The hormonal shifts that accompany perimenopause and menopause may significantly raise the risk of developing frozen shoulder, a painful and debilitating condition that restricts arm movement, according to orthopedic specialists. While many women attribute shoulder pain to muscle strain or injury, the underlying cause may be linked to estrogen loss and its effects on joint health. Experts are calling for greater awareness of this connection, as early diagnosis can simplify treatment.
Frozen shoulder, medically known as adhesive capsulitis, occurs when the shoulder capsule — a fibrous sheath surrounding the joint — becomes thickened and inflamed. The condition typically advances through three phases: a freezing stage lasting several months with severe pain, a frozen stage where the shoulder stiffens and becomes difficult to use for up to a year, and a thawing stage when mobility gradually returns. Although frozen shoulder affects about 2 to 5 percent of the general population, it disproportionately strikes women between the ages of 40 and 60.
The link to perimenopause and menopause lies in the protective role of estrogen. As estrogen levels decline, musculoskeletal tissue loses elasticity and becomes more prone to inflammation. This hormonal change also increases susceptibility to endocrine disorders such as diabetes and thyroid disease, which are themselves risk factors for frozen shoulder. Dr. Jocelyn Wittstein, a sports medicine specialist at Duke University, explains that the combination of estrogen withdrawal and metabolic changes likely triggers the condition in many midlife women.
Liz Gumbinner, a writer and Boston University instructor, first noticed a twinge in her right shoulder during the pandemic. She assumed she had pulled a muscle from home yoga and dance routines, but the pain escalated sharply, shooting down her arm whenever she extended it. She describes it as « worse than labor contractions. » Simple tasks like zipping a dress, turning off a light switch, or holding hands became impossible. It took several months before she received a diagnosis of frozen shoulder. Her story illustrates a common pattern: women often mistake the condition for a rotator cuff tear or biceps tendonitis.
Dr. Stephanie Wong, an orthopedic surgeon at UCSF, notes that frozen shoulder is what physicians call « the great mimicker » because its symptoms resemble those of other shoulder problems. The telltale sign during a clinical exam is that neither the patient nor the doctor can move the affected arm — it is literally frozen. X-rays or MRIs can help rule out other issues, but the diagnosis is primarily based on physical examination. Both Wong and Wittstein stress that early evaluation is crucial. « If you get into where you have really significant loss of motion, it takes longer to get better, » Wittstein says.
Standard treatment for frozen shoulder includes physical therapy focused on stretching and manual therapy, along with anti-inflammatory injections into the joint. Most patients recover within one to three years, and surgery is reserved for stubborn cases. Physical therapy must be performed under the guidance of an experienced therapist, as it can be uncomfortable. Promising new research suggests that hormone therapy may reduce the risk of developing frozen shoulder. Wittstein recently presented data on more than 10,000 women indicating an association between hormone therapy and a lower incidence of the condition. At UCSF, orthopedic and obstetrics-gynecology departments are jointly investigating whether hormone therapy can shorten the course of frozen shoulder.
However, not all women can benefit from hormone therapy. Breast cancer survivors who take aromatase inhibitors — a type of hormone therapy that drastically reduces estrogen — are at high risk for frozen shoulder and cannot use estrogen-based treatments. Wittstein describes this group as « a special at-risk population » that takes a « double hit. » For these women, early diagnosis and non-hormonal interventions become even more critical. Experts hope that increased awareness will help more midlife women recognize the symptoms and seek timely care, avoiding prolonged suffering and disability.
