What is Polymyalgia Rheumatica

Polymyalgia rheumatica is an inflammatory disorder that causes muscle pain and stiffness, primarily in the shoulders, neck, and hips. It predominantly affects individuals over the age of 50 and is characterized by a rapid response to corticosteroid treatment, which is often used as both a diagnostic indicator and a primary therapy.

What are the primary symptoms of Polymyalgia Rheumatica?

The hallmark of Polymyalgia rheumatica is significant stiffness in the morning lasting longer than 45 minutes. Patients often struggle with basic activities like putting on a coat, rising from a chair, or rolling over in bed. Unlike conditions that primarily affect the joints, Polymyalgia rheumatica centers on the muscles and the soft tissues surrounding the joints, leading to systemic symptoms such as low-grade fever, fatigue, and unintended weight loss.

Who is most likely to develop Polymyalgia Rheumatica?

Polymyalgia rheumatica is rarely seen in people under age 50, with the average age of onset being around 70 to 75 years old. Women are affected approximately two to three times more frequently than men. While the exact cause remains unknown, it is believed to result from a combination of genetic predisposition and environmental triggers, such as an infection, that initiate an autoimmune response.

How does Polymyalgia Rheumatica differ from other conditions?

It is common to confuse Polymyalgia rheumatica with other inflammatory conditions, but several key factors help clinicians differentiate it:

• Giant Cell Arteritis (GCA): Approximately 15% of patients with Polymyalgia rheumatica also have GCA, a serious condition involving inflammation of the arteries that can lead to vision loss.


• Blood Markers: Patients typically show elevated inflammatory markers, such as Erythrocyte Sedimentation Rate (ESR) or C-reactive protein (CRP).


• Treatment Response: A hallmark of Polymyalgia rheumatica is the dramatic improvement in symptoms within days of starting low-dose prednisone.

Next steps for patients

• Consult a rheumatologist for a formal evaluation and to rule out Giant Cell Arteritis.


• Monitor for "red flag" symptoms like new headaches, jaw pain, or vision changes.
