at this stage with significant rotator cuff weakness and altered movement patterns from months of compensation — structured rehabilitation is essential to avoid re-sensitisation and residual dysfunction.

Corticosteroid injection can play a role — particularly in the freezing stage, where significant inflammation is present — but evidence suggests it provides primarily short-term benefit and does not accelerate long-term recovery. It can be a useful tool for bringing pain under control enough to allow active physiotherapy to begin.

The Bigger Picture

Frozen shoulder in perimenopause is not just a local shoulder problem. It's one manifestation of what researchers are increasingly referring to as the musculoskeletal syndrome of menopause — the cluster of joint, tendon, muscle, and bone changes driven by declining oestrogen that affect a significant proportion of women during midlife. Understanding this broader context helps make sense of why frozen shoulder, gluteal tendinopathy, joint aches, and accelerated muscle loss can all seem to arrive at the same time.

The single most empowering thing you can do when symptoms start is seek early assessment. An accurate diagnosis means the right treatment from the right stage — and a significantly better outlook than the slow, default "wait it out" approach that still, unfortunately, too many women are offered.
